China LED Video Wall Outdoor Rental Manufacturer | FAT

You have short-listed three Chinese manufacturers for a 220-cabinet outdoor P4.8 video wall PO destined for European summer festival touring. The proposals look similar: comparable FOB Shenzhen unit price, similar IP-rating claims (IP65 front / IP54 rear), similar refresh-rate specs (3,840 Hz), similar processor compatibility (Novastar / Colorlight / Brompton). You have already read the audit checklists, the tier taxonomies, the RMA and warranty playbooks, and the Q4 slot reservation guides. The final question that still separates a good outdoor PO from a bad one is this: have you physically qualified the cabinets in Shenzhen before the container is sealed?

This article is that missing playbook. It documents the environmental qualification testing regime and the buyer Factory Acceptance Test (FAT) protocol that professional touring rental companies, XR studio operators, festival production houses, and stadium AV integrators run inside the manufacturer’s own factory in Shenzhen the week before the 40HQ container is sealed and loaded. It is different from the audit checklists (which look at factory capability), the RMA playbooks (which look at post-sale service), the tier taxonomies (which look at factory selection), and the wholesale portfolio views (which look at strategic sourcing). It looks at one thing: the day you fly to Shenzhen with your test-instrument case and physically verify that this specific batch of cabinets meets the environmental spec on your PO.

Opening Case Study: The IP65 Claim That Failed the Rain Chamber

A UK-based touring rental company operating a 220-cabinet outdoor P4.8 fleet for 2026 European festival tour. Manufacturer selected: a Tier 2 Shenzhen-based OEM with 12 years export experience, IP65 claim on the cabinet front and IP54 claim on the cabinet rear, PE-stamped structural drawings, delivered on time to prior POs.

Pre-shipment buyer FAT scheduled 5 days before container seal. Buyer team: procurement lead, senior video engineer, freelance structural PE consultant. Test instrument case: portable IP-rating rain-spray chamber (IEC 60529 IPX5-IPX6 test rig, USD 8,000-16,000 portable unit), UV lux-meter, delta-E colorimeter (Konica Minolta CA-410 or equivalent, USD 24,000-38,000), thermal-imaging camera (FLIR E76 or equivalent, USD 4,800-7,200), power-quality analyzer, hipot tester, laser measurement tool, digital caliper, sound-level meter for fan noise, weighing scales, torque wrench, and a laptop running the manufacturer’s calibration software.

The team pulled 12 cabinets at random from the sealed production batch (5% of the 220-cabinet PO). Rain-chamber test (IEC 60529 IPX5 spray, 12.5 l/min from a 6.3mm nozzle at 2.5-3 m distance for 3 minutes each side) revealed water ingress on 3 of the 12 cabinets through the rear cable-gland assembly. Root cause on tear-down: the cable-gland rubber grommet had been sourced from a secondary supplier in the current production batch (the primary supplier’s on-time delivery slipped), and the grommet OD tolerance was 0.4mm loose. Water tracked past the grommet, into the receiver-card enclosure, and pooled on the PSU heat-sink assembly.

The manufacturer’s initial response was to argue that IP65 claim was for the front face only (rated IP65) and the rear was IP54 (dust-protected but not water-jet protected). The buyer’s PE consultant pushed back with the following: the PO explicitly stated “IP65 front, IP54 rear, water-jet drainage path routed away from PSU enclosure” and the test protocol IPX5 does not stress the IP54 rear rating — it stresses only the rear cable-gland assembly which the buyer’s PO had specified must maintain water-tight seal at IPX4 minimum against wind-driven rain (a spec the buyer added because the fleet would deploy at coastal festivals in Netherlands and Portugal).

Outcome: manufacturer agreed to rework the affected batch (grommet supplier reverted to primary; new grommets pressed into all 220 cabinets over 6 additional production days; secondary rain-chamber test on 20 more random cabinets confirmed 100% pass). PO shipping delayed 8 days; buyer’s Q1 tour date held because the 6-week ex-Shenzhen transit still gave them 4 weeks of contingency. Total remediation cost borne by the manufacturer (grommet parts + labour) approximately USD 6,200. Total remediation cost had this issue been discovered in the field at the first Portuguese festival: USD 68,000-142,000 (show downtime + spare-cabinet dispatch + tour rerouting + IATSE overtime).

This case study is the reason buyer FAT exists. The IP-rating claim on the datasheet is not the same as verified IP performance on this batch. FAT is where you close that gap.

The Environmental Qualification Framework: 9 Test Domains

1. IP-rating verification (IEC 60529)

Ingress Protection ratings on outdoor cabinets: IP54 (dust-protected, water splash), IP65 (dust-tight, water-jet), IP66 (dust-tight, powerful water-jet), IP67 (dust-tight, submersion 1m/30min), IP68 (dust-tight, continuous submersion). Common outdoor rental spec: IP65 front / IP54 rear, occasionally IP66 for coastal/marine. Test protocol: rain-spray chamber IPX4 (splashing water), IPX5 (water jet 12.5 l/min from 6.3mm nozzle at 2.5-3m), IPX6 (powerful water jet 100 l/min from 12.5mm nozzle at 2.5-3m). Buyer FAT: sample 5-10% of PO, spray each side 3 minutes minimum, tear down 2-3 cabinets and inspect internal moisture presence with paper wipe on receiver / PSU / LED module rear.

2. UV weathering resistance (ASTM G155 / ISO 4892-2)

Outdoor cabinets face UV degradation on cabinet face frame, front mask, LED module lens, silicone gaskets, cable insulation. Accelerated UV testing (xenon-arc lamp 340 nm intensity) simulates months of outdoor exposure in hours. Full ASTM G155 protocol is a 1,000-3,000 hour lab test conducted at a certified test house (SGS Shenzhen, TUV Rheinland Shenzhen, Bureau Veritas Shenzhen, Intertek Shenzhen). Buyer FAT typically requests a signed UV test report on the specific cabinet model within the past 12 months rather than running the test in-line (physical UV testing is not practical during a 5-day FAT visit).

3. Salt-spray / salt-fog corrosion (ISO 9227 / ASTM B117)

Coastal, marine, and cruise-line deployments face chloride corrosion on cabinet frames, hardware, connector pins, PSU heat-sinks, mounting hardware. Salt-spray test (5% NaCl solution, 35°C, continuous or cyclic exposure) validates corrosion resistance. Typical qualification: 96-hour continuous salt-spray for coastal fleets, 240-hour for marine/cruise-ship deployments. Buyer FAT: request signed salt-spray test report; for high-risk deployments consider a supplementary 96-hour salt-spray test on 2-3 cabinet samples at a certified test house before container ships (adds 5-7 days to schedule; adds USD 1,200-2,800 test cost).

4. Thermal cycling / temperature and humidity aging (IEC 60068-2-14 / IEC 60068-2-30)

Outdoor cabinets face daily thermal cycling (day/night delta of 15-30°C) and seasonal cycling (winter/summer delta of 40-70°C in continental climates). Thermal cycling test (-20°C to +55°C, 5-10 cycles, humidity 90% RH at high temp) validates solder joint reliability, capacitor ESR stability, LED die-attach durability, and gasket sealing under thermal expansion / contraction. Buyer FAT: request signed thermal-cycling report; verify the report matches this specific cabinet model and this production batch date range.

5. Vibration and shock (IEC 60068-2-6 / IEC 60068-2-27)

Touring rental cabinets face repeated truck-transport vibration, forklift handling shock, and load-in/load-out drop-testing. Vibration test (5-500 Hz sinusoidal sweep, 1-3g acceleration, multiple axes) and shock test (30-50g half-sine pulse) validate cabinet frame integrity, PSU mount stability, cable connector retention, and LED module attachment. Buyer FAT: request signed vibration/shock report; physically inspect road-case fit and shock-mount integrity.

6. Wind-load structural (PE-stamped calculations)

Outdoor mega-walls face wind loading proportional to face area and dynamic pressure. Standard reference: ASCE 7-22 (US), Eurocode EN 1991-1-4 (EU), NBCC 2020 (Canada), AS/NZS 1170.2 (AU/NZ). Typical outdoor rental spec: 80 mph (129 km/h) survival wind on freestanding truss configuration with ballast, 55 mph (89 km/h) operating wind. Buyer FAT: verify PE-stamped structural drawings for the cabinet-plus-truss-plus-ballast system, verify sail-area calculations, verify ballast plan (typical 8-14 kg/m2 of wall face area for 60-80 mph survival), and verify the PE stamp matches the jurisdiction (US PE state license, EU CEng, UK CEng, Canada P.Eng., AU RPEQ).

7. Sunlight brightness and daylight readability

Outdoor cabinets face direct sunlight requiring 5,500-8,000+ nits peak brightness for daylight readability. Verification: on-site brightness meter (Konica Minolta LS-160 or equivalent, USD 3,200-4,800) at cabinet face, verify 5,500 nits at high-drive mode, verify auto-dimming curve for evening / night operation (typical target: 800-1,200 nits at 22:00 local time to avoid over-bright glare complaints).

8. Colour uniformity / delta-E calibration

Broadcast-tier outdoor deployments require delta-E under 2 (JND threshold) across the cabinet face and across a multi-cabinet wall configuration. Verification: delta-E colorimeter (Konica Minolta CA-410, USD 24,000-38,000) at 9-point cabinet face grid, verify factory calibration LUT is loaded, verify batch calibration consistency across the 5-10% cabinet sample, verify processor-side calibration workflow.

9. Refresh rate and processor compatibility

Broadcast-camera-safe refresh rate: 3,840 Hz minimum; 7,680 Hz for high-end XR / virtual production. Verification: high-speed camera capture at 4K/60p and 4K/120p, verify no scan-line beating, verify no black-frame flicker, verify no colour-fringe artifact. Processor compatibility: verify Novastar / Colorlight / Brompton / MegaPixel VR processor integration on the buyer’s specific rig configuration.

The 5-Day Buyer FAT Protocol in Shenzhen

Day 1: Factory-floor walkthrough and PO verification

Arrive at manufacturer’s Shenzhen factory (typical location: Baoan, Longgang, or Guangming district). Meet the QC director, production director, and export sales lead. Review PO specification against production QC records. Verify serial-number-to-batch-number mapping for the specific 220-cabinet PO. Verify the production date range is single-batch (not blended across 3-5 batches). Photograph the pallet-load layout, cable-drum inventory, and PSU stock. Confirm the 40HQ container booking date, forwarder ETA, and Yantian port drayage schedule.

Day 2: Random-sample cabinet pull and visual inspection

Pull 12-22 cabinets at random from the sealed production batch (5-10% of PO). Verify cabinet serial numbers against PO batch record. Weigh 3-5 cabinets on portable scale, verify weight consistency (typical outdoor P4.8 cabinet: 28-36 kg, tolerance ±0.5 kg). Digital-caliper cabinet OD, verify tolerance ±0.3mm on interlocking dovetail. Torque-check corner screws to spec. Visual inspect cabinet face (LED module face-plate flatness, mask alignment, gasket seating), rear panel (cable-gland torque, PSU mount, receiver-card LED status), and connector pins. Photograph each side of each cabinet for the FAT record.

Day 3: Environmental testing and calibration verification

Portable rain-chamber test (IPX5, 3 minutes per side) on 5-8 cabinets. Tear down 2-3 rain-tested cabinets, verify no internal moisture with paper-wipe on receiver / PSU / LED module rear. Delta-E colorimeter grid test on 5-8 cabinets, verify factory LUT delta-E under 2 on 9-point grid. Brightness verification: run cabinet at spec drive current, verify 5,500-8,000 nits peak. Refresh-rate verification: connect via specified processor, capture with high-speed camera 4K/60p, verify no scan-line beating. Fan-noise check (some outdoor cabinets have active cooling; measure at 1m distance, verify under 55 dBA). Thermal-imaging inspection of cabinets running at spec load for 45-90 minutes, verify PSU heat-sink temperature under 75°C and LED module surface under 65°C.

Day 4: Wall-configuration build and integrated test

Ask the manufacturer to build a 20-40 cabinet integrated wall configuration on the factory floor (typical 5×4 or 5×8 layout, 4-8 m2 wall face). Verify seam-line flatness with laser measurement (tolerance ±0.4mm across the wall). Verify seam-line delta-E under 3 with colorimeter (calibrated across the wall, not just per-cabinet). Run 4-8 hours of stress content (rolling colours, camera-safe test patterns, high-motion content) at spec brightness and verify no failure, no calibration drift, no thermal shutdown. Verify processor-side firmware version consistency across all cabinets in the wall configuration. Capture the wall configuration on high-speed camera at 4K/60p.

Day 5: Documentation review, container-load supervision, sign-off

Review the FAT record: photograph log, test-result log, delta-E record, brightness record, thermal-image record, wall-configuration video, cabinet weight/dimensions log. Sign the FAT closeout document with the manufacturer’s QC director. Attend the 40HQ container loading (typical outdoor P4.8 fleet: 55-72 cabinets per 40HQ depending on cabinet size, plus road cases, cabling, mounting hardware, and spare-parts kit). Verify container-load sequence, dunnage placement, and container seal number. Photograph container seal for the shipping record. Confirm forwarder pickup schedule (typical Yantian port drayage: same-day to next-day; container-yard cutoff typically 48 hours before vessel departure).

Buyer FAT Cost and Time Budget

The FAT budget looks large in absolute dollars but is small relative to the PO value (typical outdoor P4.8 220-cabinet PO FOB Shenzhen: USD 620,000-820,000). FAT typically runs 3-12% of PO value and is amortized across multiple POs when the buyer owns the test-instrument case. The return-on-investment case: a single batch defect discovered at FAT and remediated pre-shipment (typical remediation cost USD 3,000-14,000 borne by manufacturer) versus discovered in the field (typical show-downtime cost USD 40,000-120,000 borne by buyer). FAT typically pays for itself on any PO where the buyer detects a single significant defect.

Environmental Qualification Test-Report Registry: What to Request Before FAT

Before flying to Shenzhen, request the following signed reports from the manufacturer. If any are missing or older than 12 months for the specific cabinet model, escalate before booking travel.

• IP-rating test report (IEC 60529) from a certified test house (SGS / TUV Rheinland / Bureau Veritas / Intertek / DEKRA / UL) on the specific cabinet model within the past 12-24 months.
• UV weathering test report (ASTM G155 or ISO 4892-2) minimum 1,000 hours xenon-arc exposure with pass/fail criteria on cabinet face-frame, gaskets, and LED module lens.
• Salt-spray corrosion test report (ISO 9227 or ASTM B117) minimum 96 hours for coastal deployments, 240 hours for marine / cruise-ship.
• Thermal cycling test report (IEC 60068-2-14) -20 to +55 °C, minimum 5-10 cycles, with humidity 85-95% RH at high temp.

• EMC compliance report (FCC Part 15 for US / CE EMC 2014/30/EU for EU / CCC for China) on the specific cabinet model.
• Safety compliance report (UL 48 / UL 8750 for US / CE LVD 2014/35/EU for EU / CCC for China) on the specific cabinet model.
• PE-stamped structural drawings for the cabinet-plus-truss-plus-ballast system on the jurisdictions of intended deployment (US state PE / EU CEng / UK CEng / Canada P.Eng. / AU RPEQ).
• Wind-load calculation report per ASCE 7-22 (US) / Eurocode EN 1991-1-4 (EU) / NBCC 2020 (Canada) / AS/NZS 1170.2 (AU/NZ).
• Refresh-rate performance report with high-speed camera capture verifying 3,840 Hz (or 7,680 Hz for XR / virtual production) on the specific cabinet model.
• Delta-E calibration report per-cabinet from factory calibration line with 9-point face-grid measurements.
• RoHS / REACH compliance report for EU customs entry.
• Factory ISO 9001 quality management certificate current and valid.
• Factory ISO 14001 environmental management certificate if the buyer’s ESG procurement policy requires.
• Factory ISO 45001 occupational health and safety certificate if the buyer’s ESG procurement policy requires.

Buyer FAT vs Third-Party Inspection: When to Use Which

Two options exist for verifying a Chinese cabinet PO before shipment. Buyer FAT (fly to Shenzhen with your own team and test-instrument case) and third-party inspection (engage SGS / TUV Rheinland / Bureau Veritas / Intertek / Cotecna / QIMA to perform the FAT on your behalf).

Buyer FAT: when to use

• High-value PO (typically USD 400,000+ FOB Shenzhen).
• High show-downtime cost per event (broadcast / touring / festival scope).
• New manufacturer relationship (first 1-3 POs before trust is established).
• Complex spec (custom cabinet size, custom IP rating, custom mounting system).
• Buyer video engineer and PE consultant availability.

Third-party inspection: when to use

• Lower-value PO (typically USD 100,000-400,000 FOB Shenzhen).
• Repeat manufacturer relationship (5+ POs of similar spec).
• Standard spec (off-the-shelf cabinet model with published test reports).
• Time-constrained schedule (no available window for buyer team travel).
• Multiple concurrent POs across geographies (third-party inspection scales; buyer FAT does not).

Typical third-party inspection cost: USD 400-1,200 per man-day, minimum 2-day inspection at USD 1,600-3,600 per PO, up to 5-day inspection at USD 4,000-12,000 per PO. Third-party inspection is 20-60% the cost of buyer FAT but does not include senior video engineer judgment, PE structural review, or buyer-side calibration verification.

13 Common Buyer FAT Mistakes

1. Trusting the datasheet IP rating without physical verification on this batch. Datasheet IP ratings are for the cabinet model, not for this specific production batch; batch-level variance in gasket / grommet / seal suppliers is the primary IP-failure driver.
2. Sampling too few cabinets. Sampling 1-2 cabinets from a 220-cabinet PO does not statistically represent the batch; industry standard is 5-10% random sample.
3. Not requesting single-batch delivery in writing. Blended-batch delivery causes calibration drift, silicon-revision drift, and gasket-supplier drift within a single PO. Verify batch consistency at Day 1 of FAT.
4. Skipping the wall-configuration integrated test on Day 4. Per-cabinet testing does not surface seam-line delta-E drift, cross-cabinet firmware version drift, or processor-side integration issues; wall-configuration test is critical.
5. Not photographing the container seal at loading. Container seal photograph is the shipping-record evidence that no substitution occurred between FAT sign-off and container arrival.
6. Not verifying the interpreter’s technical background. A generalist interpreter without LED-industry vocabulary loses 30-50% of the technical discussion; hire a specialist.
7. Missing the PE-stamped drawing review before travel. Structural PE review is best done 2-4 days pre-FAT so any structural issue is escalated before you fly.
8. Not requesting the specific test-report registry before FAT. Test reports older than 12 months for the specific cabinet model are stale; missing reports indicate the manufacturer does not routinely re-certify.
9. Not verifying weight and dimensions on portable scale. Cabinet weight variance beyond ±0.5 kg suggests batch inconsistency in cabinet frame casting or PSU sourcing.
10. Skipping thermal-imaging inspection at 45-90 minute sustained load. Cold-start thermal imaging misses PSU heat-sink saturation and LED module thermal drift that manifest after sustained operation.
11. Not verifying processor firmware version consistency. Processor-side firmware version must match the cabinet firmware version; mismatch causes silent calibration drift.
12. Failing to plan for 3-8 day rework contingency. If FAT surfaces a batch defect, rework typically takes 3-8 days; buyer schedule must accommodate this without triggering tour-date default penalties.
13. Not signing the FAT closeout document with QC director. Verbal sign-off is not contract evidence; get written sign-off with QC director name, date, and defect log for the shipping record.

12 Questions to Ask a Chinese Outdoor LED Video Wall Manufacturer Before FAT

2. Can you commit in writing to single-batch delivery on my full PO, with cabinet serial-number-to-batch-number mapping at delivery?
3. What is your rain-chamber test protocol during in-line QC (IPX5? IPX6?), what is the sample size, and what is the acceptance criteria?
4. What is your delta-E factory calibration protocol per cabinet, and can I inspect the calibration line during my FAT visit?
5. What is your refresh-rate spec (3,840 Hz? 7,680 Hz?) and what high-speed camera capture verification is available?
6. Can you build a 20-40 cabinet integrated wall configuration on your factory floor during my Day 4 FAT, and can you commit 4-8 hours of stress-content testing?
7. What is your PE-stamped structural drawing package for the cabinet-plus-truss-plus-ballast system, and which jurisdictions is your PE licensed in?
8. What is your gasket / grommet / seal supplier list, and can you commit to a primary supplier for my PO (no substitution to secondary supplier)?
9. What is your salt-spray test coverage for coastal deployments, and can you supplement with a fresh 96-hour salt-spray test if my deployment is coastal?
10. What is your container-load sequence protocol, dunnage plan, and container seal procedure? Can I attend container loading on my Day 5 FAT?
11. What is your rework capability if my FAT surfaces a batch defect, and what is your typical rework schedule (3-8 days)?
12. What is your QC director’s name and background, and can I sign the FAT closeout document directly with them?

FAQ: China LED Video Wall Outdoor Rental Manufacturer FAT

What is FAT (Factory Acceptance Test) and why does it matter for outdoor rental cabinets?

FAT is the pre-shipment physical qualification test that a buyer runs at the manufacturer’s factory in Shenzhen the week before the container is sealed. It matters for outdoor rental cabinets because outdoor deployments face IP-rating stress, UV degradation, salt-spray corrosion, thermal cycling, and wind loading — and datasheet claims on these environmental specs are not the same as verified performance on the specific production batch. FAT is where the buyer closes the gap between claim and verified performance.

How much does a buyer FAT cost?

Typical range USD 24,000-98,000 depending on team size, instrument ownership vs rental, supplementary test-house reports, and rework contingency. Elapsed time 7-14 days end-to-end including travel. For a typical outdoor P4.8 220-cabinet PO of USD 620,000-820,000 FOB Shenzhen, FAT runs 3-12% of PO value and typically pays for itself on any single batch defect discovered.

How many cabinets should I sample at FAT?

Industry standard is 5-10% random sample from the sealed production batch. On a 220-cabinet PO that means 12-22 cabinets. Sampling fewer than 5% is not statistically representative; sampling more than 10% is typically not incremental value unless the batch is already showing defects.

What is the difference between IP65 and IP54 on an outdoor cabinet?

IP65 (dust-tight, protected against water jet) is the typical outdoor rental spec for the cabinet front face where LED modules and gaskets are exposed to wind-driven rain. IP54 (dust-protected, protected against water splash) is the typical spec for the cabinet rear where cable-glands, PSU, and receiver-card enclosures are located. Occasional coastal / marine deployments require IP66 on both faces.

What test-house is best for outdoor rental cabinet certification?

SGS, TUV Rheinland, Bureau Veritas, Intertek, DEKRA, and UL are the internationally recognised test houses with Shenzhen offices. All are typically acceptable for buyer FAT test-report review. Choice typically depends on the target jurisdiction (UL preferred for US; TUV Rheinland preferred for DACH; Bureau Veritas preferred for France / Francophone Africa; Intertek preferred for UK; SGS is broadly acceptable globally).

Can I use a third-party inspection agent instead of flying to Shenzhen?

Yes for lower-value POs (USD 100,000-400,000) and repeat manufacturer relationships. Third-party inspection typically costs 20-60% of buyer FAT. But third-party inspection does not include senior video engineer judgment, PE structural review, or buyer-side calibration verification, so for high-value POs and new manufacturer relationships, buyer FAT is typically the correct choice.

What is delta-E and why does it matter for outdoor cabinets?

Delta-E is a colour-difference metric measuring how far a rendered colour deviates from the reference target. Just-Noticeable-Difference (JND) is delta-E of 2. Broadcast-tier requirement is delta-E under 2 on per-cabinet and under 3 across a wall configuration. Delta-E drift causes visible seam-line colour differences on-camera and is the single biggest determinant of professional-tier outdoor cabinet quality.

What refresh rate should an outdoor rental cabinet have in 2026?

Standard: 3,840 Hz for camera-safe broadcast and touring rental. High-end: 7,680 Hz for XR / virtual production / broadcast studio. Refresh rate below 3,840 Hz shows scan-line beating on-camera at 4K/60p and is not acceptable for professional-tier deployment.

What is the typical outdoor P4.8 cabinet weight and how much can fit in a 40HQ container?

Typical outdoor P4.8 cabinet: 28-36 kg depending on size (typical 500×500 mm or 500×1000 mm). A 40HQ container (76.3 cbm capacity, 26,700 kg payload) typically fits 55-72 cabinets plus road cases, cabling, mounting hardware, and spare-parts kit. Container-load supervision at FAT Day 5 is important to verify no substitution occurs between FAT sign-off and container seal.

What PE license does the manufacturer need for outdoor deployment?

The manufacturer’s PE-stamped structural drawings must match the jurisdiction of intended deployment: US state PE (typically Florida / California / Texas / New York / Nevada for touring routes); EU CEng or Chartered Engineer; UK CEng; Canada P.Eng.; Australia RPEQ. Many Chinese manufacturers offer PE-stamped drawings through partnerships with US-licensed PE firms; verify the PE license is active and current for your target jurisdiction.

What is the typical FAT sign-off document?

Signed FAT closeout by the manufacturer’s QC director listing: PO number, cabinet serial-number range, batch number, cabinet count, defect log (any observed defects and remediation), photograph log reference, test-result log reference, container seal number, container-load sequence photograph reference, and buyer sign-off. This document is the contractual evidence for warranty claims and RMA disputes downstream.

What happens if my FAT surfaces a batch defect?

Standard response: manufacturer proposes remediation plan (typically rework affected cabinets, replace failed grommet / gasket / component, re-test on 15-25% random sample post-rework). Typical rework schedule 3-8 days. Buyer schedule must accommodate this contingency without triggering tour-date default penalties. Cost of remediation typically borne by manufacturer if defect is manufacturer’s responsibility; borne by buyer if defect is due to buyer-supplied component or buyer-side spec change.
