Flammability Sample from Shipped Lot Audit with AI Vision

By David Cook on October 29, 2026

flammability-sample-shipped-lot-audit-ai

A flammability report is only as good as the fabric it describes. If the swatch the lab burned came from a strike-off, an early roll or a lot that was later re-dyed, the report says little about the goods on the truck. When CPSC or a retailer asks for proof, legal teams need to show the sample came from the production that shipped. AI vision records each sample cut, ties it to the ERP lot and the lab report, and holds any shipment whose evidence does not match. See the full chain on real roll goods in a sample traceability demo.

FLAMMABILITY EVIDENCE · SAMPLE TO SHIPMENT

Prove the Burn-Test Swatch Came From the Lot You Shipped

iFactory Sample-Cut Vision Capture photographs every flammability sample at the cutting bench with its roll, lot, position, time and operator. The Shipped-Lot Compliance Link then checks each ASN against that record and the lab report, and holds the shipment when they disagree.

Which Products a Federal Flammability Rule Actually Covers

The Flammable Fabrics Act is enforced through product-specific standards in 16 CFR, and each one has its own scope. Clothing, children's sleepwear, carpets and rugs, mattresses and upholstered furniture are covered. Many other home textiles are not. Before building any sample program, confirm which rule, if any, applies to each line. Map your product lines to these parts with our compliance support team.

Not every home textile has a federal rule

No CPSC flammability standard currently applies to sheets, blankets, comforters, pillows, towels or curtains. Retailer specifications, voluntary standards and state laws may still ask for tests, so treat those as contract or state duties, not federal ones.

WHERE THE CHAIN BREAKS

Four Ways a Passing Report Ends Up Describing the Wrong Fabric

Most gaps are not fraud. They come from normal mill habits: testing early to save time, reusing a report across lots, or finishing a lot again after the test. Each one leaves a valid-looking report that no longer matches the goods. Walk through your own sampling habits in a sample program review.

01
Strike-off or lab dip sampleTested before bulk production, so it shows the design, not the run
02
One report, many lotsA report from lot A is filed against lots B and C with no link back
03
Re-dye or re-finishThe lot is dyed or finished again after the sample was cut
04
Wrong roll at the benchA roll from a neighbouring lot is cut because the tags look alike
SAMPLE CUT TRACEABILITY

What the Camera Records at the Cutting Bench

An overhead camera watches the sample bench. When the operator scans the roll and cuts, the system saves a photo of the cut with the roll tag in frame and attaches the facts a reviewer would ask for later. Nothing is typed from memory. Our support team can show where it meets your current lab request form.

PhotoCut in progress, roll tag readable
Lot IDFrom the roll barcode, checked in ERP

Answer a Records Request in Minutes, Not Days

When counsel asks which sample supports a shipment, the answer comes back with the photo, the roll, the report and the ASN in one place. No digging through lab folders.

FLAMMABILITY VISION SYSTEM LIMITS

Vision Documents the Cut. The Lab Proves the Result.

The camera never tests flammability. It records where and when a sample was cut and links it to the lot. Whether the fabric passes is decided by the test, run to the CFR method by the lab you use. For children's products, that means a CPSC-accepted third-party lab. The workflow joins the two records so neither stands alone. Review the hand-off with our vision engineers.

THE CAMERA DOES NOT
  • Burn, measure or grade any specimen
  • Judge whether a fabric is Class 1 under Part 1610
  • Know whether a finish changed the burn behaviour
  • Replace the lab report or the certificate
VISION AND THE WORKFLOW DO
  • Prove which roll and lot the sample came from
  • Time-stamp the cut against the production unit
  • Match the lab report's sample ID to the cut record
  • Hold any ASN whose lot has no valid match
SHIPPED LOT AUDIT

Five Links From Swatch to Shipment

Each link is a record that already exists somewhere in the plant. The gap is that nobody joins them until an inquiry arrives. iFactory joins them as the goods move, so the chain is complete before the truck leaves. Connect your ERP and lab data with our integration team.

FLAMMABILITY SAMPLE AUDIT FLAGS

Five Mismatches That Hold a Shipment

Each flag is a rule your legal and quality teams agree before go-live. A flag holds the ASN, names the gap and sends it to the person who can close it. Some need a new sample. Others need only a corrected record. Agree your flag rules in a rules session.

LOT
Sample lot is not the shipped lotThe ASN lot has no cut record of its own
AGE
Sample older than the production unitCut before the unit's first roll was made, such as a strike-off
DYE
Re-dye or re-finish after the cutReworked sleepwear fabric must be tested again. Set your own rule for other lines
RPT
Report missing or IDs disagreeNo lab report yet, or its sample ID does not match the cut
FPU
Sleepwear unit too large for its samplesMore yardage than the unit limit with only one sample set
SLEEPWEAR PRODUCTION UNITS

Worked Example: How Many Samples a Sleepwear Order Needs

Children's sleepwear is where the CFR is most specific about sampling. Under normal sampling a fabric production unit can be up to 5,000 linear yards and is tested with one sample from each end. A garment production unit can be up to 500 dozen garments. The order sizes below are assumed, and the unit limits come from CPSC's sleepwear test manual. Check your own plan with our support team.

Sleepwear fabric ordered13,200 linear yards, assumed
Fabric production units at 5,000 yards max5,000 + 5,000 + 3,200 = 3 units
Fabric samples, 2 per unit3 × 2 = 6 samples, 30 specimens
Garments of one style9,000, assumed
Garment units at 500 dozen (6,000) max9,000 ÷ 6,000 = 1.5, so 2 units
Cut records the system expects6 fabric + 6 garment samples = 12

Garment units use 3 samples each under normal sampling, so 2 units need 6. After a rejected fabric unit, tightened sampling adds a third sample from a middle piece of each unit, and the expected count rises with it.

RECORD RETENTION

How Long Each Rule Says to Keep the Evidence

Retention differs by part, and the clock does not always start on the test date. The system keeps each cut record, photo and report for the longest period that applies to the product line, plus any margin your counsel adds. Set retention per line in a records planning call.

3 yrs
Part 1610 guarantiesFrom the date of the tests, including a sample of the fabric tested

FREQUENTLY ASKED QUESTIONS

What Textile Legal Teams Ask About Flammability Sample Audits

Does iFactory test fabric flammability?
No. The test is run by a laboratory to the method in the relevant CFR part. For children's products it must be a CPSC-accepted third-party lab. iFactory records where the sample came from and links it to the lot and the shipment, so the lab result can be shown to describe the goods that shipped.
Which home textiles have a federal flammability rule?
Carpets and rugs (Parts 1630 and 1631), mattresses and mattress pads (Part 1632), mattress sets (Part 1633) and upholstered seating (Part 1640). Sheets, blankets, comforters, pillows, towels and curtains have no CPSC flammability standard today. To see how the system handles a mixed product range, book a 30-minute walkthrough.
Does 16 CFR 1610 apply to bedding?
No. Part 1610 covers textiles used in clothing. Bedding is not clothing, and Part 1640 also excludes bedding products. Children's sleepwear falls under Parts 1615 and 1616, with tight-fitting sleepwear tested under Part 1610 instead.
How long do we keep sample and test records?
It depends on the part. Part 1610 guaranty records run 3 years from the tests, Part 1632 records 3 years, and Part 1633 records last while the prototype is in production plus 3 years. Our support team can set retention for each of your lines.
What counts as a mismatch?
The default flags are a sample from a different lot, a sample older than its production unit, a re-dye or re-finish after the cut, a missing or mismatched lab report and an oversized sleepwear unit. Your legal team signs off each rule. You can see each flag raised on a live dock before go-live.
How should a textile legal team start?
Pick the product line with the most specific rule, often children's sleepwear or rugs. Put one camera over its sample bench, link its ERP lots and run in shadow mode for a few weeks while legal reviews every flag. Then switch on dock holds. Plan that first line with our team.
