How to Verify FR Rainwear Compliance Before You Order: A Sourcing Checklist

Before requesting documentation, confirm which standard applies to the market you’re supplying. FR rainwear sold into different regions must meet different compliance benchmarks — and a valid certificate in one market may carry no weight in another.

• ASTM D6413/D6413M — the primary vertical flame test for North American and Latin American markets. Measures afterflame time, afterglow time, char length, and melting/dripping behavior. See our full guide on what ASTM D6413 tests and how to read the results.
• EN ISO 14116 — the European limited flame spread standard, evaluated at garment level by a Notified Body. Index 1 is the standard performance level for PU-coated FR rainwear. For European buyers, garment-level certification — not fabric testing alone — is the appropriate documentation format.

A one-page summary certificate confirms an outcome. The underlying laboratory report shows you how that outcome was reached — specimen by specimen, direction by direction. For FR rainwear, the detailed report provides meaningful information that the certificate alone cannot.

When reviewing an ASTM D6413 or EN ISO 14116 laboratory report, check for:

A test report only has value if it applies to the actual product being supplied. This is one of the most commonly overlooked verification steps — and one of the most important.

Before approving a supplier’s documentation, cross-check the following between the test report and your purchase order:

• Style or item number — must match exactly, not be a similar style from the same manufacturer
• Fabric composition and coating type — e.g., 100% polyester + PVC coating, stated weight (gsm)
• Production facility — the factory listed on the report should correspond to where your order will be produced
• Test date — recent testing is more meaningful than a report several years old, particularly if there have been any material or process changes

If the product is marketed as both flame-resistant and high-visibility, these two properties require separate documentation. Flame resistance and visibility are evaluated under entirely different standards — compliance with one does not imply anything about the other.

For hi-vis FR rainwear, confirm:

• ANSI/ISEA 107 (Class 2 or Class 3) for North American markets — assessed on the finished garment design, not fabric or tape components alone
• EN ISO 20471 for European markets — part of the garment-level certification package alongside EN ISO 14116, EN 343, and EN ISO 13688

These four standards together form the basis of a complete European garment certification for FR hi-vis rainwear, issued by an accredited Notified Body such as AITEX.

Beyond reviewing the documents themselves, the way a supplier handles documentation requests tells you a great deal about their overall reliability as a manufacturing partner.

A supplier with a strong compliance culture will typically:

• Provide full laboratory reports without hesitation — not just summary certificates
• Be able to explain which test report applies to which product clearly and without confusion
• Keep documentation current and flag any changes in fabric sourcing or production process proactively
• Answer specific technical questions about their test results without deflecting to sales language
