CIRCUDOWN / STANDARDS, TESTING & CERTIFICATION
Specifications define the material. Test methods describe how it is measured. Certification addresses a stated assurance scope. Laboratories carry out the assigned tests.
| Category | Purpose | Examples to discuss |
|---|---|---|
| Product specification | What must the material meet? | Composition, tolerances and agreed acceptance limits |
| Test method | How will it be measured? | Relevant EN, JIS, USA-2000, KS, GB/T, QB/T or CNS references |
| Certification system | What claim and supply-chain scope is covered? | GRS; OEKO-TEX STANDARD 100; RDS has a distinct scope |
| Third-party laboratory | Who will perform the assigned tests? | IDFL, SGS, QTEC, Guangjian |
Buyer guide
Buying GRS recycled down requires more than a supplier certificate. Verify the certified entity and relevant scope, define the recycled-content requirement, and establish the transaction evidence for the goods being purchased. Separately agree the down specification and performance tests: GRS certification is not a fill power or warmth rating.

Certification
OEKO-TEX STANDARD 100 concerns testing textiles for harmful substances. It should not be used as proof of recycled origin, fill power or complete environmental performance.

Specifications & methods
Use the exact European specification and test method references required by the product and market. “EN standard” alone is not a complete purchase specification.

Specifications & methods
USA-2000 can be discussed as part of the material brief, but a US-market order needs explicit composition, testing and labeling requirements.

Third-party testing
IDFL is a third-party testing organization. An IDFL report documents testing of an identified sample; it is not automatically a certification of every lot or product supplied by a manufacturer.
