Key takeaways EU Digital Product Passport planning for textiles highlighted the need for machine-readable product data and verifiable test evidence.   European Parliament AATCC issued a 2025 update to its Manual, and ISO released new methods covering antifungal activity and nonwovens mechanical penetration. Labs should refresh SOPs and control plans.   ISO+3aatcc.org+3aatcc.org+3 Certification and chemical management tightened. OEKO-TEX announced 2025 regulation changes. ZDHC’s MRSL...

Key takeaways Anchor your workflow to recognised methods. Use IWTO-47  for wool diameter and IWTO-62  for length and diameter in tops and slivers for traceable results.   member.iwto.org +1 Build your quality system around ISO/IEC 17025  and report measurement uncertainty  using the GUM. This improves confidence and comparability.   ISO+1 Set calibration intervals based on risk, stability and use. NIST  does not mandate a single fixed interval.   NIST Use Interwoollabs IH Standards  for OFDA...

Key takeaways Accurate, rapid fibre data is foundational for circular fashion. It enables sorting, blending and verification across recycled and virgin inputs.   Textile Exchange OFDA2000 and OFDA4000 provide fast, standards-aligned measurements that help reduce rework and off-spec production.   OFDA+1 Recognised methods such as IWTO-47, IWTO-62 and ISO 137 support credible quality documentation and sustainability claims.   member.iwto.org +2OFDA+2 Recycled streams are variable.
