ASTM F1506 has been updated for 2015.
This is the clothing standard used in OSHA 1910.269 and NFPA 70E. The standard is usually updated every few years. The newest version includes labeling changes:
- Clarification on Tracking ID to assure a name brand fabric does not change without the end user being able to know (most important if you have done layering tests)
- Requirement to include a ‘Fabric Identifier’ which provides the fabric producer’s name and style number/fabric name. Alphanumeric or similar designations are permitted as a unique ID as long as they are distinct to the producer and traceable to manufacturing and performance information (test results).
