ANSI/ISEA 107-2004: Revised American National Standard for High-Visibility Safety Apparel and Headwear
This standard provides a uniform, authoritative guide for the design, performance specifications, and use of high-visibility and reflective apparel including vests, jackets, bib/jumpsuit coveralls, trousers and harnesses. Garments that meet this standard can be worn 24 hours a day to provide users with a high level of conspicuity through the use of combined fluorescent and retroreflective materials. The revised version of the standard expands the product coverage to include high-visibility headwear. It also contains additional testing procedures for knitted fabrics used as background material, and eliminates tests from the previous edition that added no value.
