ANSI/ISEA 107-2010: 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. Though the 2010 revision does not change the long-standing requirements for compliant garments with respect to classification and color, it does address important issues for the wearer related to flame-resistance and use during rainfall.
