ANSI/ISEA 107-2020
American National Standard for High-Visibility Safety Apparel 

This fifth edition builds on the requirements for designing garments intended to provide enhanced visibility to the worker.  ANSI/ISEA 107-2020 , American National Standard for High-Visibility Safety Apparel continues to present three performance classes of garments based on the number of visible materials and design attributes incorporated into the final configuration and identifies garment types based on expected use settings and work activities being performed.  These are designated as off-road (type O), roadway and temporary traffic control (type R), or public safety activities (type P).

Key updates include the specific criteria for a single-use high-visibility disposable coverall, which is often used in dirty working environments where worker visibility is imperative and introduction a garment’s overall nighttime luminance as an optional reporting characteristics.  Additionally, to emphasize the configurations and design requirements that contribute to the Type-Performance Class designations, previous criteria related to accessories has been removed.  Updates have also been made to the tests methods in an effort to align more closely with other material integrity tests and to recognize current versions used for evaluating the materials

To comply with ANSI/ISEA 107-2020, a garment’s background material and retroreflective or combined-performance material must be tested by an accredited laboratory. The manufacturer of the finished item then verifies that the garment or headwear meets all the requirements of the standard, and provides a Declaration of Conformity for each model.  Examples of test forms and the Declaration of Conformity are included in the standard and located in the resource section below.
