ISEA 107-2020 PDF Download

The American National Standard for High-Visibility Safety Apparel, known as ANSI/ISEA 107-2020, establishes guidelines for the design, testing, performance, and labeling of high-visibility safety apparel. The purpose of this standard is to enhance the visibility of the wearer in various working environments. The standard categorizes garments into Types and Performance Classes based on their intended use and the level of visibility materials and design elements incorporated into the garment.

One notable update in the 2020 version of the standard is the inclusion of criteria for single-use high-visibility disposable coveralls. These coveralls are designed for use in dirty working environments where worker visibility is crucial. Additionally, the standard now includes the option to report a garment's nighttime luminance, which measures its visibility in low-light conditions.

The standard has also undergone updates to align its testing methods with other material tests and reflect updated protocols. These updates aim to improve consistency and accuracy in assessing the performance of high-visibility safety apparel.
