High-Visibility Safety Apparel standard has been improved for 2020

The American National Standard for High-Visibility Safety Apparel (ANSI/ISEA 107) has been updated for 2020.

Companies wishing to represent their products as compliant will be a need to certify and/or recertify background materials, reflective tape, and garments to the 2020 standard.

Vartest is a member of the High Visibility Products Group of the International Safety Equipment Association (ISEA), the organization that created this updated standard. We’re well-positioned to test and offer consultation on the new standard. Contact us for more information or to get started.
