Hi-Vis Specs & Standards

ANSI Certified Workwear by Caterpillar

Hi-Vis ANSI Certified Workwear

Hi-Visibility Certifications Defined

The ANSI/ISEA 107 American National Standard for High-Visibility Safety Apparel and Accessories is a voluntary standard with guidelines that provide practical instruction regarding both reflective material and garment design to enhance worker visibility.  ANSI/ISEA 107 presents three performance classes of garments and identifies garment types based on expected use settings and work activities being performed.

EN ISO 20471 is the European standard.


Type R offers a Performance Class 2 and Class 3 - garments specifically designed for use on roadways, and is often the choice of other construction and transportation applications due to the high presence of moving vehicles and equipment.

ANSI Class 2 & 3

ANSI certifications are designed for garments intended for activities where greater visibility is necessary during inclement weather. It also covers workers who perform tasks that divert their attention from approaching traffic or puts them in close proximity to vehicles traveling 25 mph or higher.

ANSI Class E 

Applies to retro-reflective equipped pants or shorts, designed to be worn in combination with either Class 2 or Class 3 tops. When worn in this manner, the ensemble is rated as Performance Class 3. When worn alone they do not meet any of the ANSI class requirements.
