ANSI/ISEA 107-2015, American National Standard for High-Visibility Safety Apparel And Accessories
This standard specifies performance requirements for high-visibility safety apparel and accessory PPE.
For the purpose of this standard, the term “high-visibility safety apparel (HVSA)” shall be used to mean apparel and accessory PPE intended to provide conspicuity to the user in hazardous situations under any light conditions by day and under illumination by vehicle headlights in the dark or other low light conditions.
Performance requirements are included for color, retroreflection, and minimum areas of retroreflective and combined-performance materials, as well as the recommended configuration of the materials. Performance requirements are also provided for the color, physical properties, and minimum areas of background materials used in the construction of HVSA and accessories. Test methods are provided in the standard to ensure that a minimum level of visibility is maintained when garments are subjected to ongoing care procedures. These specifications may prescribe a wide variety of occupational HVSA, but shall not be applied to firefighter turnout gear.
ANSI/ISEA 107-2015 focuses on the following: Design, Requirements for Background and Combined-Performance Retroreflective Materials, Photometric and Physical Performance Requirements for Retroreflective Materials, Care Labeling
* Definitions :
Background material: Colored fluorescent material intended to be highly conspicuous, but not intended to comply with the requirements of this standard for retroreflective material.
Retroreflective material: Material that reflects and returns a relatively high proportion of light in a direction close to the direction from which it came.
Combined-performance material: A retroreflective material that is also a fluorescent material.
High Visibility Safety Apparel (HVSA): Personal protective safety clothing intended to provide conspicuity during both daytime and nighttime, and other low-light condition usage.
High Visibility Accessory: A high-visibility item or items that can help define the human form and, when combined with movement, enhance nighttime conspicuity.
Photometric Performance: The effectiveness of retroreflective material in returning light to its source and measured in terms of coefficient of retroreflection.
