ANSI ISEA 107:2020 pdf download.American National Standard for High-Visibility Safety Apparel.
ANSI ISEA 107 specifies performance requirements for high-visibility safety apparel. For the purpose of this standard, the term “highvisibility safety apparel (HVSA)” shall be used to mean apparel 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, physical properties and minimum areas of background, retroreflective and combined-performance materials, as well as the recommended configuration of the materials. 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.
2 Purpose
Conspicuity is enhanced by high contrast between the garment and the ambient background against which it is seen. This standard provides performance requirements for conspicuous materials to be used in HVSA and specifies minimum amounts of background, retroreflective and combined-performance materials, colors and placement of materials for garments, and supplemental items used to enhance the visibility and safety of workers. Performance Class guidelines are identified with corresponding recommendations for selection based on worker risk hazards, such as complex backgrounds, vehicular traffic and speeds encountered.
3 Definitions
Accredited laboratory: A laboratory having a certificate of accreditation meeting the requirements ISO/IEC 17025:2017, General requirements for the competence of testing and calibration laboratories for the collection and analysis of data within the parameters of this standard.
Background material: Colored fluorescent material intended to be highly conspicuous in daytime and dawn/dusk conditions, but not intended to comply with the requirements of this standard for retroreflective material.
Band: A strip or stripe that contrasts with the adjacent material in color, texture, material or function.
Combined-performance material: Material that exhibits both background and retroreflective properties.
Conspicuity: The characteristics of an object influencing the probability that it will come to the attention of an observer, especially in a complex environment which has competing objects.
Declaration of conformity: A statement by the manufacturer or supplier, based on a decision following review, that fulfillment of the requirements specified in this standard has been demonstrated. (Appendix E3)
Flame resistance: The property of a material whereby flaming combustion is prevented, terminated or inhibited following application of a flaming or non-flaming source of ignition with or without subsequent removal of the ignition source.
Fluorescent material: Material that instantaneously emits optical radiation within the visible range at wavelengths longer than absorbed and for which emission ceases upon removal of the source of irradiation. These materials enhance daytime visibility, especially during dawn and dusk.ANSI ISEA 107 pdf download.
