NEMA - ANSI Z535.1
|Publication Date:||1 January 2017|
This standard provides a system for specifying safety colors, in terms of Munsell notations, CIE colorimetric data, defined chromaticity regions, and color formulas for each ANSI and ISO safety color used on safety signs, labels, and tags. It is beyond the scope of this standard to provide in-depth instructions for color measurement. It is beyond the scope of this standard to address the color of safety sign, label or tag substrates.
The purpose of this standard is to:
a. implement a uniform system for specifying safety colors;
b. include safety color formulas for a variety of applications and media for specifying ANSI and ISO Safety Colors, (Annex C);
c. harmonize with safety colors specified in the Code of Federal Regulations, 49 CFR, §172.407 (Subpart E), (Tables 1-3), 49 CFR, §172.407 Label Specifications (5); and
d. harmonize with ISO 3864-4, Graphical symbols-Safety colours and safety signs-Part 4: Colorimetric and photometric properties of safety sign materials, (Annex D). These colors are specified in order to facilitate compliance with ISO safety colors.
