ANSI Z535.1-2017 Page i 2017 National Electrical Manufacturers Association AMERICAN NATIONAL STANDARD Approval of an American National Standard requires verification by The Americ
12、an National Standards Institute, Inc. (ANSI) that the requirements for due process, consensus, and other criteria for approval have been met by the standards developer. An American National Standard implies a consensus of those substantially concerned with its scope and provisions. Consensus is esta
13、blished when, in the judgment of the ANSI Board of Standards Review, substantial agreement has been reached by directly, and materially affected interests. Substantial agreement means much more than a simple majority, but not necessarily unanimity. Consensus requires that all views and objections be
14、 considered and that a concerted effort be made toward their resolution. The existence of an American National Standard does not in any respect preclude anyone, whether s/he has approved the standard or not, from manufacturing, marketing, purchasing, or using products, processes, or procedures not c
15、onforming to the standards. It is intended as a guide to aid the manufacturer, the consumer, and the general public. The American National Standards Institute, Inc., does not develop standards and will in no circumstances give an interpretation of any American National Standard. Moreover, no person
16、shall have the right or authority to issue an interpretation of an American National Standard in the name of the American National Standards Institute, Inc. Requests for interpretations should be addressed to the secretariat or sponsor whose name appears on this title page. CAUTION NOTICE: This Amer

34、ociation Foreword In 1979, the ANSI Z53 Committee on Safety Colors was combined with the ANSI Z35 Committee on Safety Signs to form the ANSI Z535 Committee on Safety Signs and Colors. The Z535 Committee has the following scope: To develop standards for the design, application, and use of signs, colo
35、rs, and symbols intended to identify and warn against specific hazards and for other accident prevention purposes. While the basic mission and fundamental purpose of the ANSI Z535 Committee is to develop, refine, and promote a single, uniform graphic system used for communicating safety and accident
36、 prevention information, the Z535 Committee recognizes that this information can also be effectively communicated using other graphic systems. The Z535 Committee created subcommittees to update the Z53 and Z35 standards and to write new standards. To date, the following six standards comprise the AN
37、SI Z535 series: ANSI Z535.1 Safety Colors ANSI Z53.1-1979 was updated and combined with this standard in 1991 ANSI Z535.2 Environmental and Facility Safety Signs ANSI Z35.1-1972 and Z35.4-1972 were updated and combined into this standard in 1991 ANSI Z535.3 Criteria for Safety Symbols new in 1991 AN
38、SI Z535.4 Product Safety Signs and Labels new in 1991 ANSI Z535.5 Safety Tags and Barricade Tapes (for Temporary Hazards) ANSI Z35.2-1974 was updated and combined with this standard in 1991 ANSI Z535.6 Product Safety Information in Product Manuals, Instructions, and Other Collateral Materials new in
39、 2006 Together, these six standards contain the information needed to specify formats, colors, and symbols for safety signs used in environmental and facility applications, product and product literature applications, and temporary safety tag and barricade tape applications. Published separately is
40、the ANSI Z535 Safety Color Chart. This chart gives the user a sample of each of the safety colors red, orange, yellow, green, blue, purple, white, and black. It also describes each colors ink formulation and closest PANTONE color. This ANSI Z535.1 standard was prepared by the Z535.1 Subcommittee on
41、Safety Colors. The foreword and all annexes are considered to be informative; the body is considered normative. In the vocabulary of writing standards, the word “informative” is meant to convey that the content presented is for informational purposes only and is not considered to be mandatory in nat
42、ure. The word “normative“ is meant to convey that the content is considered to be mandatory or prescriptive. The (R2011) edition of this standard is the eighth revision of the American War Standard, developed at the request of the War Department and approved by the American Standards Association (AS
43、A) on July 16, 1945. The ASA was reconstituted as the USA Standards Institute (USASI) in August 1966, and as the American National Standards Institute (ANSI) in October 1969. Peacetime work on revising the American War Standard containing the Safety Color Code began in 1946 under committee procedure
44、s of the ASA, with the National Safety Council serving as a sponsor of the project. The Sectional Committee on the ANSI Z535.1-2017 Page viii 2017 National Electrical Manufacturers Association (PAT, I cant get the footers to line up with the even pages without messing up the flow of the document) Sa
45、fety Color Code, Z53, reviewed the War Standard and enlarged its application to include the colors orange, blue, and purple. The committee also approved standard definitions and limits for the colors. The revised standard was approved by the ASA on September 11, 1953. In the 1971 revision, the Z53 c
46、ommittee deleted the color blue and modified the application of the color yellow, due to conflicts with other American National Standards. In the fourth revision, a significant step forward was made toward increased safety through uniformity in safety color coding. The safety colors formerly used in
47、 this standard were combined and adjusted to give the best feasible discrimination for observers with either normal or color-deficient (colorblind) vision. For the first time, safety color tolerance charts were available for use with this standard (see Section 8, Reference 17). Each color tolerance
48、chart shows the standard color and six color tolerances illustrating acceptable ranges in hue, value (lightness), and chroma (saturation). Each color tolerance chart also lists the Munsell notation and equivalent Commission Internationale de LEclairage (CIE) specifications (x, y, Y) for each standar
49、d color and tolerance sample. The colors brown, blue, and gray were added, and Table 1 was expanded to include the same information on most of the levels of the Universal Color Language (UCL) for the tolerance samples as for the standard or central sample of each Safety Color. Sections 1 to 6 of the present standard contains material similar to the fourth revision (Z53.1, 1979). The intent of the fifth revision (1991) of the safety color standard was to provide a serie
