1.1 This terminology covers terms, related definitions, and descriptions of terms used or likely to be used in fire-test-response standards, fire-hazard-assessment standards, and fire-risk-assessment standards. Definitions of terms are special-purpose definitions that are consistent with the standard definitions but are written to ensure that a specific fire-test-response standard, fire-hazard-assessment standard, or fire-risk-assessment standard is properly understood and precisely interpreted. Note 1: For additional information, refer to ASTM Policy on Fire Standards. 2 1.2 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.3 This fire standard cannot be used to provide quantitative measures. 1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. ====== Significance And Use ====== 3.1 Definitions —Terms and related definitions given in Section 4 are intended for use uniformly and consistently in all fire test standards and in all fire-test-response standards, fire-hazard-assessment standards, and fire-risk-assessment standards in which they appear. 3.2 Definitions of Terms Specific to This Standard: 3.2.1 As indicated in Section 4 , terms and their definitions are intended to provide a precise understanding and interpretation of fire-test-response standards, fire-hazard-assessment standards, and fire-risk-assessment standards in which they appear. 3.2.2 A specific definition of a given term is applicable to the standard or standards in which the term is described and used. 3.2.3 Different definitions of the same term, appearing respectively in two or more standards, are acceptable provided each one is consistent with and not in conflict with the standard definition for the same term, that is, concept. 3.2.4 Each standard in which a term is used in a manner specially defined (see 1.1 and Section 5) shall list the term and its description under the subheading, Definitions of Terms. 3.3 Definitions for some terms associated with fire issues and not included in Terminology E176 are found in ISO 13943. When discrepancies exist, the definition in Terminology E176 shall prevail.
