Standard Practice for Intumescent Coatings
5.1 This practice is intended for use by material specifiers, general contractors, applicators, or any individual or group requiring information regarding the application of intumescent coatings to provide a fire resistance rating to structural steel.
5.2 This practice is not intended to replace the manufacturer’s application instructions.
1.1 This practice provides architects, specifiers and building owners various consensus recommendations to specify industry’s best practices for intumescent coatings.
1.2 This practice covers the best practice for the following:
1.2.1 The manufacturing, testing, labeling, transportation, delivery, and storage, including shelf life, of intumescent coatings.
1.2.2 The application of the intumescent coatings to structural steel for the purposes of providing fire resistance.
1.2.3 The inspection, including safety and equipment, of intumescent coatings during and after the application.
1.3 Standard Practice—This practice offers a set of instructions for performing one or more specific operations. This document cannot replace education or experience and should be used in conjunction with professional judgment. Not all aspects of this practice may be applicable in all circumstances. This ASTM standard is not intended to represent or replace the standard of care by which the adequacy of a given professional service must be judged, nor should this document be applied without consideration of a project’s many unique aspects. The word “Standard” in the title means only that the document has been approved through the ASTM consensus process.
1.4 The text of this standard references notes and footnotes which provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of the standard.
1.5 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
1.6 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.
Note 1: This practice references fire-test-response standards and may involve hazardous tasks. Therefore, the following caveats are also referenced. This practice references tests used to measure and describe the response of materials, products, or assemblies to heat and flame under controlled conditions, but does not by itself incorporate all factors required for fire hazard or fire risk assessment of the materials, products, or assemblies under actual fire conditions. This practice references tests used to predict or provide a quantitative measure of the fire hazard from a specified set of fire conditions involving specific materials, products, or assemblies. This assessment does not necessarily predict the hazard of actual fires which involve conditions other than those assumed in the analysis. This practice references tests used to determine certain fire-test responses of materials, products, or assemblies to heat and flame under controlled conditions by using results obtained from fire-test-response standards. The results obtained from using this practice do not, by themselves, constitute measures of fire hazard or fire risk. Fire testing is inherently hazardous. Adequate safeguards for personnel and property shall be employed in conducting these tests.
1.7 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.
