Significance and Use
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 and health practices and determine the applicability of regulatory limitations prior to use.
