Significance and Use
5.1 Plastic composite materials for use as deck boards, stair treads, guards or handrails are evaluated in accordance with Test Method to comply with building or residential code requirements. This Practice describes specimen mounting procedures for such materials.
5.2 The material to be tested shall be representative of the materials used in actual field installations.
Note 2: Test Method assesses the comparative burning behavior of building materials. Thus, this practice addresses specimen preparation and mounting of materials at use thickness, with full width tunnel coverage.
5.3 The limitations for this procedure are those associated with Test Method .
1.1 This practice describes a procedure for specimen preparation and mounting when testing plastic composite materials for use as deck boards, stair treads, guards or handrails to assess flame spread index as a surface burning characteristic using Test Method .
1.2 This practice applies to plastic composite materials, including plastic lumber and wood-plastic composites. The test specimens shall be self-supporting or held in place by added supports along the test surface, in accordance with Annex A4 of Test Method .
1.3 This practice does not provide pass/fail criteria that can be used as a regulatory tool.
1.4 This practice is applicable to (a) materials that are self-supporting and (b) materials that are not self-supporting but where the test specimen is held in place by added supports throughout the test duration without such severe sagging that it interferes with the effect of the gas flame on the test specimen.
Note 1: Paragraph reflects requirements contained in plastic lumber specifications.
1.5 Use the values stated in inch-pound units as the standard in referee decisions. The values in the SI system of units are given in parentheses, for information only; see for further details.
1.6 This fire standard cannot be used to provide quantitative measures.
1.7 Fire testing of products and materials is inherently hazardous and adequate safeguards for personnel and property shall be employed in conducting these tests. Fire testing involves hazardous materials, operations and equipment.
1.8 This practice gives instructions on specimen preparation and mounting but the fire-test-response method shall be conducted in accordance with Test Method . See also Section for information on operator safety.
1.9 The text of this practice references notes and footnotes which provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered requirements of the standard.
1.10 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.
1.11 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.
