ASTM D7254-21

Standard Specification for Polypropylene (PP) Siding

ABSTRACT
This specification establishes requirements and test methods for materials, impact strength, appearance, surface flame spread, and windload resistance of siding products manufactured from polypropylene material. The use of polypropylene recycled plastic in this product shall conform to the specified requirements. The siding shall be made principally of polypropylene compound, prepared from polypropylene homopolymer or copolymer. The polypropylene compound shall be compounded so as to provide the heat stability and weather exposure stability required for the siding market application.
SCOPE
1.1 This specification establishes requirements and test methods for materials, impact strength, appearance, surface flame spread, and wind load resistance of siding products manufactured from polypropylene material. Methods of indicating compliance with this specification are also provided.  
1.2 The use of polypropylene recycled plastic in this product shall be in accordance with the requirements in Section 4.  
1.3 Siding produced to this specification shall be installed in accordance with manufacturer’s installation instructions for the specific product to be installed.
Note 1: Information with regard to siding maintenance shall be obtained from the manufacturer.  
1.4 The values stated in inch-pound units are to be regarded as the standard. The SI units given in parentheses are for information purposes only.  
1.5 The following precautionary caveat pertains to the test method portion only, Section 6 of this specification: 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 2: There is no known ISO equivalent to this standard.  
1.6 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.
