1.1 This specification establishes requirements for vinyl siding with integral foam plastic backing, where the siding is manufactured from rigid PVC compound. Performance requirements and test methods addressed by this standard include materials properties and dimensions, warp, shrinkage, impact strength, expansion, appearance, and wind load resistance. Methods of indicating compliance with this specification are also provided. NOTE 1—Backed vinyl siding is composed of two major components: the siding and the backing. It is intended that the siding portion comply with Specification D3679. Applicable portions of Specification D3679 are included in this specification. Additional requirements that pertain only to the backing as a separate material, or to the combination of siding and backing as a whole, are also included.
1.2 Backed vinyl siding shall be tested with the backing material in place or removed, as specified in the applicable requirement or test method.
1.3 The use of PVC recycled plastic in this product shall be in accordance with the requirements in Section 4.
1.4 Rigid PVC soffit is covered in Specification D4477.
1.5 Siding produced to this specification shall be installed in accordance with Practice D4756. Reference shall also be made to the manufacturer’s installation instructions for the specific product to be installed. NOTE 2—Information with regard to siding maintenance shall be obtained from the manufacturer.
1.6 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.
1.7 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. NOTE 3—There is no known ISO equivalent to this standard.
1.8 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.
