1. Scope
1.1 This specification establishes requirements for vinyl siding with integral foam plastic backing when the siding is manufactured from rigid PVC compound. Performance requirements and test methods addressed by this specification include materials properties and dimensions, warp, shrinkage, impact strength, expansion, appearance, and windload 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 D 3679. Applicable portions of Specification D 3679 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 D 4477. 1.5 Siding produced to this specification shall be installed in accordance with Practice D 4756. Reference shall also be made to the manufacturers installation instructions for the specific product to be installed. NOTE 2Information 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 the standard. The SI units given in parentheses are for information purposes only. 1.7 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 and health practices and determine the applicability of regulatory limitations prior to use. NOTE 3There is no known ISO equivalent to this standard.
Vinyl siding with integral backing has been available for a number of years and has been nominally covered under D 3679. Specific requirements for the foam backing material and the performance of the combiantion of siding and backing are needed and are provided by this separate standard. It is expected that this specification will be used by manufacturers of the product and product certification programs and be referenced by building codes.
