Standard Specification for Rigid Poly(Vinyl Chloride) (PVC) Siding
ABSTRACT
This specification establishes requirements and test methods for the materials, dimensions, warp, shrinkage, impact strength, expansion, appearance, and windload resistance of extruded single-wall siding manufactured from rigid (unplasticized) PVC compound. The siding shall be made of one or more layers of poly(vinyl chloride) (PVC) compound. Any layers of materials other than poly (vinyl chloride) (PVC) compound shall be kept to less than 20% by volume. The PVC compound when extruded into siding shall maintain uniform color and be free of any visual surface or structural changes, such as peeling, chipping, cracking, flaking, or pitting. The PVC compound shall be compounded so as to provide the heat stability and weather exposure stability required for the siding market application. PVC siding shall not contain elemental lead (Pb) or compounds of that material other than traces incidental to raw materials or the manufacturing process. This limitation applies to both PVC substrate and to any cap or film material. Materials shall be tested and the individual grades shall conform to specified values of length and width, thickness, camber, heat shrinkage, impact resistance, coefficient of linear expansion, gloss, surface distortion, color, weathering, windload resistance, and nail slot allowance for thermal expansion.
SCOPE
1.1 This specification establishes requirements and test methods for the materials, dimensions, warp, shrinkage, impact strength, expansion, appearance, and wind load resistance of extruded single-wall siding manufactured from rigid (unplasticized) PVC compound. Methods of indicating compliance with this specification are also provided.
1.2 The use PVC recycled plastic in this product shall be in accordance with the requirements in Section 4.
1.3 Rigid (unplasticized) PVC soffit is covered in Specification D4477.
1.4 Siding produced to this specification shall be installed in accordance with the 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.
1.5 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 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.
1.7 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.
