(Specification)Standard Specification for Rigid (Unplasticized) Poly(Vinyl Chloride) (PVC) Soffit
Standard Specification for Rigid (Unplasticized) Poly(Vinyl Chloride) (PVC) Soffit
ABSTRACT
This specification establishes the physical requirements and test methods for extruded single-wall soffits manufactured from rigid (unplasticized) poly(vinyl chloride) (PVC) compounds. The PVC compound when extruded into soffit shall maintain uniform color and be free of any visual surface or structural changes such as peeling, chipping, cracking, flaking, or pitting. Materials shall undergo testing and shall conform accordingly to requirements in terms of dimension (length, width, and thickness), camber, initial impact resistance, coefficient of linear expansion, gloss, deflection, and color.
SCOPE
1.1 This specification establishes requirements and test methods for the materials, dimensions, camber, impact strength, expansion, and appearance of extruded single-wall soffit manufactured from rigid (unplasticized) PVC compound. Methods of indicating compliance with this specification are also provided.
1.2 The use of PVC recycled plastic in this product shall be in accordance with the requirements in Section 4.
1.3 Rigid (unplasticized) poly(vinyl chloride) (PVC) siding is covered in Specification D 3679.
1.4 Soffit produced to this specification shall be installed in accordance with Practice D 4756. Reference shall also be made to the manufacturer's installation instructions for the specific product to be installed.
Note 1—Information with regard to soffit 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 and health practices and determine the applicability of regulatory limitations prior to use.
Note 2—There is no known ISO equivalent to this standard.
