Scope Scope*1.1 This specification establishes requirements for insulated vinyl siding, which is vinyl siding with integral foam pl
3、asticinsulating material, where the vinyl siding is manufactured from rigid PVC compound. Compliance with this standard requiresinsulated vinyl siding to demonstrate a thermal insulation value of R-2.0 or greater. Other performance requirements and testmethods addressed by this standard include mate
4、rials properties and dimensions, warp, shrinkage, impact strength, expansion,appearance, thermal distortion resistance, and windload resistance. Methods of indicating compliance with this specification arealso provided.NOTE 1Insulated vinyl siding is composed of two major components: the vinyl sidin
5、g and the insulating material. It is intended that the vinyl sidingportion comply with Specification D3679. Applicable portions of Specification D3679 are included in this specification. Additional requirements thatpertain only to the insulation as a separate material, or to the combination of vinyl
6、 siding and insulation as a whole, are also included.

7、l be in accordance with the requirements in Section 4.1.4 Insulated vinyl siding produced to this specification shall be installed in accordance with Practice D4756. Reference shallalso be made to the manufacturers installation instructions for the specific product to be installed.1.5 The values sta
8、ted in inch-pound units are to be regarded as standard. The values given in parentheses are mathematicalconversions to SI units that are provided for information only and are not considered standard.1.6 This standard does not purport to address all of the safety concerns, if any, associated with its
9、 use. It is the responsibilityof the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatorylimitations prior to use.NOTE 2There is no known ISO equivalent to this standard.2.

36、cedure.4.3.1.1 Prepare a minimum of 10 samples consisting of two Douglas fir-larch blocks or other appropriate substrates, bonded bythe adhesive, in accordance with Test Method C297/C297M. Each block is to be 2.0 inches square. The adhesive shall be appliedand cured in accordance with the adhesive m
37、anufacturers instructions.(1) The material selected for use as the substrate shall be capable of withstanding the accelerated aging described in 4.3.1.2without damage or deterioration of the substrate.NOTE 3Other appropriate substrates, such as metal or plastic, compatible with the adhesive accordin
38、g to the manufacturers guidelines, can be usedin place of the Douglas fir-larch blocks. Because in accordance with 4.3.1.4.1 at least 75 % of samples must fail in a cohesive mode, a substrate shouldbe selected that is expected to be stronger than the adhesive and which will form a tight bond with th

40、than 10 % RH.4.3.1.3 Condition and test all of the samples in accordance with Test Method C297/C297M.4.3.1.4 Acceptable Performance:(1) For a valid test, the mode of failure for no fewer than 75 % of the samples shall be cohesive. Only samples that failedcohesively are counted in the following. The
41、average ultimate tensile strength of the samples that were subjected to acceleratedaging shall not be less than 80 % of the average ultimate tensile strength of the samples that were subjected to conditioning only.(2) As an alternative, adhesives that are covered by a current report, issued by an ag
