Scope*1.1 This specification establishes requirements for insulatedvinyl siding, which is vinyl siding with integral foam plasticinsulating material, where the vinyl sid

3、ing is manufacturedfrom rigid PVC compound. Compliance with this standardrequires insulated vinyl siding to demonstrate a thermal insu-lation value of R-2.0 or greater. Other performance require-ments and test methods addressed by this standard includematerials properties and dimensions, warp, shrin

4、kage, impactstrength, expansion, appearance, thermal distortion resistance,and windload resistance. Methods of indicating compliancewith this specification are also provided.NOTE 1Insulated vinyl siding is composed of two major components:the vinyl siding and the insulating material. It is intended

5、that the vinylsiding portion comply with Specification D3679. Applicable portions ofSpecification D3679 are included in this specification. Additional require-ments that pertain only to the insulation as a separate material, or to thecombination of vinyl siding and insulation as a whole, are also in

6、cluded.For further explanation, see Appendix X1.1.2 Insulated vinyl siding shall be tested with the insulationmaterial in place or removed, as specified in the applicablerequirement or test method.1.3 The use of PVC recycled plastic in this product shall bein accordance with the requirements in Sect

7、ion 4.1.4 Insulated vinyl siding produced to this specificationshall be installed in accordance with Practice D4756. Refer-ence shall also be made to the manufacturers installationinstructions for the specific product to be installed.1.5 The values stated in inch-pound units are to be regardedas sta

Any layers of materials other thanpoly (vinyl chloride) (PVC) compound shall be kept to lessthan 20 % by volume. This limitation does n

39、ccordance with Test Method D635,shall not exceed an average extent of burn of 4 in. (100 mm),with an average time of burn not to exceed 10 seconds. Aminimum sample thickness of 0.035 in. (0.9 mm) is required.(WarningThe flammability testing data, conclusions, andrecommendations of Test Method D635 r

Each block is to be 2.0 inches square. Theadhesive shall be applied and cu

44、red in accordance with theadhesive manufacturers instructions.(1) The material selected for use as the substrate shall becapable of withstanding the accelerated aging described in4.3.1.2 without damage or deterioration of the substrate.NOTE 3Other appropriate substrates, such as metal or plastic, co

45、m-patible with the adhesive according to the manufacturers guidelines, canbe used in place of the Douglas fir-larch blocks. Because in accordancewith 4.3.1.4.1 at least 75 % of samples must fail in a cohesive mode, asubstrate should be selected that is expected to be stronger than theadhesive and wh

46、ich will form a tight bond with the adhesive.4.3.1.2 Subject 50 percent of the specimens to acceleratedaging under Test Method D1183, Test Condition C, for threecycles.The low-temperature portion of the cycle is not requiredto be colder than -40F (-40C) and the relative humidityduring this portion o

47、f the cycle shall not be greater than 10 %RH.4.3.1.3 Condition and test all of the specimens in accor-dance with Test Method C297/C297M.4.3.1.4 Acceptable PerformanceAcceptable performanceof the adhesive is demonstrated by one of the following means:(1) When tested in accordance with 4.3.1.3, the sa

48、mplesdemonstrate performance in accordance with either (a), (b), or(c).(a) For a valid test, the mode of failure for no fewer than75 % of the specimens shall be cohesive. Only specimens thatfailed cohesively are counted in the following. The averageultimate tensile strength of the samples that were

49、subjected toaccelerated aging shall not be less than 80 % of the averageultimate tensile strength of the specimens that were subjectedto conditioning only.(b) None of five aged specimens fails cohesively under atensile load less than or equal to 100 psi at a pull rate(crosshead speed) of 0.02 in./min. Only specimens that failcohesively or do not fail are counted. Specimens that failnon-cohesively under a load at or below 100 psi are discardedand another specimen is tested until five specimens have eitherfailed cohesively, or have not failed at
