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

39、e adhesive.4.3.1.2 Subject 50 percent of the samples to accelerated aging under Test Method D1183, Test Condition C, for three cycles.The low-temperature portion of the cycle is not required to be colder than -40F (-40C) and the relative humidity during thisportion of the cycle shall not be greater

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

43、eparately, under 5.2.55.2.4.4.4 Insulated Vinyl Siding:4.4.1 Insulated vinyl siding shall not contain elemental lead (Pb) or compounds of that material other than traces incidental toraw materials or the manufacturing process. This limitation applies to both PVC substrate and to any cap or film mate

44、rial, as wellas the insulation material. Compliance with this requirement shall be demonstrated by one of the methods in 6.16.5. Physical Requirements5.1 Requirements Applicable to Vinyl SidingThe provisions of 5.1.1-5.1.8 apply only to the vinyl siding, exclusive of anyinsulation material. Where ne

45、cessary to perform testing, the insulation material shall be removed.5.1.1 Length and WidthThe nominal length and width of the vinyl siding shall be as agreed upon between the purchaser andthe seller. The actual length shall not be less than 14 in. (6.4 mm) of the nominal length and the actual width

46、 shall be within 6116in. (1.6 mm) of the nominal width when measured in accordance with 6.3 and 6.4.5.1.2 ThicknessThese requirements pertain only to measurements of the portions of the vinyl siding that are exposed afterinstallation of the panel, measured in accordance with the procedure in 6.5. Th
