Materials and Manufacture4.1 Vinyl Siding:4.1.1 The vinyl siding, exclusive of foam plastic in

38、sulating material, 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 % byvolume. This limitation does not apply to the insulation material.4.1.2 Where rigid PVC recycled pla

39、stic as defined in Guide D7209 is used, the vinyl siding containing the PVC recycled plasticshall meet all of the requirements of Sections 3, 4, and 5.4.1.3 The vinyl siding material, exclusive of insulation material, when tested in accordance with Test Method D635, shall notexceed an average extent

40、 of burn of 4 in. (100 mm), with an average time of burn not to exceed 10 seconds. A minimum samplethickness of 0.035 in. (0.9 mm) is required. (WarningThe flammability testing data, conclusions, and recommendations of TestMethod D635 relate solely to the measurement and description of properties fo

41、r classification of the vinyl siding material inresponse to flame under controlled laboratory conditions and shall not be used for the description or appraisal of the fire hazardof vinyl siding under actual fire conditions.)4.2 Foam Plastic Insulation:4.2.1 The foam plastic insulation shall be made

42、of one of the following materials:4.2.1.1 Expanded polystyrene complying with Specification C578.4.2.1.2 Extruded polystyrene complying with Specification C5784.2.1.3 Polyisocyanurate complying with Specification C591 or Specification C12894.2.2 The foam plastic insulation shall have a Flame Spread

43、Index not greater than 75 and a Smoke Developed Index not greaterthan 450 when tested separately under Test Method E84.4.3 Adhesives:4.3.1 The suitability for outdoor use of an adhesive used to bond the vinyl siding and the insulation, if any, shall be determinedby the following procedure.4.3.1.1 Pr

44、epare a minimum of 10 specimens consisting of two Douglas fir-larch blocks or other appropriate substrates, bondedby the adhesive, in accordance with Test Method C297/C297M. Each block is to be 2.0 inches square. The adhesive shall beapplied and cured in accordance with the adhesive manufacturers in

45、structions.(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 according to the manufa

46、cturers 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 the adhesive.D779

49、ordance with either (a), (b), or (c).(a) For a valid test, the mode of failure for no fewer than 75 % of the specimens shall be cohesive. Only specimens that failedcohesively are counted in the following. The 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 specimens that were subjected to conditioning only.(b) None of five aged specimens fails cohesively under a tensile load less than or equal to 100 psi at a pull rate (crossheadspeed
