Summary of Test Meth
7、od4.1 This test method consists of testing two RCPS sectionsbonded by adhesive and allowed to set for 24 h. Beforeevaluation, the degree of cavitation is measured and recorded.5. Significance and Use5.1 Rigid foam such as RCPS is used in the buildingconstruction industry. Because it is sensitive to
8、certain compo-nents contained in adhesives which cause it to dissolve, it isimportant to have a test method to determine whether anadhesive is compatible with RCPS foam. This test methodwould help the end user decide which adhesive to use withRCPS foam by quantitatively measuring the amount of cavi-
9、tation formed by the components contained in the adhesive.6. Apparatus6.1 Circular Template, with an inside diameter of 25 mm(1.0 in.) and a depth of 6 mm (14 in.).6.2 Circulating Air Oven, for elevated temperature testing,capable of being held at 40 6 1C (104 6 2F).7. Materials7.1 For the test, use
10、 Type IV RCPS foam with a nominalthickness of 25 mm (1.0 in.).7.2 If another type is used, record the type, thickness anddensity.8. Conditioning8.1 Unless otherwise agreed upon by the purchaser and themanufacturer, condition the test specimen and adhesive 24 hprior to testing at 23 6 1C (73 6 2F) an
