ASTM C1635-16 在固定范围内密封剂粘附/粘结特性评价的标准试验方法

5.1 In any sealant application, the sealant must be capable of maintaining an adhesive bond to the substrate when held in strain for its intended service life. 5.2 This test method is an indicator of a sealant’s ability to adhere under strain to a given substrate. 5.3 The default test strain is the movement ability of the sealant as designated by the manufacturer. The default joint configuration is 12.7 × 12.7 × 50.8 mm (1/2 × 1/2 × 2 in.). Other strains and joint configurations may be used and reported as noted in Section 8 and Table 1. 1.1 This test method describes a laboratory procedure for measuring the adhesion/cohesion properties of a sealant when subjected to tensile loads resulting from an applied specified strain. The adhesion/cohesion properties are evaluated before, during, and after water immersion. 1.2 This test method examines the adhesive and cohesive performance of a sealant on a specified substrate at a strain equivalent to a multiple of the strain/movement capability designated by the manufacturer for the given sealant per Specification C920. 1.3 The values stated in SI (metric) units are to be regarded as the standard. The inch values given in parentheses are for information only. 1.4 This standard does not purport to address all of the safety concerns, if any associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. 1.5 Comparable Test:  1.5.1 ISO 10590, Building construction - Jointing products - Sealants - Determination of adhesion/cohesion properties at maintained extension after immersion in water 1.5.2 ISO 8340, Building construction - Jointing products - Sealants - Determination of tensile properties at maintained extension

ASTM F36-15 衬垫材料的可压缩性和复原性的标准试验方法

1.1 This test method covers determination of the short-time compressibility and recovery at room temperature of sheet-gasket materials, form-in-place gaskets, and in certain cases, gaskets cut from sheets. It is not intended as a test for compressibility under prolonged stress application, generally referred to as “creep,” or for recovery following such prolonged stress application, the inverse of which is generally referred to as “compression set.” Also, it is not intended for tests at other than room temperature. A resiliency characteristic (the amount recovered expressed as a percentage of the compressed thickness) may also be calculated from the test data where desired. 1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only. 1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
