43、2 Thermogravimetric test The test shall be carried out in accordance with EN ISO 11358 on the uncured or wet sealant, between 35 C to 900 C, temperature slope 10 C/min, non-oxidative condition (e.g. nitrogen). A single sample shall be used for this test. A single specimen may be tested and there sha
44、ll be no significant difference between the reference curve and derivative (profile). In the case of multi-component sealant, each component shall be evaluated (if relevant). 4.1.3 Specific Gravity test The determination of the specific gravity shall be in accordance with EN ISO 1183-1:2004, on the
45、uncured or wet sealant, using Method A or Method B, depending on the type of sealant under test. The testing temperature shall be (23 2) C. At least three samples shall be tested. The method used and the mean value, recorded to two decimal places, shall be declared. The tolerance of the declared val
46、ues shall be within 5 %. 4.1.4 Hardness (indentation) test (Shore Hardness) The determination of the indentation hardness shall be in accordance with EN ISO 868. The test shall be performed on the cured or dried sealant. The exact conditions of test shall be defined by the manufacturer, i.e. thickne
