SIST EN 15651-1:2017



EN 15651-1:2017 (E) 6 The primer shall be stated for the substrate concerned, if relevant (name, chemical type, etc.). 4.1.2 Thermogravimetric test The test shall be carried out in accordance with EN ISO 11358 on the uncured or wet sealant, between 35 °C and 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 shall be no significant difference between the reference curve and derivative (profile). In the case of a multi-component sealant, each component shall be evaluated (if relevant). 4.1.3 Density 4.1.3.1 Principal A pyknometer is filled with the product under test. The density is calculated from the mass of the product in the pyknometer and the known volume of the pyknometer. 4.1.3.2 Method A test temperature of (23,0 ± 0,5) °C shall be used and the test sample and pyknometer shall be conditioned to this temperature, and it shall be ensured that the temperature variation does not exceed 0,5 °C during testing. The determination of the density shall be in accordance with EN ISO 2811-1:2016 and should be carried out using a suitable 50 cm3 calibrated pyknometer as described in EN ISO 2811-1:2016, 6.1.1. An alternative is the 50 cm3 Hubbard pyknometer as described in ISO 3507. Measurements should be carried out on the uncured or wet sealant and in the case of a multi-component sealant, each component shall be evaluated. At least three samples shall be tested. The specific pyknometer used and the mean value, recorded to two decimal places, shall be declared. The tolerance of the declared values shall be within ± 5 %. 4.1.4 Indentation hardness (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. thickness, cure/drying times and temperature and relative humidity, specific Shore type (A, D…), test time, temperature, etc.). At least three samples shall be tested and five measurements taken per sample. The mean value and tolerances of all measurements, recorded to the nearest unit, shall be declared. 4.2 Conditioning, test procedure and substrates When determining the classification of a facade sealant according to the requirements of this standard, the same conditioning procedure shall be used in all relevant test methods (Method A or Method B conditioning shall be used for all relevant tests). For each test method, three test specimens for each substrate shall be tested. The same batch of sealant (and primer, if used) shall be used in all tests. The same substrates (material and surface finish) shall be used in all tests. The specific test conditions shall be in accordance with Table 1. SIST EN 15651-1:2017

NF = No Failure according to EN ISO 11600. 4.3.2 Sealants for facade elements used in cold climates 4.3.2.1 General This test has been developed to demonstrate that elastic sealants for exterior use perform well at lower temperatures than those currently tested at in EN ISO 11600 (e.g. common winter temperatures in Northern Europe). The specific intention is to ensure that the sealant continues to perform at – 30 °C, which is a common winter temperature in cold climate areas. The test is not relevant for plastic sealants (as defined by classes 12,5P and 7,5P in Table 2). In addition to the requirements given in Table 2, elastic non-structural sealants for facade elements required to maintain performance in cold climates (- 30 °C) shall fulfil the requirements given in Table 3. The classification of the sealant given in Table 2 shall be determined prior to this optional additional test and the corresponding test amplitude shall be applied to this additional test. The designation CC (cold climate) shall be declared for any sealant meeting the requirements of Tables 2 and 3. For example, Type F Class 25LM CC. SIST EN 15651-1:2017
