24、non-structural facade sealants intended for sealing exterior wall joints, window and door perimeter joints in building construction, including the interior face. NOTE Provisions on assessment and verification of constancy of performance - AVCP (i.e. Product type determination and Factory Production
25、Control) and marking of these products are given in EN 156515. This European Standard does not apply to non-structural sealants in any of non-paste form, to those used in interior walls and/or partitions and to oil-based mastics. 2 Normative references The following documents, in whole or in part, a

35、and definitions given in EN ISO 6927 and the following apply. 3.1 non-reactive sealant mainly physical drying mechanism, without significant change in the molecular weight of the main polymer 3.2 reactive sealant mainly curing by chemical reaction, with significant increase of the molecular weight o
36、f the main polymer 3.3 cure irreversible transformation of a sealant from a liquid or paste-like state into a hardened or rubber-like solid state 3.4 uncured / wet state of a sealant prior to the above transformation 4 Requirements 4.1 Identification requirements and test methods 4.1.1 Short descrip
37、tion of the sealant The short description of the non-structural sealant for facade elements shall include brand name, type (general chemical family), opaque or translucent, waterborne or solvent based or solvent free, reactive or non-reactive, and one or multi-component (e.g. waterborne acrylic opaq
38、ue and one component, etc.). BS EN 15651-1:2017EN 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
39、 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, e
40、ach 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
41、 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 suitabl
42、e 50 cm3calibrated pyknometer as described in EN ISO 2811-1:2016, 6.1.1. An alternative is the 50 cm3Hubbard 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
43、 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 accordan
44、ce 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
45、 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 s
46、tandard, 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 i
47、n 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.
