26、nts used for movement joints in floors in building construction for interior and exterior use. Areas of application are: floor joints designed for pedestrian walkways, public areas, movement joints between concrete slabs, areas with pedestrian load, areas used with trolleys, walkable floors, balconi
27、es, terraces, warehouses. NOTE Provisions on assessment and verification of constancy of performance - AVCP (i.e. Product type determination and Factory Production Control) and marking of these products are given in EN 156515. Chemical containment, cold applied joint sealants for concrete pavements
28、to be used in roads, airfields and sewage treatment plants, perimeter seals and seals in wood floors are excluded. This European Standard does not apply to non-structural sealants in any of non-paste form, to those used in pedestrian walkways. 2 Normative references The following documents, in whole

39、 weight of the main polymer 3.2 cure irreversible transformation of a sealant from a liquid or paste-like state into a hardened or rubber-like solid state 3.3 uncured / wet state of a sealant prior to the above transformation 4 Requirements 4.1 Identification requirements 4.1.1 Short description of
40、the sealant The short description of the non-structural sealant for pedestrian walkways shall include brand name, type (general, chemical, family, one or multi-component e.g. one component Polyurethane sealant in different colours, etc.). The primer shall be stated for the substrate concerned, if re
41、levant (name, chemical type, etc.). BS EN 15651-4:2017EN 15651-4:2017 (E) 7 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
42、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 pyknomet
43、er 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
44、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 using a suitable 50 cm3calibrated pyknometer as described in EN ISO 2811-1:2016, 6.1.1. An alternative is the 50 cm3Hubbard pyknome
45、ter 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, sha
46、ll 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 sealant. The exact conditions of test shall be defined
47、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 n
48、earest unit, shall be declared. 4.2 Conditioning, test procedure and substrates 4.2.1 General When determining the classification of a sealant according to the requirements of this standard, the same conditioning procedure shall be used in all relevant test methods (use only Method A or Method B). F
49、or 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. 4.2.2 Classification 4.2.2.1 General Classes for cold applied elastic sealants for movement joints in floors in building construction are referred to as type: PW (= pedestrian walkways); EXT (= exterior application) and INT (= interior application); BS EN 15651-4:2017EN 15651-4:2017 (E) 8 CC (= cold c
