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 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 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 SIST EN 15651-4:2013

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 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 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). 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.
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);  CC (= cold climate). 4.2.2.2 Classification according to the movement capability According to their movement capability, sealants are subdivided into different classes as given in Table 1. SIST EN 15651-4:2013

100 ± 25 25,0 20 100
± 20 20,0 12,5 60 ± 12,5 12,5 a For the correct interpretation and application of movement capability to the design of joints, relevant national standards and advisory documents should be considered.
4.2.2.3 Classification according to the secant tensile modulus Sealants of class 25 and class 20 are additionally sub-classified according to their secant tensile modulus (see EN ISO 6927 and EN ISO 11600):  low modulus: code LM;  high modulus: code HM. If the evaluated secant tensile modulus value exceeds the values specified below for either or both temperatures, the sealant shall be classified as high modulus. Specified values (see Tables 2 and 3, second column) are as follows:  0,4 N/mm2 at + 23 °C;  0,6 N/mm2 at - 20 °C.
The secant modulus shall be the mean value of the three measured values. Round the mean value to one decimal place. Substrates to be used in all mechanical tests concerned are; mortar M1 or M2 according to ISO 13640 and/or other substrates. 4.3 Performance requirements and test methods for non-structural sealants for pedestrian walkways 4.3.1 General The requirements and test methods are specified in Table 2.

4.3.2 Sealants in pedestrian walkways 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 ºC, which is a common winter temperature in cold climate areas.
The designation CC (cold climate) shall be declared for any sealant meeting the requirements of Table 2. For example, Type PW Class 25LM CC. Anodised aluminium and/or mortar M1 or M2 substrates, according to ISO 13640, shall be used. 4.3.2.2 Tensile properties - Secant modulus to EN ISO 8339 - test procedure at (- 30 ± 2) °C The test specimens shall be stored at (- 30 ±
2) °C for at least 4 h before the start of the test. The spacers for the preparation of the test specimens shall be removed and the test specimen placed in the tensile test machine and extended at (- 30 ±
2) °C at a rate of (5,5 ±
0,7) mm/min until rupture occurs. The force/extension diagram shall be recorded. 4.3.2.3 Tensile properties at maintained extension to EN ISO 8340 - test procedure at (- 30 ± 2) °C
The test specimens shall be stored at (− 30 ±
2) °C for at least 4 h before the start of the test. The spacers for the preparation of the test specimens shall be removed and the test specimens placed in the tensile test machine at (- 30 ±
2) °C and extended at a rate of (5,5 ±
0,7) mm/min by 60 % or 100 % of the original width (to 19,2 mm and 24 mm respectively). The separators shall be used to maintain the elongation at (- 30 ±
2) °C for 24 h. The test specimens shall be brought to (23 ±
2) °C. The depth of any loss of adhesion or cohesion shall be measured using a suitable measuring device capable of reading to 0,5 mm. 4.3.2.4

4.3.2.5 Resistance to flow for non-sagging sealants The resistance to flow shall be measured according to EN ISO 7390, with the precise test method modified according to the following details. A vertical, anodised aluminium U-profile shall be used with dimensions 20 mm × 10 mm. Testing shall be carried out under two test temperature conditions: a) temperature of (50 ± 2) °C and relative humidity of (50 ± 10) %; b) temperature of (5 ± 2) °C. If the flow exceeds the required value, then the test may be repeated once. SIST EN 15651-4:2013

Conditioning: Method B.
Test procedure at (23 ± 2) °C. After conditioning Method A or Method B, the test specimens shall be cut in the centre with a 6 mm broad knife blade or chisel blade through the complete thickness of the sealant (12 mm) (see Figure 1).
Afterwards the specimen has to be extended to the double of the movement capability e.g. a sealant with 25 % movement capability shall be extended to 50 % (from 12 mm to 18 mm). An example of an extended sealant with cut is shown in Figure 2.
After 24 h elongation, the test specimen will be examined and any tear propagation noted. The position of the cut can be taken from Figure 1. The sealant meets the requirement if the cut in the extended specimen does not exceed 12 mm in the length of the sealant.

4.4.2 Artificial weathering by UV-radiation Joint sealants have to be sufficiently resistant to weathering by outdoor use. This standard is achieved when the change of the tensile strength value is not bigger than 20 % according to the test mentioned below after the exposure with artificial weathering,. The tensile strength value at test elongation must be calculated and the change must be presented compared to untreated test specimen. The weathering test has to be performed according to EN ISO 11431. The positioning of the test specimen is shown in Figure 3. A contact material is used instead of glass concrete and also the direction of light exposure has to be changed to the surface of the sealant. SIST EN 15651-4:2013
