4.3.2 Sealants for glazing elements in cold climates 4.3.2.1 General This test has been developed to demonstrate that glazing sealants perform well at lower temperatures than those currently tested in EN ISO 11600 (i.e. common winter temperatures in Northern Europe). The specification intention is to ensure that the sealant continues to perform at - 30 °C, which is a common winter temperature in cold climate areas.
In addition to the requirements given in Table 2, non-structural sealants for glazing elements required to maintain performance in cold climate (- 30 °C) shall fulfil also requirements as 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 Table 2. For example, Type G Class 25LM CC. SIST EN 15651-2:2013

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.

4.3.3 Resistance to flow 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 x 10 mm. Testing shall be carried out under two 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. 4.3.4 Resistance to water and UV Evaluation according to EN ISO 11431 using only fully automated equipment. The specific conditions of the test following EN ISO 11431 will require fully automated equipment with immersion of the test specimen in demineralised water. The UV lamp will be switched off during the water immersion.
