Test report No. 380516/13936/CPR dated 4 March 2021 Page 3 of 3 Method The test was performed in accordance with the requirements of clauses 5 “High-temperature test” and 6 “Humidity tests” (test with condensation) of standard UNI EN ISO 12543-4:2011. High-temperature test The glass was placed in the fan oven and heated to a temperature of (100 ± 2) °C. This temperature was maintained for a period of 16 h, then the glass is allowed to cool to room temperature in accordance with subclause 5.3.2 of standard UNI EN ISO 12543-4:2011. At the end of the test, the glass was inspected at a distance between 30 cm and 50 cm in front of a white diffuse background in order to check for possible faults occurring in the interlayer (bubbles, delamination, cloudiness), as requested by subclause 5.4 of standard UNI EN ISO 12543-4:2011. Humidity test with condensation The glass was kept vertically over water for two weeks in a hermetically-sealed container able to maintain a temper- ature of (50 ± 5) °C, as requested by subclause 6.3.1 of standard UNI EN ISO 12543-4:2011. At the end of the test, the glass was inspected at a distance between 30 cm and 50 cm in front of a white diffuse background in order to check for possible faults occurring in the interlayer (bubbles, delamination, cloudiness), as requested by subclause 6.4 of standard UNI EN ISO 12543-4:2011. Note 1: as a departure from the method specified by standard UNI EN 14449:2005, the test was carried out using the 2011 version of stand- ard UNI EN ISO 12543-4. Results High-temperature test At the end of the test, no faults in the item were noted. Humidity test with condensation At the end of the test, no faults in the item were noted.
