3 Terms and definitions
For the purposes of this European Standard, the following terms and definitions apply.
3.1
Maximum service temperature
will continue to function within specified limits of performance [prEN ISO 9229] NOTE 1 The required performance may be in the areas of dimensional stability, thermal properties, and mechanical properties as well as changes in appearance and resistance against creation of hazards such as internal self heating (see Annexes A and C and possible requirements in the relevant product standard).
NOTE 2 In the present test procedure, which is used as a reference, the test specimen is exposed to a temperature difference going from ambient to the maximum service temperature.
This may not reflect the actual application conditions when products are exposed to different temperatures on the two main faces, e.g. in multilayer systems or for faced products where the facing may limit the maximum service temperature.
4 Principle Measure thickness, length, and width after one sided heat treatment for a specified time period, at the maximum service temperature, achieved using a specified rate of temperature increase.
The thickness of the test specimen is measured during heat treatment, and the length and width only after cooling to ambient temperature. NOTE The procedure may be an iterative process.
