Note 2 to entry: 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. The procedure may be an iterative process.

The length and width or diameter shall be as specified in the relevant product standard or in annexes to this European Standard. b) Thickness: The test specimen thickness shall be (100 ± 5) mm prepared by slicing if needed. In the absence of a product standard or any other European Technical Specification the dimensions may be agreed between parties. Testing may be performed on multilayer systems to simulate the conditions existing in the application. 6.
