6 Test specimens 6.1 Dimensions of test specimens Length: The test specimen, length (1 000 ± 10) mm, shall be cut at right angles to its length to give two end guards, length each (250 ± 5) mm, and a test length of (500 ± 5) mm. Thickness: The thickness shall be 100 mm or the largest thickness below 100 mm available. Inside diameter: Two sizes shall be tested, one between 25 mm and 65 mm and the other between 85 mm and 220 mm. The dimensions shall be as specified in the relevant product standard or annex to this European Standard. NOTE 1 In the absence of a product standard or any other European Technical Specification, the dimensions may be agreed between parties. NOTE 2 Testing may be performed on multi-layer systems to simulate the conditions existing in the application. If the pipe insulation is cut from a homogeneous, isotropic flat product, then the maximum service temperature can be obtained from tests carried out on the flat product with similar properties in accordance with EN 14706. 6.2 Number of test specimens The number of test specimens shall be
