6.3 Conditioning of test specimens
The test specimens shall be stored for at least 6 h at (23 ± 5) °C. In case of dispute they shall be stored at (23 ± 2) °C and (50 ± 5) % RH for the time specified in the relevant product standard or at least 24 h.
In tropical Countries, different conditioning and testing conditions can be relevant. In this case, the conditions shall be (27 ± 5) °C and (65 ± 5) % RH.
7 Procedure
7.1 Test conditions
The initial temperature of test specimen and the hot pipe shall be (23 ± 5) °C.
In tropical countries, different conditioning and testing conditions can be relevant. In this case, the conditions shall be (27 ± 5) °C and (65 ± 5) % RH.
7.2 Test procedure
Measure the length, the inside diameter and the thickness of the test specimen, Ia. D1. do. in accordance with ISO 12628 to the nearest 0,5 mm.
Install the test specimen (the two guards and the test length of the test specimen) on the hot pipe and ensure contact on the upper part of the hot pipe between the test specimen and the hot surface. Avoid any longitudinal gaps and any gaps between the end guards and the test length of the test specimen. The installation practice shall duplicate the practice, if required in the product standard.
NOTE In cases where gaps of more than two millimetres develop between the end guards and the test length during the test, action should be taken to close the gap without disturbing the measurement.
Place the two pieces of flexible metal foil over the two end guards, length (250 ± 5) mm, and exert a pressure of 500 Pa (see 5A).
Place the third flexible metal foil, length (500 ± 5) mm, over the test specimen test length and exert a pressure of 500 Pa (see 5.4).
NOTE For polyethylene foam and flexible elastomerlc foam products, see Annex B. Measure the thickness of the test specimen, d1, to the nearest 0,1 mm.
Heat the test specimen using a temperature rate of increase between 50°C/hand 300 °C/h, as specified in the relevant product standard or annex of this International Standard.ISO 18096-2013 pdf free download.
