5 Requirements
5.1 General
Product properties shall be tested in accordance with Clause 6. To comply with this document, products shall meet the requirements of 5.2 to 5.8, where applicable.
The test methods to be used for determination of each property are given in Table 5, which also shows the required test specimen dimensions and the minimum number of test specimens required to give one test result.
One test result for a product property is the average of the measured values on the number of test specimens given in Table 5.
For FPC, see Annex A.
5.2 Classification
Products shall be classified into one of six types according to the classification temperature per Table 1.
5.3 Permanent linear change Permanent linear change upon heating shall not be greater than 4,0 %. The test temperature shall be at the classification temperature as per Table 1.
5.4 Thermal conductivity The manufacturer shall make declaration for the thermal conductivity λ D . The table or curve of conductivity versus temperature (from 200 °C up to 1 100 °C, where applicable) shall be given according to ISO 13787. Thermal conductivity shall be based upon measurements carried out in accordance with ISO 8302 up to 800°C and shall be in accordance with ISO 8894-1 or ISO 10635 for temperatures above 800 °C.
5.5 Dimensions The length, l, and width, b, shall be determined in accordance with ISO 29465. The thickness, d, shall be determined in accordance with ISO 10635. No test result shall deviate from the nominal values by more than the tolerances given in Table 2.
