4 Requirements 4.1 General Product properties shall be assessed in accordance with Clause 5. To be in conformance with this document, products shall meet the requirements of 4.2 and 4.3, as appropriate. The test methods 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. 4.2 For all applications 4.2.1 Linear dimensions Length and width shall be measured in accordance with ISO 29465 for each of the four specimens. A minimum of four measurements shall be made for each dimension. Each value shall be within the tolerances specified in Table 1. The thickness of aerogel insulation shall be measured in accordance with ISO 29466 by using a square plate under pressure of not less than 250 Pa and shall be subject to the tolerances detailed in Table 1. The pressure employed during measurement shall be disclosed.
