This part of ISO 4586 specifies methods of test for determination of the properties of high-pressure decorative laminated sheets as defined in Clause 3. These methods are primarily intended for testing the sheets specified in ISO 4586-1. The precision of the test methods specified in Clauses 4, 7 and 11 of this part of ISO 4586 is not known because inter-laboratory data are not available. When inter-laboratory data are obtained, precision statements will be added to the test methods at the following revision. As all the other test methods have an end point determination based on subjective judgement, it is not meaningful to make a statement of precision in these cases.
