This part of EN 438 specifies the methods of test for determination of the properties of high-pressure decorative laminates as defined in Clause 3. These methods are primarily intended for testing the sheets specified in EN 438-3, 4, 5 and 6.
The precision of the test methods specified in Clauses 5, 6, 7, 8, 9, 12, 17, 18, 32 and 33 of this part of EN 438 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.
