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.
Diese ÖNORM legt Prüfverfahren zur Bestimmung der Eigenschaften von dekorativen Hochdruck-Schichtpreßstoffplatten (HPL) fest. Diese Prüfverfahren sind vorzugsweise zur Prüfung der in ÖNORM EN 438-1 beschriebenen Platten bestimmt.
