High-pressure decorative laminates (HPL) - Sheets based on thermosetting resins (usually called laminates) - Part 2: Determination of properties

This European Standard 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, EN 438-4, EN 438-5, EN 438-6, EN 438-8, and EN 438-9.
The precision of the test methods, specified in this European Standard, is not known because inter-laboratory data are not yet available. When inter-laboratory data will be obtained, precision statements will be added to the test method at the following revision. For those test methods having an end point determination based on subjective judgement, it is not meaningful to make a statement of precision.

Dekorative Hochdruck-Schichtpressstoffplatten (HPL) - Platten auf Basis härtbarer Harze (Schichtpressstoffe) - Teil 2: Bestimmung der Eigenschaften

Diese Europäische Norm legt die Prüfverfahren für die Bestimmung der Eigenschaften der im Abschnitt 3 de¬finierten dekorativen Hochdruck-Schichtpressstoffplatten (HPL) fest. Diese Verfahren sind vorzugsweise zur Prüfung der Schichtpressstoffplatten bestimmt, die in EN 438 3, EN 438 4, EN 438 5, EN 438 6, EN 438 8 und EN 438 9 beschrieben werden.
Die Präzision des Prüfverfahrens, welches in dieser Europäischen Norm festgelegt ist, ist nicht bekannt, da noch keine Daten aus Ringversuchen zur Verfügung stehen. Sobald Daten aus Ringversuchen vorliegen, werden in der folgenden Überarbeitung Angaben zur Präzision des Prüfverfahrens ergänzt. Für alle übrigen Prüfverfahren, die eine Festlegung des Endpunktes umfassen, die auf einer subjektiven Einschätzung beruht, ist es nicht sinnvoll, in diesen Fällen eine Aussage zur Präzision zu machen.

Stratifiés décoratifs haute pression (HPL) - Plaques à base de résines thermodurcissables (communément appelées stratifiés) - Partie 2: Détermination des propriétés

La présente Norme européenne spécifie les méthodes d’essai pour la détermination des caractéristiques des plaques de stratifiés décoratifs haute pression définies à l’Article 3. Ces méthodes sont principalement destinées à la réalisation des essais sur les plaques spécifiées dans les EN 438-3, EN 438-4, EN 438-5, EN 438-6, EN 438-8 et EN 438-9.
La fidélité des méthodes d’essai, spécifiées dans la présente Norme européenne, n’est pas connue faute de données interlaboratoires. Lorsque des données interlaboratoires auront été obtenues, des états de fidélité seront ajoutés à la méthode d’essai dans une prochaine révision. Pour ces méthodes d’essai fondées sur une appréciation subjective du résultat final, il n’est pas significatif d’établir un état de fidélité dans ces cas.

Dekorativni visokotlačni laminati (HPL) - Plošče na osnovi duromernih smol - 2. del: Ugotavljanje lastnosti
