Non destructive testing of welded joints of thermoplastics semifinished products - Part 4: High voltage testing
This European Standard specifies the equipment and methods for the high voltage testing of butt or overlap welded joints in thermoplastic sheets for locating through-thickness defects only. It applies to new unused constructions only.
Zerstörungsfreie Prüfung von Schweiβverbindungen thermoplastischer Kunstoffe - Teil 4: Hochspannungsprüfung
Diese Europäische Norm legt die lediglich zur Lokalisierung von Fehlstellen in Dickenrichtung anzuwendenden Prüfgeräte und -verfahren für die Hochspannungsprüfung von Stumpf- oder Überlapp(schweiß)nähten in thermoplastischen Kunststoffplatten fest. Die Norm gilt nur für neue, unge-brauchte Konstruktionen.
Essais non destructifs des assemblages soudés sur produits semi-finis en thermoplastiques - Partie 4 : Essais à haute tension
La présente Norme européenne spécifie l'équipement et les méthodes d'essais à haute tension des
assemblages soudés bout à bout ou à recouvrement de plaques en thermoplastiques permettant de localiser
uniquement les défauts traversants. Elle s'applique uniquement aux constructions neuves non utilisées.
Neporušitveno preskušanje zvarjenih spojev plastomernih polizdelkov - 4. del: Visokonapetostno preskušanje
Ta evropski standard določa opremo in postopke za visokonapetostno preskušanje soležnih ali prekrivnih zvarjenih spojev pri plastomernih ploščah izključno za ugotavljanje napak v debelini. Velja le za nove, neuporabljene konstrukcije.

4 Principle of the test A high voltage is applied to one side of the joint to be tested using a suitable electrode, the other side of the material needs to be in contact with a conductive substrate which in some cases will need a connection back to the test equipment. The test shall be carried out with a voltage high enough to jump the gap between the test electrode and a conductor. A defect is indicated by a spark discharge and, depending on the equipment used, a simultaneous optical and / or acoustic signal.
The health and safety aspects (e.g. electric shocks, risks of explosions in flammable atmosphere) together with the environmental impacts (e.g. electromagnetic disturbances) shall be thoroughly considered before operating the equipment.
NOTE Moisture in concrete can make it sufficiently conductive to allow high voltage testing to be used. SIST EN 13100-4:2014
