Thermoplastics pipes - Longitudinal reversion - Test method and parameters (ISO 2505:2005)

ISO 2505:2005 specifies a method for determining the longitudinal reversion of thermoplastics pipes, to be carried out in either a liquid or in air. In case of dispute, heated liquid is used as the reference. ISO 2505:2005 is applicable to all thermoplastics pipes with smooth internal and external walls of constant cross-section. It is not applicable to non-smooth structured-wall thermoplastics pipes.

Rohre aus Thermoplasten - Längsschrumpf - Prüfverfahren und Kennwerte (ISO 2505:2005)

Diese Internationale Norm legt ein Verfahren zur Bestimmung des Längsschrumpfes von Rohren aus Thermoplasten fest, deren Durchführung im Flüssigkeitsbad oder in Luft erfolgt. Im Schiedsfall ist das Verfahren im Flüssigkeitsbad als Referenzverfahren anzuwenden.
Diese Internationale Norm gilt für alle Rohre aus Thermoplasten mit glatten Innen- und Außenwänden mit konstantem Querschnitt. Sie gilt nicht für raue Rohre aus Thermoplasten mit strukturierten Wänden.
Die für den Rohrwerkstoff geeigneten Parameter sowie Empfehlungen für die maximalen Werte des Schrumpfes als Funktion des Rohrwerkstoffes sind in Anhang A angegeben.
ANMERKUNG      Die Messung des Längsschrumpfes wird für Rohre mit einer Wanddicke  16 mm als nicht relevant angesehen.

Tubes en matieres thermoplastiques - Retrait longitudinal a chaud - Méthode d'essai et parametres (ISO 2505:2005)

L'ISO 2505:2005 spécifie une méthode de détermination du retrait longitudinal à chaud des tubes en matières thermoplastiques, à réaliser soit dans un liquide, soit dans l'air. En cas de litige, la détermination à l'aide du liquide chauffé est la référence.
L'ISO 2505:2005 est applicable à tous les tubes en matières thermoplastiques à parois extérieure et intérieure lisses de section constante. Elle n'est pas applicable aux tubes en matières thermoplastiques à paroi structurée non lisse.
