Plastics piping systems - Glass-reinforced thermosetting plastics (GRP) pipes - Determination of initial longitudinal tensile properties

This standard specifies three test methods for determining the longitudinal tensile properties of pipes of glass-reinforced thermosetting plastics (GRP). The properties which can be determined are: - the longitudinal tensile strength; - the percentage ultimate elongation; - the longitudinal modulus of elasticity. Method A uses for the test piece(s) a longitudinal strip cut from a pipe. Method B uses a specified length of the full cross section of the pipe. Method C uses a notched plate cut from a pipe wall section.

Kunststoff-Rohrleitungssysteme - Rohre aus glasfaserverstärkten duroplastischen Kunststoffen (GFK) - Bestimmung der Anfangs-Zugeigenschaften in Längsrichtung

Diese Norm legt drei Prüfverfahren zur Bestimmung der Zugeigenschaften in Längseinrichtung von Rohren aus glasfaserverstärkten duroplastischen Kunststoffen fest, nämlich im einzelnen: - die Längßug-Festigkeit; - die prozentuale Bruchdehnung; - den Elastizitätsmodul in Längsrichtung. Bei Verfahren A wird als Probekörper ein Streifen verwendet, der in Längsrichtung aus einem Rohr entnommen wird. Bei Verfahren B wird eine festgelegete Länge des vollständigen Rohr-Querschnittes benutzt. Bei Verfahren C wird eine eingeschnürte Platte verwendet, die aus der Rohrwand entnommen wird.

Systemes de canalisations en plastiques - Tubes en plastiques thermodurcissables renforcés de verre (PRV) - Détermination des propriétés initiales en traction longitudinale

Cette norme spécifie trois méthodes d'essai pour la détermination des propriétés en traction longitudinale de tubes en plastique thermodurcissable renforcé de verre (PRV), en particulier. Les propriétés pouvant être déterminées sont: - la résistance à la traction longitudinale; - le pourcentage d'allongement ultime; - le module d'élasticité longitudinal. La méthode A utilise comme éprouvette une bande longitudinale découpée dans la paroi d'un tube. La méthode B utilise une section de tube complet et de longueur spécifiée. La méthode C utilise une plaque entaillée découpée dans la paroi d'un tube.

Overview

EN 1393:1996 is a CEN standard for plastics piping systems made from glass‑reinforced thermosetting plastics (GRP). It specifies three standardized test methods for the determination of the initial longitudinal tensile properties of GRP pipes. The standard defines how to measure the longitudinal tensile strength, percentage ultimate elongation, and longitudinal modulus of elasticity for pipe specimens.

Key Topics

• Scope
  • Applies to GRP (glass‑reinforced thermosetting plastics) pipes and sets out procedures to determine initial tensile behaviour in the pipe’s longitudinal direction.
• Measured properties
  • Longitudinal tensile strength
  • Percentage ultimate elongation
  • Longitudinal modulus of elasticity
• Test methods
  • Method A: Test pieces are longitudinal strips cut from the pipe wall.
  • Method B: Uses a specified length of the pipe’s full cross section as the test specimen.
  • Method C: Uses a notched plate cut from a pipe wall section to assess tensile response.
• Standardization context
  • Published by the European Committee for Standardization (CEN) as EN 1393:1996; intended for consistent, comparable test results across laboratories and manufacturers.

Applications

EN 1393:1996 is practical for:

• Manufacturers of GRP pipes for product development, production control and batch verification.
• Testing laboratories performing mechanical characterization and certification testing.
• Design engineers assessing material behaviour for structural or pressure-bearing applications.
• Quality assurance and compliance teams ensuring products meet specifications and regulatory requirements.
• Procurement and specification writers creating tender documents or technical specifications that require standardized tensile data.

Typical uses include material selection, comparative performance evaluation of GRP pipe constructions, validation of production processes, and R&D into laminate configurations and resin/fibre combinations.

Related standards

• EN 1393:1996 should be used alongside other CEN plastics piping system standards and GRP product standards that cover dimensional, structural and pressure testing. Consult current CEN listings for the latest related standards and any superseding revisions.
