Overview
EN 1394:1996 - "Plastics piping systems - Glass-reinforced thermosetting plastics (GRP) pipes - Determination of the apparent initial circumferential tensile strength" (adopted as SIST EN 1394:1997) is a CEN standard that defines test methods for measuring the apparent initial circumferential tensile strength of GRP (glass‑reinforced thermosetting plastics) pipes. The standard specifies six test methods to determine tensile strength per unit length in the circumferential direction. The burst test (method A) is applicable to all pipe types and sizes and is the preferred method for pipes up to and including DN 600.
Key Topics
- Scope of measurement: Determination of the apparent initial tensile strength in the circumferential direction, reported per unit length of GRP pipe.
- Test methods: Six standardized methods are provided; the burst test (method A) is highlighted as suitable for all types and preferred for pipes ≤ DN 600.
- Material focus: Applies specifically to glass‑reinforced thermosetting plastics (GRP) piping systems.
- Standard provenance: Published by CEN and adopted nationally (e.g., SIST EN 1394:1997); ICS classifications include 83.120 and 23.040.20, reflecting reinforced plastics and plastic pipes.
Applications
EN 1394 is practical for organizations involved in the design, manufacture, testing and specification of GRP piping systems:
- Manufacturers: To validate circumferential strength characteristics of GRP pipes during product development and quality control.
- Testing laboratories: To perform standardized tensile and burst testing for certification and compliance reporting.
- Engineers and specifiers: To select appropriate GRP pipe types and ensure structural adequacy for pressure and load conditions.
- Procurement and quality assurance: To define acceptance criteria and require consistent test evidence from suppliers.
Relevant use cases include water and wastewater mains, industrial process piping, and buried/above‑ground GRP installations where circumferential tensile strength is a critical performance parameter.
Benefits
- Provides repeatable, comparable test procedures for GRP pipe strength.
- Supports conformity assessment, product certification and specification writing.
- Helps ensure safety and long‑term reliability of GRP piping systems by quantifying initial tensile behavior.
Related Standards
- EN 1394 complements other CEN plastics piping standards for materials, design and testing of plastic and reinforced‑plastic pipes. Users should consult relevant CEN standards for overall system design, long‑term performance and jointing requirements.
