Описание (английский):

This document specifies a method for determining the apparent axial long-term modulus of pipes subject to beam bending deflection between vertically supported end-couplers, which allow rotation of the pipe relative to the couplers. In conjunction with ISO 10928, this document expresses the results of the test as an apparent axial long-term modulus for use in the calculation of mid-span beam deflection and end rotation of GRP pipes as specified in ISO/TS 10986. Test conditions and requirements are specified in the referring standard. For practical reasons, the test method is not suited for diameters greater than DN 600.

Abstract

Overview

ISO 4152:2021 - Glass‑reinforced thermosetting plastics (GRP) pipes - Determination of the apparent axial long‑term modulus of pipes subject to beam bending - specifies a laboratory method to determine the apparent axial long‑term modulus of GRP pipes under beam bending. The test measures time‑dependent deflection of a water‑filled pipe supported between end‑couplers that allow rotation, and expresses results for use in mid‑span deflection and end‑rotation calculations (as used in ISO/TS 10986). The method is intended for practical pipe diameters up to DN 600.

Key topics and technical requirements

Test principle: mount a pipe sample on end supports (end‑closures with rubber seals), fill with water, measure deflection at mid‑span and supports, and compute flexural deflection (centre minus average end deflection).
Apparatus: stiff supporting frame, circular end closures, bracket supports glued at pipe springlines, and continuous displacement measuring devices with data acquisition.
Measurement points and instrumentation:
- Six displacement transducers mounted at springline brackets (two at mid‑span, four near ends).
- Dimensional measuring devices for outside diameter, wall thickness and length (calibrated to ±1%).
- Zero readings taken within 1 hour of mounting; filling time
