This standard BS ISO 4152:2021 Glass‐reinforced thermosetting plastics (GRP) pipes. Determination of the apparent axial long‐term modulus of pipes subject to beam bending is classified in these ICS categories:
- 23.040.20 Plastics pipes
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.
