标准范围

本文件规定了一种确定管道视轴向长期模量的方法，该方法受垂直支撑端部耦合器之间梁弯曲挠度的影响，允许管道相对于耦合器旋转。结合ISO 10928，本文件将试验结果表示为表观轴向长期模量，用于计算ISO/TS 10986中规定的GRP管道跨中梁挠度和端部旋转。参考标准中规定了试验条件和要求。出于实际原因，该试验方法不适用于直径大于DN 600的管道。

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.
