玻璃钢热固性塑料（GRP）管.受梁弯曲影响的管的表观轴向长期模量的测定

[中文适用范围]： 本文件规定了一种确定管道在垂直支撑的端部耦合器之间受到梁弯曲偏转的表观轴向长期模量的方法，该端部耦合器允许管道相对于耦合器旋转。 结合 ISO 10928，本文件将测试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 管道的中跨梁挠度和端部旋转。 测试条件和要求在参考标准中规定。 出于实际原因，该测试方法不适用于直径大于 DN 600 的情况。 [外文原描述]： 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.
