标准范围

ISO 10471:2003规定了在潮湿条件下，通过外推确定玻璃纤维增强热固性塑料（GRP）管道长期极限弯曲应变和长期极限相对环挠度的方法。给出了两种加载方法，一种使用板，另一种使用梁杆。这两种方法均可用于测量高达28%的相对垂直挠度。当预计将超过该水平时，该程序仅限于使用至少一根横梁。

ISO 10471:2003 specifies a method for determining by extrapolation the long-term ultimate bending strain and the calculation of the long-term ultimate relative ring deflection of glass-reinforced thermosetting plastics (GRP) pipes, under wet conditions.Two methods of loading are given, one using plates the other beam bars. Either method may be used for measurements of relative vertical deflection up to 28 %. When it is expected that this level is going to be exceeded then the procedure is limited to the use of at least one beam bar.
