ISO 18319:2015规定了混凝土构件升级用纤维增强聚合物（FRP）板的要求。本国际标准规定了将机械性能表示为特征值、外观和尺寸以及抽样试验的方法。根据符合ISO 14484的适当设计规范中规定的特征值计算设计特性。本国际标准涵盖的FRP板的纤维方向是单向的。

ISO 18319:2015 specifies requirements for fibre-reinforced polymer (FRP) sheets for upgrading of concrete members. The methodologies to express the mechanical properties as characteristic values, appearance and dimensions, and sampling test are specified in this International Standard. The properties for design are calculated from the characteristic values, as prescribed in an appropriate design code which is in accordance with ISO 14484. The fibre orientation of the FRP sheets covered by this International Standard is unidirectional.
