ISO 18319:2015 PDF Download

ISO 18319:2015 is a standard that lays out the specifications for fibre-reinforced polymer (FRP) sheets used for strengthening and upgrading concrete structures. The standard defines the mechanical properties of the FRP sheets, such as tensile strength and modulus of elasticity, and provides guidelines for expressing these properties as characteristic values.

The standard also outlines the requirements for the appearance and dimensions of the FRP sheets, ensuring that they meet the necessary quality standards. It specifies the sampling and testing methods to determine the mechanical properties of the FRP sheets accurately.

The characteristic values obtained from these tests are then used to calculate the design properties of the FRP sheets, which are used in conjunction with design codes specified in ISO 14484. The FRP sheets covered by this standard are unidirectional, meaning that the fibres within the sheets are aligned in a single direction.
