ISO 18319-2:2022 PDF Download

ISO 18319-2:2022 is a standard that provides specifications for carbon fibre-reinforced polymer (CFRP) strips, specifically designed for use as external-bonded reinforcements on concrete structures. These CFRP strips are constructed using carbon fibres and thermoset resin, and are manufactured via the pultrusion method. The standard applies to CFRP strips with a carbon fibre fraction exceeding 60% by volume and a thickness of up to 3mm.

The standard outlines the requirements for expressing the mechanical properties of the CFRP strips as characteristic values, including aspects such as strength and elasticity. It also covers criteria for evaluating the appearance and dimensions of the strips, ensuring they meet the necessary visual and dimensional standards. Additionally, the standard specifies the sampling methods and testing procedures to ensure the quality and performance of the CFRP strips.
