ISO 18319-2:2022

This document specifies requirements for unidirectional carbon fibre-reinforced polymer (CFRP) strips as external-bonded reinforcements on the concrete substrate. This document is applicable for the CFRP strips that: — consist of carbon fibre and thermoset resin; — are manufactured by pultrusion method; — have a carbon fibre fraction over 60 % by volume; and — have a thickness within 3 mm. This document specifies the methodologies to express the mechanical properties as characteristic values, appearance and dimensions, and sampling test.
