ISO 10406-3:2019 (R2025)

This document specifies test methods applicable to 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 higher carbon fibre fraction such as over 60 %; and — have a thickness within 3 mm. Also, the test pieces for determining tensile properties are cut down from CFRP strips along the CFRP strips axis, and have bonded anchorage block at the both ends.
