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.
