ASTM D7522
Standard Test Method for Pull-Off Strength for FRP Laminate Systems Bonded to Concrete Substrate.
This test method describes the apparatus and method for evaluating the tensile strength of wet-laid or pultruded (factory-manufactured) fiber-reinforced polymer (FRP) systems adhesively bonded to a flat concrete substrate. The test determines the greatest perpendicular force (in tension) that an FRP system can withstand before a plug of material comes off. Failure will occur along the weakest plane within the composite system of the test device, FRP laminate, adhesive and substrate
