The CAPO-TEST permits performing pullout tests on existing structures without the need of pre-installed inserts as in the LOK-TEST. CAPO-TEST provides a pullout test system similar to the LOK-TEST system for accurate on-site estimates of compressive strength of the outer 25 mm layer. Procedures for performing post-installed pullout tests, such as CAPO-TEST, are included in ASTM C900 and EN 12504-3.
