ETAG 001 Part 3, Page 12Temperature range: 20 to 25°CDuration of test: 100 hours. Following the test, after unloading the screw, an unconfined tension test to failureshall be performed.Test Criteria:During the constant load portion of the test (100 hours), no anchor shall fail. If concrete failure occurs the test shallbe repeated.The failure load of residual load bearing capacity shall be compared to reference tension tests according toreference tests in C50/60. The reduction factor shall fulfil req. α ≥ 0.9.Ca(OH) 2 -sol.
