Table 5.5 is given for bonded anchors to be used in cracked and non-cracked concrete based on unconfinedtests. A1 - tests with intermediate anchor sizes may be omitted only if a continuous bond resistance is shownwith A1 tests as confined tests for all anchor sizes.Table 5.6 is given for bonded anchors to be used in cracked and non-cracked concrete based on confined testsand calculated with setup.Test series A3 and A4 may be omitted for anchors to be used in non-cracked concrete only.For all tests for determination of admissible service conditions for tension resistance, Reference tension tests(R) shall be carried out in the same slab or batch (see 5.1.1) with the medium anchor size (see note 1 in Tables5.1 and 5.2).The reference tests for cracked concrete shall be carried out in a crack width of 0,3 mm.Table 5.5Admissible service condition tests for bonded anchors to be used in cracked and non-crackedconcrete based on unconfined testPurpose of test Concrete Crackwidth w(mm)Minimum number of tests for anchor sizes i m i lA1 (1) Tension in noncrackedC20/25 0 5 - 5 - 5lowstrength concreteA1 conf 5 5 5 5 5A2 (1) Tension in noncrackedC50/60 0 5 - 5 - 5highstrength concreteA3 (1) Tension in cracked C20/25 0,3 mm 5 - 5 - 5low strengthconcreteA4 (1) Tension in cracked C50/60 0,3 mm 5 - 5 - 5high strengthconcreteA14 (1) Tension test in C20/25 0 5 - 5 - 5cornerA20 (1) Minimum spacing C20/25 0 5 - 5 - 5and edgedistancesNotes to Table 5.5(0) R-tests for batch factor not included in table(1) Anchor size: s = smallest; i = intermediate; m = medium; l = largestExample for threaded rods:A1 confined tests show continuous bond resistance for all sizes.The applicant demands approval for 3 sizes; test all sizes.The applicant demands approval for 5 sizes; test 3 sizes (see table).The applicant demands approval for 8 sizes; test 4 sizes.The applicant demands approval for 11 sizes; test 5 sizes.The sizes shall be equally distributed in the range of all sizes.ETAG 001-5- 18 -
