If according to the chosen design method thecharacteristic resistance for concrete failure is needed, it may be necessary to use screws or bolts of higherstrength than those specified, in order to achieve a concrete failure in tests; if higher strength screws or bolts areused, the functioning of the anchors shall not be influenced in any way.Sometimes the tests are carried out with samples specially produced for the tests before issuing the ETA. If so,it shall be verified that the anchors subsequently produced conform in all respects, particularly suitability andbearing behaviour, with the anchors tested. 2 TEST MEMBERS The test members shall be made in accordance with ENV 206 [8] and comply with the following: 2.1Aggregates Aggregates shall be of medium hardness and with a grading curve falling within the boundaries given in Figure2.1. The maximum aggregate size should be 16 mm or 20 mm. The aggregate density shall be between 2.0 and3.0 t/m 3 (see ENV 206 [8] and ISO 6783 [9]). Figure 2.1 Admissible region for the grading curve 2.2Cement The concrete shall be produced using Portland cement type CEM I 32.5 or CEM I 42.5 (see ENV 197-1 [10]). 2.3Water/cement ratio and cement content The water/cement ratio should not exceed 0.75 and the cement content should be at least 240 kg/m 3 .No additives likely to change the concrete properties (e.g. fly ash, or silica fume, limestone powder or otherpowders) should be included in the mix.  - 4 - 2.4Concrete strength Tests are carried out in concrete of two strengths: low strength (strength class C 20/25) and high strength(strength class C 50/60).The following average compressive strengths at the time of testing anchors shall be obtained for the twoclasses:C 20/25:f cm =20-30 MPa (cylinder: diameter 150 mm, height 300 mm)=25-35 MPa (cube:150 x 150 x 150 mm)C 50/60:f cm =50-60 MPa (cylinder: diameter 150 mm, height 300 mm)=60-70 MPa (cube:150 x 150 x 150 mm)It is recommended to measure the concrete compressive strength either on cylinders diameter 150 mm, height300 mm, or cubes 150 mm.If this is not done in certain cases, the concrete compressive strength may be converted thus:C 20/25:f cyl = 1125. f cube 150 (2.1a)C 50/60:f cyl = 1120. f cube 150 (2.1b)Conversion factors for cubes of different sizes:f cube 100 = 1095.   . f cube 150 (2.1c)f cube 150 = 1095.   . f cube 200 (2.1d)For every concreting operation, specimens (cylinder, cube) should be prepared having the dimensionsconventionally employed in the member country; the specimens being made and treated in the same way as thetest members.Generally, the concrete control specimens shall be tested on the same day as the anchors to which they relate.If a test series takes a number of days, the specimens should be tested at a time giving the best representationof the concrete strength at the time of the anchor tests, e.g. in general at the beginning and at the end of thetests.The concrete strength at a certain age shall be measured on at least 3 specimens, the average value governs.If, when evaluating the test results, there should be doubts whether the strength of the control specimensrepresents the concrete strength of the test members, then at least three cores of 100 mm or 150 mm diametershould be taken from the test members outside the zones where the concrete has been damaged in the tests,and tested in compression. The cores shall be cut to a height equal to their diameter, and the surfaces to whichthe compression loads are applied shall be ground or capped. The compressive strength measured on thesecores may be converted into the strength of cubes by Equation (2.1e):f c,cube 200 = 0.95 f c,cube 150 = f c,core 100 = f c,core 150 (2.1e) 2.5Dimensions of test members The specification and dimensions of the test members should conform to the following:(a)Tests in cracked concreteThe tests are carried out on test members with unidirectional cracks, the crack width shall beapproximately constant throughout the member thickness. The thickness of the test member shall beh > 2 h ef but at least 100 mm. For bonded anchors see Part 5, for anchors for lightweight systems see
