For dated refer-ences, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. EN 12275:1998, Mountaineering equipment — Connectors — Safety requirements and test methods ISO 1920-3, Testing of concrete - Part 3: Making and curing test specimens 3 Terms and definitions For the purposes of this European Standard, the following terms and definitions apply. 3.1 rock anchor anchoring device intended for repeated use after installation, that is inserted into a drilled hole in the rock and held in place by gluing, or expansion forces, or positive locking, and with an attachment point for a connector (in accordance with 3.1 of EN 12275:1998) 3.2 body of the rock anchor part of the rock anchor that will be installed in the rock 3.3 hanger attachment point capable of being separated from the body of a rock anchor 3.4 installed length distance from the rock surface to the furthest point of the body in mechanical contact with the rock or bonded to the rock, after installation 4 Safety requirements 4.1 Materials All parts of a rock anchor shall be manufactured from the same material. NOTE Depending on environmental factors, rock anchors are potentially liable to suffer from corrosion. Information on the choice of materials and the need for inspection and maintenance is given in Annex B. 4.2 Design 4.2.1 The overall thickness of the border of the eye shall be 3 mm. If the edges are bevelled, the remaining inner surface shall have a minimum width of 2 mm.

Key R minimum 10 mm NOTE A-A see Figure 2 Figure 1 — Clear width and external shape of the eye 4.2.3 All edges that can be handled after placement of the rock anchor in the rock shall be rounded to a radius R of minimum 0,2 mm or bevelled to a minimum of 0,2 mm × 45 ° (see Figure 2). This applies to inner and outer edges.
Key l1 minimum 0,2 mm × 45 ° l2 minimum 2 mm l3 minimum 3 mm Figure 2 — Internal edges of the eye 4.2.4 After inserting the rock anchor in the concrete block, the eye shall be wide enough to accommodate two pins, one with a diameter of (15 ± 0,1) mm for the lower part and one with a diameter of (11 ± 0,1) mm for the upper part (see Figure 1). 4.2.5 In case of expansion-type rock anchors the expansion shall not be dependent on contact with the bot-tom of the drilled hole.
