EN 959:2007 (E) 4 Introduction The text of this document is based on the former UIAA-Standard P (Union Internationale des Associations dAlpinisme), which has been prepared with international participation. This standard is one of a package of standards for mountaineering equip
17、ment, see Annex A. EN 959:2007 (E) 5 1 Scope This European Standard specifies safety requirements and test methods for rock anchors for use in mountaineering including climbing. 2 Normative references The following referenced documents are indispensable for the application of this document. For date
18、d refer-ences, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

19、 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 for
20、ces, 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
21、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,
22、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
23、shall have a minimum width of 2 mm. EN 959:2007 (E) 6 4.2.2 All corners that will be more than 12 mm from the rock surface shall be rounded to a radius R of a minimum 10 mm (see Figure 1). Dimensions in millimetres Key R minimum 10 mm NOTE A-A see Figure 2 Figure 1 Clear width and external shape of
24、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 l1minimum 0,2 mm 45 l2minimum 2 mm l3minimum 3 mm Figure 2 Inte
25、rnal 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 roc
26、k anchors the expansion shall not be dependent on contact with the bot-tom of the drilled hole. EN 959:2007 (E) 7 4.2.6 For glued-in rock anchors, the installed length shall be 70 mm minimum. For mechanical rock anchors, the installed length shall be at least five times the diameter of the drilled h
27、ole (in accordance with the manufacturers instructions). NOTE For installation in rock softer rather than the concrete test block, a longer length can be necessary to achieve the required load bearing capacity. Further information is given in Annex C. 4.3 Loadbearing capacity 4.3.1 Axial loadbearing
28、 capacity When tested in accordance with 5.3.2.2, the rock anchor shall withstand an axial load of 15 kN, without being pulled out of the concrete block or breaking. Permanent deformation is permissible. 4.3.2 Radial loadbearing capacity When tested in accordance with 5.3.2.3, the rock anchor shall
29、withstand a radial load of 25 kN, without being pulled out of the concrete block or breaking. Permanent deformation is permissible. 5 Test methods 5.1 Check of materials The manufacturer shall confirm that the requirements of 4.1 are met. 5.2 Apparatus 5.2.1 Tensile testing machine 5.2.2 Concrete bl
30、ock with minimum dimensions of 200 mm 200 mm 200 mm and a compressive strength of (50 10) N/mm2. The maximum grain size of the aggregate shall not exceed 16 mm. The compressive strength of the concrete block shall be verified on three test samples produced as specified in ISO 1920-3. NOTE All concre
31、te testing centres produce these types of concrete blocks to order. 5.3 Procedure 5.3.1 Examination of design Ensure by visual examination and check the dimensions that the specifications in accordance with 4.2.1 to 4.2.6 are met. EN 959:2007 (E) 8 5.3.2 Determination of load bearing capacity 5.3.2.
32、1 Install the rock anchor into a concrete block in accordance with the information supplied by the manufacturer. If rock anchor bodies are supplied without hangers, attach a hanger in accordance with the in-formation supplied by the manufacturer. If hangers are supplied without bodies, attach the ha
33、nger to a fixed structure in accordance with the information supplied by the manufacturer. 5.3.2.2 Attach the concrete block to the tensile testing machine using clamps at a distance a installed length l + 5 % away from the axis of the rock anchor (see Figure 3). Apply an axial load to the rock anch
34、or using a pin with a diameter of (10 0,1) mm in the eye at a rate of (35 15) mm/min, increasing the load to (8 0,25) kN then reducing the load to less than 0,5 kN. Apply this loading a total of ten times within 10 min. Again apply a load, increasing it until failure or until the rock anchor is pull
35、ed out of the concrete block.

Attach the con-crete block to the tens
36、ile testing machine using a support, and a clamp at a distance a installed length l + 5 % away from the axis of the rock anchor (see Figure 4). Apply a radial load to the rock anchor using a pin with a diameter of (10 0,1) mm in the eye at a rate of (35 15) mm/min, increasing the load to (8 0,25) kN
37、 then reducing the load to less than 0,5 kN. Apply this loading a total of ten times within 10 min. Again apply a load, increasing it until failure or until the rock anchor is pulled out of the concrete block. Key 1 Eye (clip) of the rock anchor 2 Clamp 3 Concrete block 4 Support over total width a

39、 manufacturer). EN 959:2007 (E) 10 7 Information supplied by the manufacturer The rock anchor shall be supplied with an explanatory leaflet, and written in at least the official language(s) of the state of destination within the European Community containing at least the following items: a) name and
40、 address of the manufacturer or their authorised representative; b) reference of this document: EN 959; c) model identifier (if more than one model is available); d) size (if more than one size is available); e) meaning of any marks on the product; f) components that comprise the complete rock ancho
41、r and the material used; g) use of the rock anchor; h) how to insert the rock anchor; i) how to choose other components for use in the system and the need for material compatibility (see Annex B); j) expected lifespan of the product when installed in different environments, particularly near sea wat
42、er or sea water spray (see Annex B); k) warning that the rock anchor can have a lower loadbearing capacity when installed in soft rock and what action to take to overcome the problem (see Annex C); l) how to assess the remaining lifespan of the product after installation, and when and how to remove
43、it from future use.
