This standard is one of a package of standards for mountaineering equipment, see annex A. This European Standard has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association, and supports essential requirements of EU Directive(s). For relationship with EU Directive(s), see informative Annex ZA, which is an integral part of this standard. Annexes A and ZA of this European Standard are for information only. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Czech Republic, Denmark, Finland, France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Netherlands, Norway, Portugal, Spain, Sweden, Switzerland and the United Kingdom.

These normative references are cited at the appropriate places in the text and the publications are listed hereafter. For dated references, subsequent amendments to or revisions of any of these publications apply to this European Standard only when incorporated in it by amendment or revision. For undated references, the latest edition of the publication referred to applies. prEN 12275, Mountaineering equipment Ð Connectors Ð Safety requirements and test methods. EN 20139, Textiles Ð Standard atmospheres for conditioning and testing (ISO 139:1973). 3 Definitions For the purposes of this standard, the following definitions apply. 3.1 frictional anchor adjustable wedge-shaped body, which is intended to be wedged in cracks in the rock and is able to withstand a load in the direction of the longitudinal axis of the means of attachment. 3.2 means of attachment any system which allows the attachment of a connector (in accordance with prEN 12275). 3.3 holding force force necessary to cause the frictional anchor to break or slip through the test apparatus, as determined in the strength test in accordance with 5.4.2. 4 Safety requirements 4.1 Design 4.1.1 Frictional anchors shall be fitted with a means of attachment to a connector. If the means of attachment is sewn, the stitching shall contrast with the background in colour or surface appearance. 4.1.2 The means of attachment shall be large enough to accomodate a pin with a diameter of 15 mm. 4.1.3 All edges of the frictional anchor and/or the means of attachment that may come into contact with fingers or combinable components shall be free from burrs. 4.2 Strength When tested in accordance with 5.4.2, the holding force shall be at least 5,0 kN. 5 Test methods 5.1 Test samples At least two frictional anchors shall be provided for the test. If a frictional anchor is manufactured in different sizes, each size shall be tested. 5.2 Apparatus for strength test 5.2.1 Layout The apparatus consists of two parallel, rigid steel supporting jaws for the adjustable parts of the frictional anchor and of a loading bar with a diameter of (10±0,1) mm for the means of attachment, see Figure 2. The static friction between the supporting jaws and the frictional anchor shall be great enough to prevent the frictional anchor from slipping through at the test load, but the maximal surface roughness of Rmaxshall not exceed 500 mm. The surface of the loading bar shall have an arithmetical mean deviation of the profile of Ra= 0,8 mm and a maximal surface roughness of Rmax= 6,3 mm. There are no surface roughness requirements for the loading bar when the means of attachment is other than textile material. 5.2.2 Adjustment The distance s between the supporting jaws shall be according to the following formula: Position 1: s = bmin+ (bmax2 bmin)/4 Position 2: s = bmin+ (bmax2 bmin)3/4 where bminis the minimum adjustable width bmaxis the maximum adjustable width, see Figure 1. If the range between bmaxand bminis less than 5 mm only one position according to the following formula shall be adjusted: s = bmin+ (bmax2 bmin)/2 Licensed Copy: sheffieldun sheffieldun, na, Sat Oct 28 16:50:52 GMT+00:00 2006, Uncontrolled Copy, (c) BSI Page 4 EN 12276:1998 BSI 02-1999 Figure 1 Ð Examples of frictional anchors Licensed Copy: sheffieldun sheffieldun, na, Sat Oct 28 16:50:52 GMT+00:00 2006, Uncontrolled Copy, (c) BSI Page 5 EN 12276:1998 BSI 02-1999 Dimension in millimetres 1) loading bar 2) supporting jaws 3) frictional anchor 4) means of attachment Figure 2 Ð Layout and adjustment of apparatus 5.3 Conditioning and test conditions For the strength test according to 5.4.2 condition frictional anchors with textile means of attachment in accordance with EN 20139; Carry out the strength test at a temperature of (23±5) 8C. For frictional anchors with textile means of attachment, start the strength test within 3 min of removing them from the conditioning atmosphere. 5.4 Procedure 5.4.1 Design 5.4.1.1 Check by visual examination that the requirements according to 4.1.1 are met. 5.4.1.2 Test the unloaded eye of the means of attachment in accordance with 4.1.2, with a pin of (15±0,1) mm diameter. 5.4.1.3 Check by visual examination and handling that the requirements according to 4.1.3 are met. 5.4.2 Strength 5.4.2.1 Rate of loading: Ð of 20 mm to 50 mm per minute if the frictional anchor does not contain textile elements Ð of 50 mm to 200 mm per minute if the frictional anchor contains a textile element, subjected to stress during the test. 5.4.2.2 Load at least one test sample in each of positions 1 and 2. 5.4.2.3 Apply a load to each frictional anchor until it breaks or until it is pulled out of the apparatus. 6 Information to be supplied a) the name or trademark of the manufacturer, importer or supplier; b) the number of this European Standard: EN 12276; c) the model (if more than one model is available); d) the size (if more than one size is available); e) the minimum holding force in kN, which the manufacturer ensures. The value shall be expressed as a whole number of kN. f) the meaning of any markings on the product; g) on the use of the product and the level of protection which it can provide; h) on how to choose other components for use in the system; i) on how to maintain and service the product; j) on the lifespan of the product or how to assess; k) on the effects of chemical reagents and temperature on the product; l) on the influence of wet and icy conditions; m) on the danger of sharp edges; n) on the influence of storage and ageing. 7 Marking Frictional anchors shall be marked clearly, indelibly and durably with at least the following information: a) name or trademark of the manufacturer, importer or supplier; b) the minimum holding force in kN. The marked force shall be a whole number of kN with the unit ªkNº.
