23、 Note 1 to entry: See Annex A for protection provided by chocks. 3.2 means of attachment part of a chock which allows the attachment of a connector Note 1 to entry: Applies to connectors in accordance with EN 12275. 3.3 holding force force necessary to cause the chock or its means of attachment to b

24、reak or to be pulled through the test apparatus Note 1 to entry: The force is determined in the strength test according to 5.4.2. BS EN 12270:2013EN 12270:2013 (E) 5 4 Requirements 4.1 Design 4.1.1 Chocks may be fitted with a means of attachment by the manufacturer. 4.1.2 If a chock is not fitted wi

25、th a means of attachment, the chock shall be designed such that a means of attachment consisting of tape (according to EN 565) or accessory cord (according to EN 564) or rope (according to EN 892 or EN 1891) can be affixed. 4.1.3 If there is a textile means of attachment, whose strength is dependent

26、 on the integrity of the stitching, then the stitching shall contrast with the background in colour or surface appearance. 4.1.4 Any means of attachment shall be large enough to accommodate a pin with a diameter of (15 0,1) mm. 4.1.5 All edges of the chock and/or the means of attachment that can com

27、e into contact with fingers or combinable components shall be free from burrs. 4.2 Strength When tested according to 5.4.2, the holding force shall be at least the one(s) marked on the chock (see Clause 6 b) and be not less than 2,0 kN. 5 Test methods 5.1 Test samples For the test, as many test samp

28、les shall be provided as there are different chock orientations indicated by the manufacturer in the instructions for use. If a chock model is manufactured in different sizes, each size shall be tested. 5.2 Test apparatus for strength test 5.2.1 Layout The apparatus consists of two round steel suppo

29、rting jaws with a radius R = (65 2) mm for the chock and by means of a loading bar with a diameter of (10 0,1) mm for the means of attachment, see Figure 2 and Figure 6. An apparatus consisting of two round steel supporting jaws with a radius R = (25 1) mm shall be used for testing chocks where bmax

30、of the tested position S 12 kN If used correctly, sufficiently strong to withstand the highest conceivable forces generated in a fall. If used correctly, sufficiently strong to withstand the highest conceivable forces generated in a fall, provided a dynamic belay is in use and effective. 12 S 7 kN N

31、ot recommended for use on its own, since it will not withstand the highest conceivable force. It may be used as one component of a belay system where the force of a fall is shared between the components. If used correctly, sufficiently strong to withstand typical forces generated in a fall, provided

32、 a dynamic belay is in use and effective. It cannot be relied upon to withstand the highest forces that could be generated in a fall. S 7 kN Only to be used as part of a multicomponent belay system where the force of a fall will be shared between several components. Even if used correctly, and with

33、a dynamic belay in use, it cannot be relied upon to withstand typical forces generated in a fall. Wherever possible, it should be backed up with one or more devices of similar strength, in such a way as to share the load. General The behaviour of a chock in rock, when loaded dynamically, is not full

34、y predictable. At least two independent anchor points should always be used, each capable of providing protection as above.
