BS EN 12572-3:2017EN 12572-3:2017 (E) 4 Introduction The working group recognize that there is a potential danger to ACS users from being struck by falling pieces of climbing holds

20、that break whilst in use on an ACS. Some propriety systems within climbing holds have been developed by manufacturers in response to this problem but the systems have not been perfected and further development work is required. The aim is to develop a system that would prevent large pieces of a brok

21、en hold that could cause serious injury to ACS users, from being able to break-off and fall from the ACS. Designers and manufacturers are requested to work on new systems that would address this problem. BS EN 12572-3:2017EN 12572-3:2017 (E) 5 1 Scope This European Standard specifies the safety requ

22、irements and test methods for climbing holds. This European Standard is applicable to climbing holds, which are used for the natural progression of the climber, i.e. without the use of artificial means (e.g. ice axes, crampons, hooks, nuts) on artificial climbing structures (ACS) and bouldering wall

23、s. Climbing holds are designed to be mounted on the ACS with bolts, screws, etc. Climbing holds include large volumes or features that are designed for use without additional climbing holds being attached to them. The main fixation points for climbing holds forms part of the existing layout of the A

24、CS and are considered in EN 12572-1 and EN 12572-2. This European Standard is not applicable to ice climbing, dry tooling and playground equipment. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its applicati

Only holds greater than 100 g shall be tes

33、ted. 5.2 Material Dangerous substances shall not be used in the manufacture of climbing holds in such a way that they can cause adverse health effects to the user of the equipment. NOTE Attention is drawn to the provisions of the Dangerous Substances Directive 1907/2006 and its successive modificati

34、ons. Prohibited materials include but are not limited to, asbestos, lead, formaldehyde, coal tar oils, carbolineums and polychlorinated biphenyls (PCBs). 5.3 Ergonomic requirements a) The climbing surface of a hold shall be free from accessible sharp edges with a radius less than 0,5 mm and burrs; b

35、) There shall be no pointed climbing holds with a diameter less than 15 mm, which protrude more than 40 mm from the wall; c) There shall be no gaps between 8 mm and 25 mm and with a depth greater than 15 mm which can lead to entrapment, unless specifically designed for climbing. 5.4 Resistance to fi

36、xation force Climbing holds shall be tested in accordance with 6.2 and they shall not fracture. 5.5 Resistance to breakage in use Climbing holds shall be tested in accordance with 6.3 and they shall not fracture. 5.6 Dimension ratio This requirement is to protect the surface of the ACS and the panel

37、 insert. The hold shall be designed in such a way that: d2 3d1and d3 3d1according to Figure 2. BS EN 12572-3:2017EN 12572-3:2017 (E) 8 Key A is the holding point where the climber can exert the greatest force B opposite edge to point A d1is the distance between the fixation hole axis and the opposit

38、e edge B to point A d2is the parallel to the surface distance between point A and opposite edge B d3is the perpendicular to the surface distance between point A and opposite edge B Figure 2 Dimension Ratios of the hold 5.7 Volumes Volumes shall be fixed to the ACS ensuring the maximum load transfers

39、 efficiently to the ACS in accordance with the manufacturers instructions. The volume surface, body and panel inserts shall fulfil the requirements for climbing surfaces according EN 12572-1 and EN 12572-2. Volumes shall not have protection points. Volumes shall be fixed using multiple fixation poin

BS EN 12572-3:2017EN 12572-3:2017 (E) 9 6 Test methods 6.1 Sample preparation Hold samples shall be subjected to five temperature cycles each for a period of 1 h at 30 C followed by a period of 1 h at +70 C. Before performing the test cycles the climbing holds shall be wetted by submerging in ta

41、p water for 10 min. There shall be no visible signs of damage to the climbing holds after conditioning. Undamaged climbing holds shall then be tested according to 6.2 and 6.3. 6.2 Resistance to fixation force Testing shall be carried out with the climbing hold in a three-point bend scenario (see Fig

42、ure 3) as follows: a) Find the maximum width of a hold passing through the fixing hole. b) Define two perpendicular lines on the base at a distance D (see Figure 3 and Table 2) from the edge of the hold. c) Put iron rod bearings with a minimum radius of 10 mm under the hold on a flat and solid (e.g.

43、 steel plate) surface were the lines are located. d) The hold shall be loaded with the force F (see Table 2) in the bolt hole using a tool with the same form as the manufacturers recommended fixing (e.g. cap-head or countersunk) for 1 min at ambient temperature with relative humidity (50 5) %.

45、to be tested shall be selected as follows: a) divide each set of holds into size according to Table 1; b) chose for each size the hold with the biggest major axis to bolt-hole depth ratio; c) at least 5 % of the total number of different holds available from the manufacturer. 6.3 Structural integrit

46、y 6.3.1 Holds Fix the hold to a rigid surface with a torque on the fixation screw using the manufacturers recommended maximum tightening torque. Load the hold with a device which pushes or pulls in the most unfavourable usable position and direction against breakage in use with a force of 2,4 kN for

47、 1 min (see Figure 3). An example test setup is given in Annex A. Holds to be tested shall be selected as follows: a) divide each set of holds into size according to Table 1; b) chose for each size the hold with the largest dimension ratio. NOTE The value of 2,4 kN results from the maximum pushing f

48、orce from the foot of a climber: 0,8 kN resulting from the weight of the climber, 2 resulting from the dynamic movement, 1,5 (safety factor). 6.3.2 Structural integrity of volumes Fix the volume to a panel with all recommended fixation screws. Fix an exe bolt at the most unfavourable volume insert a

49、n pull with a force of 2,4 kN for 1 min in the most unfavourable direction(s).
