21、r permanent installation for use by children. This European Standard is not applicable to artificial climbing structures, which are used for training for sports activities, e.g. alpinism. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document
22、 and are indispensable for its application. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

23、t methods 3 Terms and definitions For the purposes of this document, the terms and definitions given in EN 1176-1:2008 and the following apply. 3.1 spatial network climbing equipment as geometric 3-dimensional assembly of flexible elements, which by its design will yield Note 1 to entry: Flexible el
24、ements can be e.g. ropes, chains, etc. Note 2 to entry: See Figure 1 for examples. Note 3 to entry: Because of the way in which climbing equipment is used (see EN 11761:2008, 3.2) if the user were to fall, this would be a vertical downward fall into the structure. Therefore, structural elements outs
25、ide the net are not considered to be in the falling space.

27、ht of 1 800 mm, to be introduced into the cellular structure and to pass through, see Figures 2 and 3. If the cylindrical body passes through, the falling height and the shock absorbing surface shall conform to EN 1176-1. NOTE The dimensions of the imaginary cylinder are derived from anthropometric
28、data and have been selected to ensure that a secure hold can be achieved by the user from any point within the net structure.

29、dditional requirements for mesh size in 3-dimensional arranged planar nets If a 3-dimensional assembly is an arrangement of planar nets (see Figure 1 c) with a vertical separation greater than 1 000 mm, the diameter of the largest circle that can be inscribed in all net openings shall be not greater
30、 than 420 mm when unloaded, see Figure 4. Where the arrangement of planar nets has a lower net with mesh size greater than 420 mm circular inner diameter, the impact attenuating surface below the lower of the nets shall have a critical fall height appropriate for the highest planar net with a mesh s
31、ize greater than 420 mm circular inner diameter. NOTE The mesh size of planar nets has been reduced to 420 mm to compensate for the reduction in grip opportunities within a 2-dimensional net structure.

32、f effective diameter of mesh size 4.3 Protection against injuries in the falling space The free height of fall (h) shall be as given in EN 1176-1:2008, 3.6, and shall be measured as shown in Figure 5.

34、1:2014EN 1176-11:2014 (E) 8 NOTE 2 Persons climbing on the outside of inclined 3-dimensional climbing structures (e. g. pyramids) do not fall to the outside, due to their orientation while climbing, but fall vertically downwards into the structure. When non-flexible elements (e.g. support poles) are
35、 arranged in a slanted position and have a smooth surface, they have a deflecting character and the impact energy is reduced. The maximum internal height of fall can then be increased in accordance with Table 1. Table 1 Maximum internal height of fall Deviation from horizontal Factor Height of fall

Appropriate IAS (Impact Absorbing Surface) materials are required on any surrounding impact area. Rope structures which
37、 are designed to yield in use are not regarded as hard objects in the falling space. 4.4 Converging parts Converging parts within spatial networks shall be exempt from the requirements of EN 1176-1:2008, 4.2.7.2 b). Where two linear elements converge at least one shall be flexible. Above 600 mm from
38、 the ground the angle formed between converging parts with a lower edge above the horizontal shall be more than 55. The angle formed by two converging parts shall be measured by a measuring device, such as a protractor. If the measurement device cannot be freely inserted in the opening use the test
39、template according to Figure D.2 of EN 1176-1:2008 applying a force of (222 5) N and re-measure the angle using the measuring device (see Figure 6).

40、 angle of platonic solids is 60. To allow for the flexibility of the ropes an angle of 55 is acceptable. 5 Test reports Test reports shall be in accordance with EN 1176-1:2008, Clause 5, in addition to the following: a) test report regarding compliance with EN 1176-11; b) certification of conformity
