BS 12572-2:2017 pdf download – Artificial climbing structures Part 2: Safety requirements and test methods for bouldering walls 4.4 Connection of modular foam safety mat elements If the impact absorbing materials consist of modular elements, the sections shall be securely connected together or the gaps shall be covered so that it is impossible for the climber to enter into the gaps between modular elements. If the impact absorbing materials are beneath a continuous surface cover, the cover shall be in sufficient tension to hold the foam safety mats closely together. Informative Annex G describes one possible method of testing modular foam safety mat element connections. 4.5 Structural integrity The structural integrity, including stability, of a bouldering wall shall be justified by calculation using the characteristic loads given in Table A.1 in accordance with Annexes A and B. Panels shall not overly deflect (see D.5). In all cases where a bouldering wall transmits loads to an existing structure (building, concrete platforms, ground) it shall be ensured that the structure can safely accommodate the loads imposed by the bouldering wall. 4.6 Impact resistance and deflection of surface elements When tested in accordance with Annex D there shall be no breaking or splitting of the surface element. The deflection of the panels shall be calculated by using the load 0,8 kN (see Annex A) or be tested in accordance with Annex D, D.5. When fixed according to the manufacturer’s specification, the maximum deflection of the surface element shall not exceed l/100, where l is the maximum length between the fixations of the surface 4.7 Panel insert resistance To evaluate the panel insert concerning the resistance to breakage while mounting the climbing holds onto the wall or during climbing use, the panel inserts shall be tested in accordance with Annex E. After test step c) any resulting deformation shall not exceed 0,5 mm at 1,2 kN. After procedure e) there shall be no pull out of the panel insert. Five samples (panel-insert combination) shall be tested. 4.8 Falling space Within the falling space there shall not be any exposed obstacles or edges which could lead to a hazard to the user. This does not apply to climbing structures and other obstacle-free surfaces or walls capable of withstanding accidental impacts. 4.9 Bouldering wall surfaces All reachable parts of the bouldering wall surface shall be free of sharp edges and burrs. Edges shall be rounded by...
