definitionsfor the purposes of this standard, the following definitions apply.3.1artificial climbing structure (acs)sports equipment consisting of a purpose-built climbing structure, which displays different construction characteristics, and is designed for different use objectives and not reserved for a particular age group3.2protection pointattachment point on the acs designed to protect the climber. this protection point can be used during progress on the acs. it can be fixed or movable3.3individual protection pointprotection point used to safeguard a climber in his/her progress on the acs3.4individual top rope systemprotection system which is fixed at the top of the climbing section and which is designed to take the rope for one climber3.5collective top rope systemprotection system which is fixed at the top of the climbing sections and which is designed to take the ropes of several climbers at once3.6individual ground protection pointanchoring point which is fixed to the ground at the base of the acs, and which is designed either to secure a belayer controlling the rope of a lead-climber or as a ground anchor for a self belaying system or as a fixing point for a protection system3.7collective ground protection systemprotection system which is fixed to the ground at the base of the acs, and which is designed to secure belayers controlling the ropes of lead-climbers, or as a ground anchor for self belaying systems3.8 stanceposition on the acs constituted by either a single point or two points linked together where the climber can stop, protect him/herself and his/her fellow climber who can join him/her before continuing the climb from the stance3.9 spanpart of a collective top rope system measured between two consecutive supports or attachments (seefigure

pointsthe maximum distance, x, for the placement of the individual protection point which follows the point situated at the height of h (see figure 2) shall be determined by using formula (1).x = (h + 2,0)5where(1)if there are protection points, the maximum of the first point shall not exceed 3,10 m.for removable protection points, the maximum distance shall be measured from centre to centre ofthe implantation points at 908 to the surface of the acs (see figures 2c and 2d).4.2 geometrical requirementsall protection points and stance points with the exception of those located at the top of the climbing sections shall be in accordance with figure 3.h is the distance between the point and the ground or an obstacle, whichever is the closest, measured vertically, in metres, beneath the point in all cases.for permanent protection points, the maximum distance shall be measured from the lowest internal point of the attachment point (see figure 2c).the bar or device over or through which the rope passes in either a collective or individual top rope system shall be rounded in accordance with figure 4.a) b)c) d) 1 reference point for measurementfigure 2 layout and placement of protection

components of the acs shall be justified by one of the following methods:a) by calculation using the calculation loads of table 1 in accordance with annex a and figures 5 and 6;b) if a) is not possible, by laboratory breaking tests in accordance with annex b.when tested in accordance with annex b, there shall be no breakage or tearing of the elements.figure 5 placement of the calculation

the proof testing only acts as a verification of good installation practice and cannot replace the calculations.4.4 impact test of surface elementswhen tested in accordance with annex c, there shall be no breaking or splitting of the surface element.4.5 proof testingwhen tested in accordance with annex d, there shall be no breaking, tearing or destruction of the elements after testing.5 markingall acs shall be marked in a clearly visible place with a notice comprising of:a) the name or trademark of the manufacturer;b) the name of importer or supplier;c) the name of the installer;d) the purpose of this equipment;e) the date of proof testing;f) the maximum number of climbers on the acs;g) if an acs is not calculated to allow the placement of protection points (individual, collective or stance) this shall be mentioned;h) the maximum number of climbing sections useable simultaneously.6 instruction manualan instruction manual shall be provided including the following information:a) all the information contained in clause 5 marking;b) the position and type of protection points on theacs.7 conformity of acsto be declared to conform, the acs and its components shall be calculated and tested in accordance with the proof tests fixed in this european standard.the proof tests shall be made at the first installation. the calculations shall be supplied to the client.for all further reconfigurations only the new calculations and visual verifications according to the standard and the manufacturers instructions are necessary.annex a (normative) calculationsa.1 calculation of componentsthe resistance of the components and the various elements which make up the internal protection chain in an acs shall be subject to overall and individual justification by calculation, or failing this, by breaking tests on samples (see annex b).the various elements shall be justified according to the calculation rules for each material making up the acs.a.2 calculation of stabilitya.2.1 demonstrate the stability of an acs by calculation and ensure that it is suitable to be fixed to the surrounding structure.a.2.2 calculate the overall stability of an acs using the stability loads given in table 1.a.2.3 for an external acs add the factors relating to climatic conditions, e.g. wind loads, snow loads etc.a.2.4 if an acs has a collective top rope system, the manufacturer shall specify the maximum number of climbers that can use the system simultaneously.a.2.5 in all cases, the manufacturer shall specify the maximum number of different climbing sections on the acs and the number of climbing sections useable simultaneously.a.2.6 for the calculation of the stability of an acswith protection points: calculate the point of maximum instability of theacs; apply the load of 10 kn at this point or 18 kn if it is a single anchor stance, or of 10 kn simultaneously on each point if it is a linked stance; add 3,8 kn for each successive top rope point at both sides of the point of maximum instability.on each occasion of such application the calculation shall show that the acs remains stable.a.2.7 for the calculation of the stability of an acswithout protection points calculate the point of maximum instability; apply a load of 1,2 kn at this point; add square metre by square metre in all possible directions around this point 0,6 kn/m2 until this load reaches the calculation load for the maximum number of climbers.on each occasion of such application, the calculation shall show that the acs remains stable.annex b (normative) laboratory testsb.1 generalwhen carrying out breaking tests on non-calculable elements of the structure, the force brought to bear on these elements shall be the same as would be applied when applying the minimum breaking loads in table 1 t
