22、uipment 3.3 static load load acting on the equipment due to its structure, added weights and prestressed components 3.4 dynamic factor factor to take account of the increase in effective body mass during a dynamic movement 3.5 safety factor factor intended to cover uncertainties in the body loading
23、and dynamic factor used, and which does not cover allowance for variations in materials and manufacturing processes BS EN 913:2008EN 913:2008 (E) 5 3.6 variable load loads due to factors other than the static and body loads 4 Hazard assessment The assessment of hazards has been based on EN ISO 12100
24、-1. Twelve categories of hazard or sources of hazard have been considered relevant to gymnastic equipment. These are as follows: a) crushing; b) shearing; c) cutting and severing; d) entanglement and trapping; e) impact; f) stabbing or puncture; g) friction and abrasion; h) insufficient mechanical s
25、trength; i) use of unsuitable material; j) unintended movement, including sliding; k) unsuitable ergonomic design; l) fire; m) wrong or missing information. 5 General safety requirements 5.1 Surface finish There shall be no protruding nails, projecting wire rope terminations or pointed or sharp-edge
26、d components. Rough surfaces should not present any risk of injury. All welds shall be smooth. Protruding bolt threads within any accessible part of the equipment shall be permanently covered, e.g. dome headed nuts. Nuts and bolt heads that project less than 8 mm are permitted in non accessible part
27、s, provided they are free from burrs. Corners, edges and projecting parts within the space occupied by the user that protrude more than 8 mm, and which are not shielded by adjacent areas that are not more than 25 mm from the end of the projecting part, shall be rounded off. The minimum radius of the
28、 curve shall be 3 mm. Figure 1 shows examples of protection for nuts and bolts and permissible protruding parts. Figure 2 shows examples of non-permissible protruding parts. NOTE This requirement is intended only to prevent injuries caused by unintended contact with components. BS EN 913:2008EN 913:

31、 of equipment are able to move relative to each other or to the floor, either by design or through deflection or bending under load, no entrapment point shall be created by such movement. These requirements shall be assessed by carrying out a visual inspection and measurement using the meth-ods spec
32、ified in Annex A. No danger of head and neck entrapment is considered to exist where the lowest part of the circumference of an opening is less than 600 mm above floor level. Where an item of equipment may be used at different heights or in different orientations, all possible heights and orientatio
33、ns must be considered. These requirements also apply to all parts used during adjustment and transportation of equipment. 5.2.2 Unintentional dropping Where a transport system is used, it shall not be possible for the equipment to drop when loaded at one end with a minimum weight of 750 N. When a tr
34、ansport system encounters a threshold the mechanism shall not be able to disengage or drop unin-tentionally. 5.3 Stability and strength 5.3.1 General Unless specified elsewhere in individual equipment standards, verification of the stability and strength of equipment shall be achieved by engineering
35、 calculation or by testing in accordance with the procedures speci-fied in Annex B. 5.3.2 Stability For stability testing where the normal action produces a destabilising force in a horizontal direction, e.g. vault-ing, the theoretical horizontal test force shall be calculated using the formula give
36、n in B.1.7. The calculation shall give a result which is 35 % of the self weight of the equipment or 50 N, whichever is the greater. Unless specified elsewhere in individual equipment standards, for equipment with unfixed body sections an actual test shall be carried out with a theoretical horizonta
37、l test force of 65 % of the theoretical test force calcu-lated according to the formula given in B.1.7, or 50 N, whichever is the greater. Unfixed body sections shall not become separated. 5.3.3 Strength When tested in accordance with Annex B, equipment shall not collapse or fracture, or show any pe
38、rmanent deformation that would result in an additional safety hazard as described in the standard. 5.4 Adjustment devices Any adjustment devices shall prevent accidental changes during use of the device or the equipment. BS EN 913:2008EN 913:2008 (E) 8 None of the operating levers shall protrude int
39、o the users free space. This shall be assessed by carrying out a visual inspection and operation of the adjustment device. 5.5 Shock absorption of top padding When tested in accordance with the method specified in Annex C, the peak acceleration shall not exceed 500 m/s, if not specified in other, in
40、dividual equipment standards. 6 Marking All gymnastic equipment shall bear the following marking: a) number of the relevant European Standard; b) name, trademark or other means of identification of the manufacturer, retailer or importer; c) year of manufacture; d) number of users for which the equip
41、ment is intended. BS EN 913:2008EN 913:2008 (E) 9 Annex A (normative) Determination of entrapment A.1 Principle Test probes of specified dimensions are offered to potential entrapment points and a note is made of whether or not they can be inserted. In situations of doubt when using the probes relat
42、ing to the tolerance an accurate measurement should be made to ensure the opening is in accordance with the nominal dimension. All tests shall be performed in the most onerous way. A.2 Apparatus Test probes of dimensions as described in Figures A.1 and A.2. A.3 Conditioning and test temperature Cond
43、ition the equipment and test probes for a minimum of 3 h at the test temperature of (23 2) C. A.4 Procedure A.4.1 Head and neck entrapment A.4.1.1 General The probe shall be applied with its longitudinal axis perpendicular to the plane of the opening. No rotation of the probe about any axis other th
44、an the longitudinal axis is permitted. Translations perpendicular to the longi-tudinal axis of the probe are allowed. The longitudinal axis of the probe is considered to coincide with the longest axis of the probes handle. A.4.1.2 Procedure A.4.1.2.1 General Try to insert the cone shaped probe (see
45、Figure A.1) into the opening. If the probe can enter the opening (opening 110 mm) it shall also pass the opening with its largest dimension (230 mm). A.4.1.2.2 Partially bound openings Try to insert the cone shaped probe (see Figure A.1) into the opening. The probe shall not become stuck. If the pro
46、be can enter the opening it shall touch the bottom of the opening (see Figures A.3 and A.4). BS EN 913:2008EN 913:2008 (E) 10 A.4.1.2.3 V-shaped openings Try to insert the cone shaped probe (see Figure A.1) into the opening along the direction of its median line. The probe shall not become stuck. If
47、 the probe can enter the opening it shall touch the bottom of the opening (see Figures A.3 and A.4). A.4.2 Finger entrapment Try to insert the 8 mm diameter finger rod (see Figure A.2) into each relevant opening and, if the rod does not pass through, rotate it as illustrated in Figure A.5. Record an
48、d report if the rod enters the opening and if it locks in any position when moved through the conical arc shown in Figure A.5. If the 8 mm diameter finger rod passes through the opening, apply the 25 mm diameter finger rod (see Figure A.2). Record and report if the 25 mm diameter finger rod passes t
49、hrough the opening and, if it does, whether ac-cess is then given to another finger entrapment site. No opening which presents a risk of finger entrapment is permissible. An opening is considered to present a risk of finger entrapment if it can accommodate the 8 mm probe but not the 25 mm probe or its profile is such that the 8 mm probe can become locked in position or 25 mm probe cannot be inserted a full 100 mm into the opening and the opening gives access to another entrapment site A.5 Expression of results Report all
