13、dization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to
14、 be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Stan
15、dards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an Int
16、ernational Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights.

18、m Requirements and test methods ISO 14790:2005 (E)11 Scope This International Standard specifies the essential requirements (including certain quality aspects) of snowboard plate bindings without release mechanism. This International Standard is applicable to non-releasable snowboard plate bindings
19、for adults and children. This International Standard does not apply to snowboard plate bindings with a release mechanism or to snowboard soft bindings. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edi
20、tion cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

22、ance with ISO 11634) and a snowboard NOTE An antiskid pad is not a component part of a plate binding. 3.2 snowboard binding type C binding suitable exclusively for a body mass up to 45 kg (children) 3.3 snowboard binding type A binding suitable for over 45 kg body mass (adults) ISO 14790:2005 (E)24
23、Parameters All possible strains on the boot can be attributed to one torque, M, and one force, F, on each, x, y, z of a system of coordinates. The point of origin of the coordinates is fixed as in the centre of the ankle joint (defined by s1and s2in Figure 1). The torques and forces illustrated in t
24、he drawing in Figure 1 are positive. The corresponding parameters acting in opposite directions are given negative signs. The arrowheads indicate the sense of rotation of the snowboard-boot movement. Dimensions in millimetres s1100 s280 Figure 1 Torques and forces 5 Requirements 5.1 Function The sno
25、wboard binding shall be such that in practical use, the boot remains connected to the snowboard under all loads occurring in winter terrain. This requirement is met if, after all testing in accordance with 6.6, 6.7 and 6.8: a) there are no fractures, cracks or other indications of permanent deformat
26、ion in the binding; b) the binding can attach the boot in the normal manner; c) the attached boot does not slip out of the binding; d) the boot can be moved from the binding in the original manner. 5.2 Retaining leash for mounting point for retaining leash The mounting points for the retaining leash
27、 shall be indicated by the manufacturer. The minimum breaking force of the mounting point and of the retaining leash shall be at least 500 N. ISO 14790:2005 (E)35.3 Snow pack Each snowboard binding shall latch with a minimum of 2 mm snow pack between the boot sole and the binding. 5.4 Mounting screw
28、s The snowboard binding shall be supplied with all parts necessary for mounting. Metric screws shall be used, preferably M 6 class g, or ski binding screws in accordance with ISO 6004. 6 Test methods 6.1 Apparatus 6.1.1 Artificial leg, with fixed ankle joint of 80, medium size (see Figure 2). 6.1.2

30、needed. All tests shall be passed. 6.3 Loading rate Perform the test quasi-statically, ensuring that the following indicative values of the torque gradient are respected: a) torsion values: d50 N m/sdzMtu (1) b) forward bending value: d220 N m/sdyMtu (2c) lateral bending: d50 N m/sdxMtu (3) where M
31、is the torque in the x, y or z direction in newton metres; t is the time of load application in seconds. 6.4 Accuracy of measurement The measurement error of the value in torsion and in forward bending shall be no more than 2 %. The test equipment shall be designed to allow application of a torque (
32、see Table 1) with a force applied at the upper part of the 1 m shaft connected to the artificial leg (see Figure 2). Table 1 Direction and torque Direction Type A Type C Mz150 Nm 100 Nm My550 Nm 300 Nm Mx300 Nm 150 Nm 6.5 Fatigue test Test one snowboard binding with 50 000 sinusoidal load cycles at
33、a frequency of 1 Hz (maximum) in the Mydirection, see Figure 3. The test torque is 100 Nm for adults and (66 3,3 Nm) for children. Mount the binding on a steel plate of at least 10 mm thickness.

40、nstructions shall be given to the customer; f) indication that a retaining leash or a braking device shall be applied for the safe use of snowboards and that an appropriate antiskid pad has to be fitted for safe riding on T-bar lifts. 9 Instructions for use Each snowboard binding shall be supplied w
41、ith instructions for use, if possible with illustrations, which shall comprise the following items: a) indication of the scope of application (children/adults); b) indication how to step in and out of the binding and how the snowboard binding can be opened in straits after a fall; c) indication that
42、 the snowboard binding functions only with a boot sole which is cleaned of snow, ice and dirt; d) indications for maintenance and care, in particular the regular inspection of all screw connections and adjustment to the boot; e) indication how and where to attach the retaining leash, that the leash shall be used at all times while riding or carrying the board, and how to use the antiskid pad; f) a note that the mounting instructions shall be given to the customer.
