9、) 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 be repr
10、esented 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 Standards ar
11、e 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 Internation
12、al 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. ISO 24135 was pre
13、pared by Technical Committee ISO/TC 110, Industrial trucks, Subcommittee SC 2, Safety of powered industrial trucks.

23、2006(E) 2 ISO 2006 All rights reserved 4 Requirements 4.1 Seat belt assembly The seat belt assembly components shall be in accordance with either SAE J386, or E/ECE/324 Regulation 16, Revision 5:2005, Clause 6, but excluding 6.4. 4.2 Belt material The belt material shall be resistant to mild acids,
24、alkalis, mildew, ageing, moisture and sunlight and equal to or better than untreated polyester yarn. 4.3 Belt construction The strap shall not be less than 46 mm wide, measured with no load applied. 4.4 Performance On completion of the tests, according to Clause 5: a) there shall be no failure allow
25、ing release of the seat belt or structural failure of any part of the mounting structure, however, permanent deformation of the mounting structure is acceptable; b) there shall be no tearing, ripping or other damage to the belt; c) it shall be possible to release the operator restraint system, i.e.
26、by unfastening the buckle. Where a retractable seat belt mechanism is fitted, the locking function of the retractor device shall not depend solely on the speed or acceleration of the belt from the retractor, but shall activate at the lateral tilt angle of the truck designed by the manufacturer. This
27、 angle shall be no greater than 30. During the tests specified in Clause 5, there shall be no unintentional release of the fastener or retractor locking device (if fitted). 5 Test methods 5.1 General These are type tests and shall be carried out on an operator restraint system and its mounting struc
28、ture fitted to a truck of the type for which they have been designed. The lap-type seat belt assembly test shall test the belt and anchorages needed to connect it to the structure of the truck. On a suspension-type seat or a seat with integral seatbelt assembly, this shall include the anchorage for
29、the seat. 5.2 Seat belt test body blocks The test force for the lateral pull test specified in 5.3 shall be applied to the seat belt assembly and its mounting structure through a test body block, as shown in Figure 1. The test forces for the forward pull and retractor locking device tests specified
30、in 5.4 and 5.5 respectively shall be applied to the seat belt assembly and its mounting structure through a test body block, as shown in Figure 2.
