8、 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 represen
9、ted 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 are dra
10、fted 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 International Sta
11、ndard 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 13459 was prepared by
12、 Technical Committee ISO/TC 127, Earth-moving machinery, Subcommittee SC 2, Safety, ergonomics and general requirements.This second edition cancels and replaces the first edition (ISO 13459:1997), which has been technically revised.

14、protective structures on earth-moving machinery as defined in ISO 6165.The effects of vibration are not considered a significant risk for short-term or temporary seats and are therefore outside the scope of this International Standard.2 Normative referencesThe following referenced documents are indi

40、otate (see Figure B.1) and translate as per the following.a) During lateral and longitudinal loading, it is permissible for the upper portion of the trainer DLV to be rotated sideways or forwards in the direction of ROPS deflection up to 15 around the locating axis (LA) line (see 3.1 and ISO 5353).
41、The portion below the LA line of the DLV may be disregarded. The rotation of the trainer DLV shall be limited to 15. If there is interference with any machine components or controls at a lesser angle, that angle shall be the limit of rotation. Upper-portion additional rotation due to deformation of
42、the mounting surface on which the trainer DLV is mounted is allowed.b) The trainer DLV may be also be translated 50 mm laterally or longitudinally in the direction of ROPS loading, to allow for soft tissue deflection of a large trainer.B.2 When the trainer DLV is rotated up to a maximum of 16 in the
43、 direction of ROPS deflection, the operator space shall allow the operator DLV to rotate by up to a maximum of 15 to avoid interference between the two DLVs.B.3 For rigid-frame dumpers that have the operator seat closer to the edge of the machine than the trainer seat, or that have side-mounted oper
44、ator stations and no appreciable lateral load on the trainer-seat side during a roll-over event, compliance with ISO 3471 meets the ROPS requirements for the trainer seat given in this International Standard (see 4.5).B.4 Measurement accuracy shall be in accordance with ISO 9248.15SIP15SIPa) Lateral
