11、 2008 All rights reserved iiiForeword ISO (the International Organization for Standardization) 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 interest
12、ed in a subject for which a technical committee has been established has the right to 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 Co
13、mmission (IEC) on all matters of electrotechnical standardization. International Standards 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 techn
14、ical committees are circulated to the member bodies for voting. Publication as an International 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 s

ISO 22915-20 was prepared by Technical Committee ISO/TC 110, Industrial trucks, Subcommittee SC 2, Safety of powered industrial trucks.

The st
21、ability tests are presented in the form of a basic part describing and defining stability tests in general, together with separate parts that each give specific stability test criteria and requirements for a different truck type. From the very beginning, the task of the Working Group involved was to
22、 establish the new structure and revise existing standards to create a series of International Standards complying with the major legislative regulations in the world such as those in force in the EU, USA, Japan and Australia. For several problem areas compromises were needed and will be needed in t
23、he future. In order to ensure that these International Standards are actively used in the ISO member countries worldwide, it will be necessary that they replace existing national standards. Only in this way will there will be the guarantee that products in accordance with these International Standar
24、ds can be shipped worldwide, freely and without any technical barriers to trade.

25、e special condition of offset load, offset by utilization 1 Scope ISO 22915 deals with the safety of industrial trucks, as defined in ISO 5053, relative to their stability and the verification of that stability. For the purposes of ISO 22915, industrial trucks are wheeled, self-propelled or pedestri
26、an-propelled vehicles, excepting those running on rails. They are either operator-controlled or driverless and designed to carry, tow, push, lift, stack or tier in racks. This part of ISO 22915 specifies an additional test for verifying the stability of a laden truck whose utilization creates the sp
27、ecial operating condition whereby the load centre of gravity is substantially offset from the trucks longitudinal centre plane. It is applicable to the following types of truck: a) counterbalanced trucks, as specified in ISO 22915-2; b) reach (retractable mast or forks) and straddle trucks, as speci
28、fied in ISO 22915-3; c) pallet stackers, as specified in ISO 22915-4; d) bidirectional and multidirectional (retractable mast or forks) trucks, as specified in ISO 22195-7; e) rough-terrain variable reach trucks 1); f) counterbalanced trucks fitted with articulated steering 1); g) variable reach tru
29、cks 1); h) rough-terrain trucks with mast. A load is considered to be substantially offset if displaced by more than 100 mm, for a truck with a rated capacity 10 000 kg and 20 000 kg, 350 mm, for a truck with a rated capacity W 20 000 kg. 1) Intended to be covered by a future part of ISO 22915.

38、rd where the design permits. The load shall be raised to the maximum elevation. If the manufacturer shows other possible ratings on the capacity plate (see Clause 6), tests shall be carried out with maximum load at the corresponding height as well as with the load corresponding to the maximum height
39、 as agreed between the interested parties. 4.4 Tests for trucks with attachments Trucks with attachments shall be subjected to the foregoing stability tests, as appropriate. The test loads and their positioning shall be those specified on the capacity plate(s) of the truck equipped with the attachme
40、nt when used under the special operating condition and in accordance with the manufacturers instructions. The lift heights required in the tests shall be measured between the surface of the tilt table and the underside of the load in its approved handling position or the underside of the load handli
41、ng means, whichever is the smaller. 3) For other applicable truck types (see Scope), the position of the truck or the tilt table will be as given in the equivalent test of the respective part of ISO 22915.
