Foreword

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 interested 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 Commission (IEC) on all matters of electrotechnical standardization.

The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the different types of ISO documents should be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives ).

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. Details of any patent rights identified during the development of the document will be in the Introduction and/or on the ISO list of patent declarations received (see www.iso.org/patents ).

Any trade name used in this document is information given for the convenience of users and does not constitute an endorsement.

For an explanation of the voluntary nature of standards, the meaning of ISO specific terms and expressions related to conformity assessment, as well as information about ISO's adherence to the World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT), see www.iso.org/iso/foreword.html .

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

This second edition cancels and replaces the first edition (ISO 22915-20:2008), which has been technically revised.

The main changes are as follows:

• references to “This part of ISO 22915” have been replaced by “this document”;
• the applicable types of trucks listed in the scope have been updated;
• cross-references to figures and tests from other parts of the ISO 22915 series have been dated;
• normative references in Clause 2 have been updated;
• the Bibliography has been added;
• Figure 1 has been updated to include a “CG” key reference, a line to CG and an adjusted load height; a key has been added.

A list of all parts in the ISO 22915 series can be found on the ISO website.

1 Scope

This document specifies an additional test for verifying the stability of a laden truck whose utilization creates the special operating condition whereby the load centre of gravity is substantially offset from the truck's longitudinal centre plane or from the centred position by design.

A load is considered to be substantially offset if displaced by more than:

• 100 mm, for a truck with a rated capacity < 5 000 kg;
• 150 mm, for a truck with a rated capacity ≥ 5 000 kg and ≤ 10 000 kg;
• 250 mm, for a truck with a rated capacity > 10 000 kg and < 20 000 kg;
• 350 mm, for a truck with a rated capacity ≥ 20 000 kg.

This document is applicable to the following types of trucks as defined in ISO 5053-1:

• a) counterbalance trucks;
• b) reach and straddle trucks;
• c) pallet stackers;
• d) bidirectional and multidirectional trucks;
• e) industrial variable-reach trucks;
• f) rough-terrain trucks with mast;
• g) rough-terrain variable reach trucks;
• h) counterbalance trucks with articulated steering;
• i) variable-reach container handler;
• j) counterbalanced container handler;
• k) order-picking truck;
• l) slewing rough-terrain variable-reach truck.
