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 document 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).
ISO draws attention to the possibility that the implementation of this document may involve the use of
(a) patent(s). ISO takes no position concerning the evidence, validity or applicability of any claimed
patent rights in respect thereof. As of the date of publication of this document, ISO [had/had not] received
notice of (a) patent(s) which may be required to implement this document. However, implementers are
cautioned that this may not represent the latest information, which may be obtained from the patent
www.iso.org/patents. ISO shall not be held responsible for identifying any or all
database available at
such patent rights.
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

This document was prepared by Technical Committee ISO/TC 127, Earth-moving machinery,
Subcommittee SC 2, Safety, ergonomics and general requirements.
Any feedback or questions on this document should be directed to the user’s national standards body. A

Introduction
This document provides consistent material performance requirements that can be used with all ISO/TC
127/SC 2 and ISO/TC 23/SC 15 operator protective structure standards, for example ISO 3449, ISO 3471,
ISO 10262, ISO 12117, ISO 12117-2, ISO 8082-1, ISO 8082-2, ISO 8083, and ISO 8084. These operator
protective structure standards were originally developed with the intent of having the same material
performance requirements. Over the course of revising the different operator protective structure
standards and creating new operator protective structure standards, modifications to the material
performance requirements have resulted in some inconsistencies between the material performance
requirements in these standards.
While the first edition of this document only covers material performance requirements for steel
structural members, moving the material performance requirements to a separate standard can facilitate
the development of performance for other materials such as plastic or aluminium to be included in future
revisions.
