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 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 database available at
www.iso.org/patents. ISO shall not be held responsible for identifying any or all 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 www.iso.org/iso/foreword.html.
This document was prepared by Technical Committee ISO/TC 127, Earth-moving machinery, Subcommittee
SC 2, Safety, ergonomics and general requirements, in collaboration with the European Committee for
Standardization (CEN) Technical Committee CEN/TC 151, Construction equipment and building material
machines - Safety, in accordance with the Agreement on technical cooperation between ISO and CEN (Vienna
Agreement).
This third edition cancels and replaces the second edition (ISO 6683:2005), which has been technically
revised.
The main changes are as follows:
— introduction has been added;
— testing force has been modified to include an additional force when a seat system has a mass of applicable
seat components greater than 70 kg;
— TSIP has been introduced;
— informative Annex A listing the applicable requirements from SAE J386:2022 for seat-belt assembly
components has been introduced.
Any feedback or questions on this document should be directed to the user’s national standards body. A

Introduction
The testing of seat-belt assemblies and seat-belt anchorages is aimed at keeping the seat-belted occupant
within the operator protective structure in case of accidental overturning during operation.
This document enables a machine's seat-belt assembly and seat-belt anchorages to be tested by the application
of static loads that simulate the actual loads which can be imposed on them when the machine overturns.
This document defines performance requirements for anchorages taking into account the different seat’s
configurations. A seat-belt assembly that meet the requirements of UNECE R16:2000, Clause 6, but excluding
6.4 of that regulation, or a seat-belt assembly complying with the requirements of SAE J386:2022 is deemed
to comply with the requirements in Clause 4 of this document.
NOTE The requirement in Clause 4 of this document is normally the responsibility of the seat-belt assembly
manufacturer.
This document is a type-B standard as stated in ISO 12100.
This document is of relevance, in particular, for the following stakeholder groups representing the market
players with regard to machinery safety:
— machine manufacturers (small, medium and large enterprises);
— health and safety bodies (regulators, accident prevention organisations, market surveillance, etc.).
Others can be affected by the level of machinery safety achieved with the means of the document by the
above-mentioned stakeholder groups:
— machine users/employers (small, medium and large enterprises);
— machine users/employees (e.g. trade unions, organizations for people with special needs);
— service providers, e.g. for maintenance (small, medium and large enterprises);
— consumers (in case of machinery intended for use by consumers).
The above-mentioned stakeholder groups have been given the possibility to participate at the drafting
process of this document.
In addition, this document is intended for standardization bodies elaborating type-C standards.
The requirements of this document can be supplemented or modified by a type-C standard.
For machines which are covered by the scope of a type-C standard and which have been designed and built
according to the requirements of that standard, the requirements of that type-C standard take precedence.
