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

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

This International Standard specifies basic and additional (optional) requirements for safety footwear

used for general purpose. It includes, for example, mechanical risks, slip resistance, thermal risks,

ergonomic behaviour. It also specifies requirements for orthopaedic customized or individual

manufactured orthopaedic safety footwear. This standard does not cover the property of high visibility

because of interaction with the clothing (e.g. trousers cover the footwear) and work area conditions

Special risks are covered by complementary job-related standards (e.g. footwear for firefighters,

electrical insulating footwear, protection against chain saw injuries, protection against chemicals and
