Personal protective equipment - Safety footwear (ISO/DIS 20345:2020)

This 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. Special risks are covered by complementary job-related standards, e.g. footwear for firefighters, electrical insulating footwear, footwear protecting against chain saw injuries, chemicals, molten metal splash, and protection for motor cycle riders.

Persönliche Schutzausrüstung - Sicherheitsschuhe (ISO/DIS 20345:2020)

Diese Internationale Norm legt Grundanforderungen und (freiwillige) Zusatzanforderungen an Sicherheitsschuhe für allgemeine Zwecke fest, z. B. durch die Behandlung mechanischer Risiken, der Rutschhemmung, thermischer Risiken und ergonomischer Merkmale. Sie legt zudem Anforderungen an angepasste oder individuell gefertigte orthopädische Sicherheitsschuhe fest. Diese Norm befasst sich nicht mit der Eigenschaft hoher Sichtbarkeit aufgrund des Zusammenwirkens mit der Kleidung (z. B. die Schuhe bedeckende Hosen) und den Arbeitsplatzbedingungen (z. B. Schmutz, Schlamm).
Besondere Risiken werden in ergänzenden, auf einzelne Tätigkeiten bezogenen Normen behandelt, (z. B. Schuhe für die Feuerwehr, elektrisch isolierende Schuhe, Schutzschuhe gegen Schnitte durch Kettensägen, Schuhe zum Schutz gegen Chemikalien, Schuhe zum Schutz gegen flüssige Metallspritzer, Schutzschuhe für Motorradfahrer).

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 20345 was prepared by the European Committee for Standardization (CEN) Technical Committee

CEN/TC 161, Foot and leg protectors, in collaboration with Technical Committee ISO/TC 94, Personal

safety — Protective clothing and equipment, Subcommittee SC 3, Foot protection, in accordance with the

Agreement on technical cooperation between ISO and CEN (Vienna Agreement).

Personal protective equipment — Safety footwear
1 Scope

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

(e.g. dirt, mud).

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

molten metal splash, protection for motorcycle riders).

constitutes requirements of this document. For dated references, only the edition cited applies. For

undated references, the latest edition of the referenced document (including any amendments) applies.
