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).

within the classification, e.g. pH value of leather components. This does not mean that other materials are pre-
cluded from use. O means that if the component part exists, the requirement shall be met. The absence of X or O
indicates that there is no requirement.
NOTE 2 For class II footwear, it is usual to have no insole present. However, if a removable insock is used,
Table 3 is not applicable; only chromium VI and pH requirements are fulfilled for leather material.

SIST EN ISO 20346 : 2014
Osebna varovalna oprema – Varovalna obutev
Predgovor k mednarodnemu standardu
ISO (Mednarodna organizacija za standardizacijo) je svetovna zveza nacionalnih organov za standarde
(članov ISO). Mednarodne standarde ponavadi pripravljajo tehnični odbori ISO. Vsak član, ki želi
delovati na določenem področju, za katero je bil ustanovljen tehnični odbor, ima pravico biti zastopan v
tem odboru. Pri delu sodelujejo tudi mednarodne vladne in nevladne organizacije, povezane z ISO. V
vseh zadevah, ki so povezane s standardizacijo na področju elektrotehnike, ISO tesno sodeluje z
Mednarodno elektrotehniško komisijo (IEC).
Postopki, uporabljeni pri pripravi tega dokumenta, in predvideni postopki za njegovo vzdrževanje so
opisani v 1. delu Direktiv ISO/IEC. Posebna pozornost naj se nameni različnim kriterijem odobritve,
potrebnim za različne vrste dokumentov ISO. Ta dokument je bil zasnovan v skladu z uredniškimi pravili
direktiv ISO/IEC, 2. del (glej www.iso.org/directives).
Opozoriti je treba na možnost, da so lahko nekateri elementi tega dokumenta predmet patentnih pravic.
ISO ne prevzema odgovornosti za identifikacijo nekaterih ali vseh takih patentnih pravic. Podrobnosti o
morebitnih patentnih pravicah, identifiranih med pripravo tega dokumenta, bodo navedene v uvodu in/ali
na seznamu patentnih izjav, ki jih je prejela organizacija ISO (glej www.iso.org/patents).
Vsakršna trgovska imena, uporabljena v tem dokumentu, so informacije za uporabnike in ne pomenijo
podpore blagovni znamki.
Za razlago pomena specifičnih terminov in izrazov ISO, povezanih z ugotavljanjem skladnosti, ter
informacije o tem, kako ISO upošteva načela WTO o tehničnih ovirah pri trgovanju (TBT), glejte
naslednjo povezavo: Foreword – Supplementary information (Predgovor – Dodatne informacije).

Cor.1:2005 in ISO 20346:2004/Cor. 2:2006.
Spremembe med to izdajo in izdajo iz leta 2004 so naslednje:
– odpornost proti zdrsu je prestavljena iz dodatka A v glavno besedilo (5.3.5);
– zahteve za predel pete (5.2.3) so bolj specifične;
– zahteve za korozijsko odpornost kovinskih zaščitnih kapic (5.3.2.5.1) so nekoliko spremenjene;
– dodana je točka Neškodljivost (5.3.6);
– zahteva za vsebnost kroma VI je natančno določena;
– vključena je zahteva za odpornost podloge predela pete proti obrabi;
– zahteve za odpornost proti predrtju so usklajene s standardom EN 12568;
– v dodatek A je vključena nova vrsta obutve »Hibridna obutev«.

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.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
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.
ISO 20346 was prepared by Technical Committee ISO/TC 94, Personal safety - Protective clothing and
equipment, Subcommittee SC 3, and by Technical Committee CEN/TC 161, Foot and leg protectors in
collaboration.
This second edition cancels and ISO 20346:2004 which has been technically revised.

NOTE The applicability of a requirement to a particular classification is indicated in this table by the
following:
X the requirement shall be met. In some cases the requirement relates only to particular materials
within the classification - e.g. pH value of leather components. This does not mean that other
materials are precluded from use.
O if the component part exists, the requirement shall be met.
The absence of X or O indicates that there is no requirement.
^ means that it is obligatory that one of the three slip resistance requirements shall be chosen.
