Footwear protecting against chemicals - Part 3: Requirements for prolonged contact with chemicals

This European Standard specifies requirements for footwear intended to protect the wearer from a
prolonged continuous contact (more than 1 hour) with specific chemicals.
Degradation and permeation by chemicals are addressed in this standard. Other requirements are
covered by reference to EN ISO 20345, 20346 or 20347 as appropriate.

Schuhe zum Schutz gegen Chemikalien - Teil 3: Anforderungen für anhaltenden Kontakt mit Chemikalien

Diese Europäische Norm legt Anforderungen an Schuhwerk fest, das für den Schutz des Trägers vor anhaltendem, durchgehendem Kontakt (länger als 1 h) mit spezifischen Chemikalien vorgesehen ist.
Materialermüdung und Durchdringung durch Chemikalien werden in dieser Norm behandelt. Andere Anforderungen sind durch Verweisung auf EN ISO 20345, EN ISO 20346 bzw. EN ISO 20347, sofern zutreffend, abgedeckt.

Chaussure protégeant contre les produits chimiques - Partie 3 : Exigences pour les contacts prolongés avec les produits chimiques

La présente Norme européenne spécifie les exigences relatives aux chaussures destinées à protéger l’utilisateur d’un contact continu prolongé (plus d’une heure) avec des produits chimiques spécifiques.
La dégradation par des produits chimiques et la perméation de produits chimiques sont traitées dans la présente norme. D’autres exigences sont couvertes par une référence à l’EN ISO 20345, 20346 ou 20347, selon le cas.

Obutev za varovanje pred kemikalijami - 3. del: Zahteve za podaljšan stik s kemikalijami

Ta evropski standard določa zahteve za obutev, namenjeno za zaščito uporabnika pred podaljšanim neprekinjenim stikom (več kot 1 uro) s specifičnimi kemikalijami.
V tem standardu sta obravnavana razgradnja in prepustnost kemikalij. Druge zahteve so zajete s sklicevanjem na standarde EN ISO 20345, 20346 ali 20347, kot je ustrezno.

O The applicability of a requirement to a particular classification is indicated in the table by the following. X

indicates that 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

indicates that if the component part exists, the requirement shall be met. Note1 The absence of X or O indicates that no requirement is met. Note2 For class II footwear, it is usual to have no insole present. However, if a removable insock is used, Table 3 is applicable, only chromium VI and pH requirements are fulfilled for leather materials. Note3 Stockings covering the last before the moulding process are not considered as a lining. SIST EN 13832-3:2019
