Eye and face protection - Test methods - Part 3: Physical and mechanical properties (ISO 18526-3:2020)

This document specifies the reference test methods for determining the physical and mechanical
properties of protectors.
This document does not apply to any eye and face protection requirement standards which refer to
other test method standards.
Other test methods may be used if shown to be equivalent.

Augen- und Gesichtsschutz - Prüfverfahren - Teil 3: Physikalische und mechanische Eigenschaften (ISO 18526-3:2020)

Dieses Dokument legt die Bezugsprüfverfahren für die Bestimmung der physikalischen und mechanischen Eigenschaften von Augen- und Gesichtsschutzgeräten fest.
Dieses Dokument gilt nicht für etwaige Anforderungsnormen für Augen- und Gesichtsschutzprodukte, für die andere Prüfverfahren festgelegt sind.
Andere Prüfverfahren können angewendet werden, sofern ihre Gleichwertigkeit nachgewiesen ist und ihre Präzision die für das Referenzverfahren geforderte nicht übersteigt.

Protection des yeux et du visage - Méthodes d'essai - Partie 3: Propriétés physiques et mécaniques (ISO 18526-3:2020)

Le présent document spécifie les méthodes d'essai de référence pour la détermination des propriétés physiques et mécaniques des protecteurs des yeux et du visage.
Le présent document ne s'applique à aucun produit relatif à la protection des yeux et du visage pour lequel la norme d'exigences spécifie d'autres méthodes d'essai.
D'autres méthodes d'essai peuvent être utilisées si leur équivalence est démontrée et si les incertitudes de mesure qui leur sont associées n'excèdent pas celles exigées par la méthode de référence.
