Protective clothing - Test methods for clothing providing protection against chemicals - Part 4 : determination of resistance to penetration by a spray of liquid (spray test)
This document specifies the test method for determining the resistance of chemical protective clothing to penetration by sprays of liquid chemicals at two different levels of intensity:a) Method A: low-level spray test. This is applicable to clothing that covers the full body surface and is intended to be worn when there is a potential risk of exposure to small quantities of spray or accidental low-volume splashes of a liquid chemical.b) Method B: high-level spray test. This is applicable to clothing with spray-tight connections between different parts of the clothing and, if applicable, between the clothing and other items of personal protective equipment, which covers the full body surface and which is intended to be worn when there is a risk of exposure to sprayed liquid chemical.This document does not apply to chemical permeation resistance of the materials from which the chemical protective clothing is made.

ISO 17491-4:2008 specifies methods for determining the resistance of chemical protective clothing to penetration by sprays of liquid chemicals at two different levels of intensity: Method A: low-level spray test. This is applicable to clothing that covers the full body surface and which is intended to be worn when there is a potential risk of exposure to small quantities of spray or accidental low volume splashes of a liquid chemical. Method B: high level spray test This is applicable to clothing with spray-tight connections between different parts of the clothing and, if applicable, between the clothing and other items of personal protective equipment, which covers the full body surface and which is intended to be worn when there is a risk of exposure to sprayed particles of liquid.
Le présent amendement concerne une méthode d'essai pour la détermination de l'étanchéité aux brouillards d'un vêtement de protection contre les produits chimiques de type 4 (les coutures entre les différentes parties du vêtement et, le cas échéant, entre le vêtement et les autres équipements de protection individuelle étant étanches) et de type 6 (vêtements de protection aux performances limitées). Il vise à apporter des modifications en 8.2 en vue de permettre un meilleur étalonnage de l'alignement des buses de pulvérisation et d'assurer que seules, des unités SI sont utilisées (de " bar " en " kPa ").
