标准范围

本文件规定了测定化学防护服对两种不同强度水平的液体化学品喷雾渗透的抵抗力的试验方法:A）？方法A:低空喷雾试验。这适用于覆盖整个身体表面的衣服，并且打算在存在暴露于少量喷雾或意外低体积液体化学品的潜在风险时穿着。b）？方法B:高位喷雾试验。这适用于在服装的不同部分之间以及（如果适用的话）在服装和个人防护设备的其他物品之间具有防喷连接的服装，其覆盖整个身体表面并且旨在当存在暴露于喷雾的液体化学品的风险时穿着。本文件不适用于制造化学防护服的材料的耐化学渗透性。

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.
