标准范围

ISO 17491-4:20 08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方法: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该衣服。方法B:高水平喷雾试验这适用于服装不同部分之间以及服装与其他个人防护设备之间具有防喷雾连接的服装，如果适用，该服装覆盖整个身体表面，并且打算在有暴露于喷雾液体颗粒的风险时穿着。

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.
