ISO 6530:2005规定了测量防护服材料对液体化学品（主要是低挥发性化学品）的渗透、吸收和排斥指数的测试方法。
通过该测试方法评估材料的两个级别的潜在性能，以满足针对以下情况的可能防护要求:
在最小压力下在材料表面沉积喷雾液滴直至聚结或偶尔形成小液滴；由单个低体积飞溅或低压射流造成的污染，允许有足够的时间脱下衣物或采取必要的其他行动，以消除防护服保留的化学物质对穿着者的任何危害，或者，在由于穿着者的自然运动（手臂、膝盖、肩膀处的衣物污染区域弯曲）和与污染表面接触而对衣物材料表面上的液体污染物施加压力的情况下（例如穿过喷洒过的树叶)。
ISO 6530:2005 specifies a test method for the measurement of indices of penetration, absorption and repellency for protective clothing materials against liquid chemicals, mainly chemicals of low volatility.
Two levels of the potential performance of materials are assessed by this method of testing to meet with possible requirements for protection against the following:
deposition on the surface of a material, at minimal pressure, of spray droplets up to coalescence or occasional small drips;
contamination by a single low-volume splash or low-pressure jet, allowing sufficient time to divest the clothing or take other action as necessary to eliminate any hazard to the wearer from chemical retained by the protective garment, or, in circumstances where pressure is applied to liquid contaminants on the surface of the clothing material as a result of natural movements of the wearer (flexing of contaminated areas of clothing at arms, knees, shoulders) and contact with contaminated surfaces (e.g. walking through sprayed foliage).
