SR EN 368:1997

This European Standard is concerned with the application of the described method of test, usually with chemicals of low volatility. Clothing made of these materials is not for use as the sole means of protection where resistance to permeation by chemicals at the molecular level (see EN 369) is essential and where a complete barrier to liquid (or gaseous chemicals) is required (e.g. risk of exposure to massive and forceful discharges of concentrated liquid chemicals). Clothing which has been developed from materials selected by this method of test should be used therefore only in well-defined circumstances when an evaluation of the finished item has indicated an acceptable level of performance (e.g. in laboratory and field testing of a garment, consideration of exposure levels to specified chemicals etc.). Two levels of the potential performance of materials are assessed by the method of test to meet with possible requirements for protection against: a) deposition on the surface of a material, at minimal pressure, of spray droplets up to coalescence or occasional small drips
