Protective clothing — Protection against liquid chemicals — Determination of resistance of materials to penetration by liquids

Defines the characteristics of resistance of clothing, the test method for their assessment, the marking requirements. Such clothing is for use in operations with chemicals in industry, agriculture and laboratories. The purpose is to provide protection against occasional exposure to droplets or small drops, a brief exposure to a low pressure jet or a splash. Finally it is emphasized that the protection may be reduced by normal wear and tear and will probably become non-existent when the clothing is wet.
