This European Standard specifies a test method for the determination of the resistance of protective clothing, gloves and footwear materials to permeation by potential hazardous liquid chemicals under the condition of continuous contact. This test method is applicable to the assessment of protection against liquid chemicals that can be collected only by liquid or gaseous collecting media. This test method is not adapted for the assessment of chemical mixtures, except for aqueous solutions. This standard shall be used with the specifications given in the products standards (for examples EN 374 1 for gloves) where the following information shall be defined: - any pre-conditioning; - precise sampling (place, size, number); - associated levels of performance.
