This European Standard specifies a method for determining the resistance of chemical protective clothing to penetration by jets of liquid chemicals. This European Standard is applicable to clothing which may comprise one or more items and which is intended to be worn where there is a risk of exposure to a forceful projection of a liquid chemical. This European Standard is applicable to clothing which is intended to be resistant to penetration under conditions which require total body surface cover but do not demand the wearing of gas-tight clothing. This European Standard is not applicable to permeation of liquid chemicals through materials from which the clothing is made.
