1 Scope This European Standard specifies requirements and test methods applicable to materials and seams of protective clothing against the influence of precipitation (e. g. rain, snowflakes), fog and ground humidity. The testing of rain proofness of ready made garments is excluded in this standard at this time because a separate test method for such a property is currently being prepared. 2 Normative references This European Standard incorporates by dated or undated reference, provisions from other publications. These normative references are cited at the appropriate places in the text and the publications are listed hereafter. For dated references, subsequent amendments to or revisions of any of these publications apply to this European Standard only when incorporated in it by amendment or revision. For undated references the latest edition of the publication referred to applies (including amendments).

5 Testing requirements 5.1 Testing of resistance to water penetration 5.1.1 General Testing of resistance to water penetration, in accordance with EN 20811, with an increase of hydrostatic pressure of (980 ± 50) Pa/min. 5.1.2 Number and size of specimens Number of specimens:  5 specimens for the testing of material before pretreatment;  5 specimens for the testing of the seams before pretreatment;  5 specimens for the testing of material after pretreatment by dry-cleaning and/or washing;  4 specimens for the testing after pretreatment by abrasion;  4 specimens for the testing after pretreatment by repeated flexing, i.e. 2 specimens in production direction and 2 specimens across the production direction;  4 specimens for the testing after pretreatment by fuel and oil, i.e. 2 specimens for testing with fuel and
2 specimens for testing with oil. Specimens are to be cut off from the layers as specified in Table 1 (see also annex C) and shall have a size of at least 130 mm diameter. 5.1.3 Pretreatments of outer shell material and liner or thermal liner in combination 5.1.3.1 General Separate samples will be used for each of the following pretreatments prior to testing the resistance to water penetration:
