Specifies requirements for water vapour permeable and non-water vapour permeable coated fabrics, suitable for use in the construction of water penetration resistant clothing

This British Standard specifies the requirements for water vapour permeable, and non-water vapour permeable coated fabrics, suitable for use in the construction of water penetration resistant clothing. This standard does not address the method of fabrication of the garment. However, the physical requirements attributed to water penetration resistance of the final garment should in no way be inferior to those listed for the coated fabric.

A guide to the cleaning of soiled garments is included in Annex I as it is felt that this is more of a property of the coated fabric than that of the garments.

NOTE The coding system applicable to the coating polymer(s) employed in the manufacture of these coated fabrics is given in Table 1.

Table 2 gives codes to distinguish the possible application of the materials but does not indicate a performance rating.
