Sets out a method for determining the resistance of materials used in the manufacture of protective clothing to molten metal splash. This Standard is identical with and reproduced from ISO 9185:1990.

This International Standard describes a method for assessing the resistance of materials used in protective clothing to molten metal splash. It is important to note that good resistance of a material to a pure molten metal does not guarantee a good performance against slag.
