Abstract

Comparisons are reported between two laboratory methods for assessing the resistance of clothing materials to splashes of molten substances. The methods, ISO DIS 9185:1986 and a modification using calorimeters, were found to rank materials in broadly the same way. The results, including the performance of clothing in industry, have shown that heat transfer occurs due to adhesion of molten substances to clothing and penetration of molten substances through clothing. Information is given on the extent of adhesion of molten iron, copper, brass, aluminum, slag, and the electrolyte used in aluminum smelting, to commonly found clothing materials in order to aid selection for specific uses. The structure of wool melton cloths to provide protection against molten iron, copper, and brass is considered.
