Application Summary AI generated

This standard specifies the procedure for determining the ash content of pattern materials used in investment casting. It is applied in the metallurgical industry to evaluate the purity and residual inorganic content of waxes, plastics, or other pattern compounds before they are used to create ceramic shell molds. The test ensures that pattern materials do not leave excessive residue during burnout, which could compromise the quality of precision metal castings.
