Application Summary AI generated

This standard specifies the cooling curve method for determining the melting point of pattern materials used in investment casting. It is applied in foundries and material testing laboratories to ensure consistent thermal properties of wax or plastic patterns before shell mold production. The method is critical for controlling dimensional accuracy and surface quality in precision casting of metal parts.
