Scope

This standard is suitable for measuring the thermal deformation of investment casting mold materials. Expressed by the amount of sagging of the cantilever extension end of the specimen after being kept at a fixed temperature for 2 hours [formula] (mm). It is used to measure the ability of the mold material to resist softening and deformation when heated.
