【Test Principle】:
A certain mass of molten metal is poured onto a specimen placed at an angle, and the damage to the specimen is evaluated by recording the change in the PVC film attached to the back of the specimen after pouring. According to the test results, calculate the metal pouring quality and evaluate the protection level of the specimen.
