The PDF explicitly requires a clean, dry, blast-cleaned or ground surface. Evaluating un-cleaned castings against SP-55 is invalid.
The standard defines how to evaluate surface quality. It is crucial to note that MSS SP-55 is specifically for . It does not replace radiographic (RT), magnetic particle (MT), or ultrasonic (UT) testing, but rather acts as a primary, rapid screening tool. 3. Scope of Surface Irregularities Covered
Developed by the Manufacturers Standardization Society (MSS) of the Valve and Fittings Industry, MSS SP-55 is a standard practice that provides a uniform, visual method for evaluating surface irregularities on iron and steel castings. mss sp55 standard pdf work

Metal supports used in the mold to hold cores in place, which should ideally fuse completely with the molten metal. It is crucial to note that MSS SP-55 is specifically for
The MSS SP-55 standard, titled defines acceptable and unacceptable surface conditions.
Rough, raised areas of metal formed when a portion of the mold face flakes off.
Defines the maximum allowable size and depth of various surface imperfections.
