Standard Practice for Steel Castings, Surface Acceptance Standards, Visual Examination
The following bibliographic material is provided to assist you with your purchasing decision:
This practice covers the standard acceptance criteria for the determination of surface texture, surface roughness, and surface discontinuities of steel castings by visual examination. The acceptance levels utilize the Steel Castings Research and Trade Association (SCRATA) graded reference comparators described as follows: Level A for surface texture, Level B for nonmetallic inclusions, Level C for gas porosity, Level D for solidification discontinuities, Level E for sand expansion discontinuities, Level F for metal inserts, Level G for thermally cut surfaces, Level H for mechanically prepared surfaces, and Level J for welded surfaces.
Scope
1.1 This practice covers the acceptance criteria for the surface inspection of steel castings by visual examination. Four levels of acceptance standards are provided.
1.2 Acceptance levels utilize Steel Castings Research and Trade Association (SCRATA) graded reference comparators for the visual determination of surface texture, surface roughness, and surface discontinuities described as follows:
