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: ASurface Texture BNonmetallic Inclusions CGas Porosity DSolidification Discontinuities ESand Expansion Discontinuities FMetal Inserts GThermally Cut Surfaces HMechanically Prepared Surfaces JWelded Surfaces 1.3 Descriptions of terms related to casting discontinuities are in Section 2. 1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. |
