    Abstract

    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.

    This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.

    1. 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:
    Acceptance levels

    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.
