(Specification)Standard Specification for Steel Castings, Surface Acceptance Standards, Magnetic Particle and Liquid Penetrant Inspection
Standard Specification for Steel Castings, Surface Acceptance Standards, Magnetic Particle and Liquid Penetrant Inspection
ABSTRACT
This specification covers steel castings, surface acceptance standards, magnetic particle and liquid penetrant inspection. Liquid penetrant inspection or magnetic particle inspection shall be used for nondestructive inspection. Personnel performing examination shall be qualified in accordance with an acceptable written procedure as agreed upon between the purchaser and manufacturer. All relevant indications shall be evaluated in terms of the acceptance criteria. Individual relevant linear and nonlinear indications exceeding the specified acceptance levels shall be considered unacceptable.
SCOPE
1.1 This specification covers acceptance criteria for the surface inspection of steel castings when nondestructively examined by magnetic particle or liquid penetrant inspection.
1.2 This specification is to be used wherever the inquiry, contract, order, or specification states that the acceptance standards for magnetic particle or liquid penetrant inspection shall be in accordance with Specification A903/A903M.
1.3 The values stated in either inch-pound units or SI units are to be regarded separately as standard. Within the text the SI units are shown in brackets. The values stated in each system are not exact equivalents; therefore each system must be used independently of the other. Combining values from the two systems may result in a nonconformance with this specification.

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.
