Description:This standard specifies the method to be used for visual examination to assess surface discontinuities of steel castings produced in conventional sand moulds. A set of visual comparators  comprising replicas of actual casting discontinuities forms the basis of the assessment.
This standard does not apply to steel castings made by the resin-shell, investment and other precision moulding techniques.
This standard defines several categories of discontinuities and severity levels within each of these categories.
