Founding. Visual examination of surface discontinuities. Steel sand castings
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(1) 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.
