This European Standard applies to the liquid penetrant testing of all castings (except copper-tin and/or copper-tin-lead alloy castings, where copper is the major constituent) produced in conventional sand moulds by gravity and low-pressure die casting, whatever their grade and the casting procedure used to produce them.
This standard does not apply to investment and pressure die castings.
