CEN/TC 190/WG 11 - Surface inspection

This European Standard specifies a liquid penetrant testing method for castings produced by investment casting for general purposes.
NOTE   Investment casting is sometimes referred to as lost-wax casting.
This European Standard applies to all cast metals, except copper-tin and/or copper-tin-lead alloy castings, where copper is the major constituent (see EN 1982 [3]).

This European Standard specifies a magnetic particle testing method for ferro-magnetic iron and steel castings.
NOTE   An iron or steel casting is considered to be ferro-magnetic if the magnetic induction is greater than 1 T (Tesla) for a magnetic field strength of 2,4 kA/m.

This European Standard specifies methods for the examination of surface condition (roughness and surface discontinuities) of castings.
This European Standard is applicable to all cast metals and all casting processes except die casting.

This European Standard specifies a liquid penetrant testing method for castings produced in conventional sand moulds, by gravity and low-pressure die casting, except for investment castings and high-pressure die castings.
This European Standard applies to all cast metals, except copper-tin and/or copper-tin-lead alloy castings, where copper is the major constituent.

This European standard specifies the application of liquid penetrant testing to all castings (except copper-tin and/or copper-tin-lead alloy castings, where copper is the major constituent) produced by investment casting for the general purposes. This standard does not apply to aerospace investment castings.

This European Standard applies to the magnetic particle inspection of ferro-magnetic iron and steel castings. It also gives acceptance criteria through severity levels defined by the nature, the area and the dimensions of the discontinuities present. This standard applies to all ferro-magnetic castings independent of the moulding method. An iron or steel casting is considered to be ferro-magnetic if the magnetic induction is greater than 1 T (Tesla) for a magnetic field strength of 2,4 kA/m.

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.

This standard describes a method for the evaluation of casting roughness by means of visualtactile comparators.  The method is applicable to all casting processes for all cast materials. The method can be used for the assessment of castings or areas of castings in the as-cast condition (beyond removal of casting appendages, such as gates, risers and flash removal of residues of the moulding material). This method does not give a means of determining the qualityof castings by visual examination.

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.  It does not apply to investment and pressure die castings.
