This standard describes a method for the evaluation of casting roughness by means of visual tactile comparators.
The method is applicable to all casting processes (except pressure die casting) 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 and removal of residues of the moulding material).
This method does not give a means of determining the quality of castings by visual examination.
However, since non-destructive testing (ultrasonic, dye penetrant etc.) is influenced by surface condition, preliminary roughness evaluation may be made using this method as an aid to subsequent non-destructive testing examination.
note:2) Visual inspection of steel castings for evaluating surface discontinuities can be done in accordance with prEN 12454.
