Quality Standard for Steel Castings for Valves, Flanges, Fittings, and Other Piping Components - Radiographic Examination Method
|Publication Date:||1 January 2013|
This Standard Practice provides methods and acceptance standards for the film method of radiographic examination of steel castings for valves, flanges, fittings, and other piping components. This Standard Practice is applicable to the initial examination of castings and toward the examination of casting repairs.
The methods contained in this Standard Practice provide uniform procedures that will produce satisfactory and consistent results upon which the acceptance standards of Section 5 may be used.
This examination guide may be used on a voluntary basis or when specified in an inquiry, contract, or order, and when mutually agreed upon by the manufacturer and the purchaser.
It is difficult to rigidly interpret radiographs to a set of acceptance standards. Consequently, there is a need for close cooperation between the manufacturer and the purchaser in applying radiographic acceptance standards.
