3 Terms and definitions
For the purposes of this document, the terms and definitions given in ISO 5579 apply.
11 Foundry responsibility
Unless otherwise specified at the time of the enquiry or order, the responsibility of the manufacturer is limited to the attainment of the criteria specified in the order, in all castings, or portions of castings specifically calling for radiographic examination. Castings or portions of castings not required to be radiographically examined by the foundry shall not be subject to rejection based upon the results of any subsequent radiographic examination. Also, castings shall not be subject to rejection based upon radiographic re-examination subsequent to their acceptance on the basic of the original radiography if such examination is carried out by techniques other than those agreed upon at the time of the enquiry and order and/or in a manner different from that described in the finalized shooting sketch (see 9.2).
