34、variation of 50 F (28 C) from the established limit is permissible Solidification and cooling procedures Straightening procedure, when applicable Cleaning operations Methods of inspection Radiographic inspection sampling plan, if used 4.4.2.1.1 Any of the above process control factors for which para

35、meters are considered proprietary by the vendor may be assigned a code designation. Each variation in such parameters shall be assigned a modified code designation. 4.5 Reports The vendor of castings shall furnish with each shipment a report showing the results of tests for composition of each melt

36、and stating that the castings conform to the other technical requirements. This report shall include the purchase order number, melt and lot number, AMS4290L, part number, and quantity. 4.6 Resampling and Retesting If any specimen used in the above tests fails to meet the specified requirements, dis

37、position of the castings may be based on the results of testing two additional specimens for each original nonconforming specimen. Failure of any retest specimen to meet the specified requirements shall be cause for rejection of the castings represented. Results of all tests shall be reported. 5. PR

38、EPARATION FOR DELIVERY 5.1 Identification Shall be in accordance with AMS2804. 5.1.1 Impregnated castings shall be marked “IMP“. 5.2 Packaging Castings shall be prepared for shipment in accordance with ASTM B 660 and in compliance with applicable rules and regulations pertaining to the handling, pac
