The vendor of sheet shall furnish with each shipment a report showing the results of tests for composition of each heat and for hydrogen content, tensile properties when determined, and surface contamination of each lot, and stating that the sheet conforms to the other tech

30、nical requirements. This report shall include the purchase order number, heat and lot numbers, AMS4932C, size, and quantity. 4.5 Resampling and Retesting If any specimen used in the above tests fails to meet the specified requirements, disposition of the sheet may be based on the results of testing

31、three additional specimens for each original nonconforming specimen. Failure of any retest specimen to meet the specified requirements shall be cause for rejection of the sheet represented. Results of all tests shall be reported. 5. PREPARATION FOR DELIVERY 5.1 Identification Each sheet shall be mar

NOTES 8.1 A change bar (l) located in the left margin is for the convenience of the user in locating areas where technical revisions, not editorial changes, have been made to the previous issue of this document. An

37、 (R) symbol to the left of the document title indicates a complete revision of the document, including technical revisions. Change bars and (R) are not used in original publications, nor in documents that contain editorial changes only. 8.2 An oxygen rich layer, such as alpha case, is hard and britt

38、le and results in marked lowering of ductility of the product. 8.3 Terms used in AMS are clarified in ARP1917. 8.3.1 Terminology relating to titanium microstructures is presented in AS1814. 8.4 Dimensions and properties in inch/pound units and the Fahrenheit temperatures are primary; dimensions and

39、properties in SI units and the Celsius temperatures are shown as the approximate equivalents of the primary units and are presented only for information. 8.5 Purchase documents should specify not less than the following: AMS4932C Size of sheet desired Quantity of sheet desired Microstructure and tensile testing, if required (See 4.2.2).
