Rationale: AMS4943K results from an update of this specification and includes a reduction in hydrogen content and removal of an increased sample weight allowance (Table 1) (covered by ASTM E1447), use of vacuum in the first consumable melting (3.2.1), use of vacuum/inert gas furnaces (3.3.2), clarification of ultrasonic inspection requirements (3.5.1), making OD and ID surface conditions consistent with other titanium tubing specifications (22.214.171.124 and 126.96.36.199), and defining classification and test sampling requirements (4.2 and 4.3).
