This specification covers the procedures for approval of products of premium-quality titanium alloys and the controls to be exercised in producing such products.

This specification requires approved sources.

This specification has been used typically for parts fabricated from titanium alloys which require approval of the product and facets of its production to ensure that production lots are of the same metallurgical quality, are produced by the same basic procedures as the products originally qualified, and for parts subjected to rigid inspection standards throughout manufacture from ingot to finished part, but usage is not limited to such applications.
