Bibliography

Describes procedures for the inspection, testing and acceptance of seamless steel tube and tubestock for aerospace use.

This British Standard specifies procedures for the inspection, testing and acceptance of seamless steel tube and tubestock for aerospace use. The standard is applicable to material specifications in the British Standard Aerospace T series and also to other British Standard material specifications for seamless steel tubes and tubestock which are suitable for aerospace use.
