CGA C-6

This standard provides cylinder users (requalifiers, owners, fillers, operators, etc.) with criteria to accept, reject, and condemn steel compressed gas cylinders. This standard does not cover all circumstances for each individual cylinder type and condition of lading.

Suggestions contained in this standard do not apply to cylinders manufactured under specification DOT-3HT, CTC-3HT, or TC-3HTM. Because of the special provisions of this specification, separate recommendations covering service life and standards for visual inspection of these cylinders are contained in CGA C-8, Standard for Requalification of DOT-3HT, CTC-3HT, and TC-3HTM Seamless Steel Cylinders.

For cylinders manufactured under specification DOT-8, DOT-8AL, CTC-8, CTC-8AL, CTC-8WC, TC-8WM, or TC-8WAM, see CGA C-13, Standard for Periodic Visual Inspection and Requalification of Acetylene Cylinders.

For aluminum alloy cylinders, see CGA C-6.1, Standard for Visual Inspection of High Pressure Aluminum Alloy Compressed Gas Cylinders; CGA C-6.2, Standard for Visual Inspection and Requalification of Fiber Reinforced High Pressure Cylinders; and CGA C-6.3, Standard for Visual Inspection of Low Pressure Aluminum Alloy Compressed Gas Cylinders.
