scope:

This standard addresses the techniques for the inspection and requalification of composite overwrapped high pressure cylinders. The use of this standard is required in the United States by Title 49 of the U.S. Code of Federal Regulations (49 CFR) Part 180.205(f)(1), and in Canada by CSA B339, Clause 24 [6, 4]. The requalification consists primarily of an internal and external visual inspection followed by hydrostatic testing. This standard highlights those items essential for an accurate appraisal of a composite overwrapped cylinder for compressed gas service. For information on requirements of general cylinder inspection and requalification (visual inspection and hydrostatic testing), refer to the publications listed in Section 3.

It is important to be aware of the design life of the cylinder before filling or requalifying. The user or requalifier shall consult the appropriate special permit, equivalency certificate, or specification to determine the appropriate design life. The composite cylinder shall be removed from service and condemned at the termination of the cylinder design life (i.e., the appropriate period in years following the original manufacturer's test date). Failure to do so is in direct violation of federal regulations and can increase the risk to public safety.

Not all of the considerations for requalification (visual inspection and hydrostatic testing) of composite cylinders are covered in this standard. Questions regarding specific cylinders should be directed to the manufacturer.

Purpose

The purpose of this standard is to provide sufficient data and details about composite cylinders so an experienced cylinder requalifier registered with DOT, TC, or both can examine and hydrostatically test these cylinders to the requirements of the specific special permits, equivalency certificates, or specifications.
