Dear Ben,

We have received your inquiry about the Hazardous Materials Regulations

http://hazmat.dot.gov/rules.htm

Periodic requalification of DOT specification cylinders is specified in §
180.209. Any cylinder not exceeding 2 inches in outside diameter is not
subject to the volumetric expansion test.

If you require further assistance, our Hazardous Materials Information
Center is staffed with regulatory specialists who can quickly answer your
questions by phone. Please do not hesitate to call, as the Information
Center is open Monday through Friday, 9 am - 5 pm E.S.T. at (800) 467-4922

Sincerely,

Kurt Eichenlaub, Hazardous Materials Specialist
