Your questions have been paraphrased and answered below. Q1. You ask whether International Organization for Standardization (ISO) cylinders, manufactured with a country of approval other than the United States, must be retested in accordance with the Requalification of Cylinders table found in § 180.209 or the requirements for requalification of United Nations (UN) pressure receptacles specified in § 180.207. A1. As discussed on page 85388 of the final rule issued under Docket No. PHMSA-2011- 0140 (12/28/2020, 85 FR 85380) (HM-234) ISO cylinders with a country of approval of the United States or Canada must be tested in accordance with the test requirements in § 180.207 which specifies requirements for the requalification of UN pressure receptacles. ISO cylinders must be manufactured with a country of approval of the United States or Canada to be considered an approved package (See § 180.205(a)). Q2. You ask whether is it acceptable to perform an ultrasonic examination on foreign ISO cylinders (i.e., manufactured with a country of approval other than the United States or Canada) under your current retester’s certification letter and your current calibration standards manufactured for UN/ISO 9809-1,2,3 USA cylinders. <<>> A2. The answer is no. Your company’s Requalifier Identification Number (RIN) H949, authorizes: “DOT cylinder specification(s): 3A, 3AA, 3AL, UN ISO: 9809-1, 9809-2 and 9809-3 and Special Permit(s): 6557 and 14175 by the “ultrasonic” test method, in accordance with Special Permit(s): 16461, 14546 and 20831.” PHMSA retester’s certification letters authorize RIN holders testing authority for DOT approved cylinders. Your company’s RIN does not specifically authorize testing UN ISO cylinders with a country of approval other than the United States or Canada. I hope this information is helpful. Please contact us if we can be of further assistance. Sincerely, T.
