No.: 17-0059 UPS Aircraft Maintenance Hangar UPS Hydrostatic Shop 750 Grade Lane Louisville, KY 40213 Dear Mr. Stewart: This is in reference to your March 9, 2007 letter in which you again ask about possible tolerance requirements for the permanent expansion reading for the calibrated cylinder. use a calibrated cylinder or other approved method to verify the accuracy of the test As stated in my February 15, 2007 letter (ref. No.: 07-0002), the cylinder requalifier must verified as accurate within =1.0% of the calibrated cylinder's pressure and the equipment system. When the calibrated cylinder is pressurized, the test equipment must be pressure is released, this calibration process requires that the calibrated cylinder exhibit no corresponding expansion value shown on the cylinder calibration certificate. When the permanent expansion as specifically stated in § 180.205(g)(4). I hope this information is helpful. Please contact us if you have additional questions. Sincerely yours, Hattie L.

Hattie Mitchell, Chief Washington, DC 20590 Ref. No.: 07-0002 Dear Ms. Mitchell: Thank you for your response dated February 15, 2007. However, it appears that your interpretation of 49 CFR 180.205 (g)(4) contradicts the definitions of the required! accuracy and resolution of the device, as detailed in 49 CFR180.205 paragraphs (g)(2) and (g)(3)(ii). It would be extremely beneficial to get a written definition of the tolerance requirements of the device in order for our operations to fully comply with the regulations. This is the fourth time that I have questioned this "double standard" on the tolerance requirements of the device that do not pertain to certain readings (i.e. the permanent expansion reading of the calibrated cylinder). Again please reading to which the stated tolerance requirements do not apply, please provide the tolerance clarify specifically when the stated tolerances apply, and when they do not apply. And for any requirement for that reading. I was unable to determine the tolerance requirement for the permanent expansion reading based on the letter you provided. According to your letter the calibrated cylinder must show no permanent expansion. "When the 'pressure' [I believe you mean 'expansion' ] fails to return to zero (0) cc, the test system has not pressure is released, the EID must show (0)cc." Does that mean 0.Occ? You said, "If the proven to be accurate." This appears to contradict the first sentences in this parag: aph. (g)(4) The test equipment must be verified to be accurate within < plus- minus>1.0% of the calibrated cylinder's pressure and corresponding expansion values. This may be accomplished by bringing the pressure to a value shown on the calibration certificate for the calibrated cylinder used and verifying that the resulting total expansion is within splus-minus- 1.0% of the may be demonstrated by bringing the total expansion to a known value on the this paragraph (g) to an authorized inspector on any day that it retests cylinders. A retester must maintain calibrated cylinder certificates in conformance with Sec. 180.215(b)(4). 1 <<>> Questions: 1. Are you stating that the tolerances in 49 CRF 180.205 (g)(4) should be 0.0% not +1.0%? 2. If the EID is allowed ‡1.0% accuracy, and the Calibrated cylinder is used to prove this accuracy (+1.0% of the total expansion value of the Calibrated Cylinder), then according to 49 CFR 180.205 paragraph (g)(3)(ii) and 49 CFR180.205 paragraphs (g)(4), what are the tolerance requirements of the device that do not pertain to certain readings (i.e. the permanent expansion reading of the calibrated cylinder). 3. According to 180.205(g)(2) and (3), the EID is required to have a readability to within according to your letter, the EID must show zero (Occ) permanent expans on, in other 1% of the Total Expansion, and an accuracy of +1.0% of the Total Expansion. However, words †0.0% tolerance. Please answer the following questions specifically and explain your answers: than the device, itself, is required to have? (i.e. 0.Occ Permanent Expansion How can we be held to an accuracy and readability requirement that is higher reading for a device that is allowed +1.0% deviation.) readings would not even be seen on a system using a burette. On a burette type Why are we being penalized for using higher quality equipment? These machine, the increments would be 0.5cc, and the operator would record 0.0cc quality, digital equipment that these readings can even be detected. These for anything less than 0.5cc. It is only because we have invested in higher the device, and would never be seen on the old burette type equ pment. This readings are smaller than the required resolution and accuracy requirements of lack of understanding of technical specifications for resolution and accuracy by PHMSA is penalizing users who invest in higher quality equipment. If our for 0.001 cc deviations? How far are you going to take this fool shness? machine was capable of reading in 0.001 cc increments, would you penalize us The following information quantifies the calibration of our high precision test system capable of reading to 0.1cc through its full range, and the associated days in question. The information also verifies the system was in tolerance according the to 49 CFR180.205 paragraph (g)(3)(ii) and 49 CFR180.205 paragraphs (g)(4). <<>> 49 CFR 180.205 (g)(2) The pressure indicating device of the testing apparatus must permit reading of pressures to within 1% of the minimum prescribed test pressure. • 1 RECORTEST/OPEN (A)System Components research and development in the field of computer controlled hydrostatic test systems.
