No.: 07-0002\nDear Ms. Mitchell:\nThank you for your response dated February 15, 2007. However, it appears that your\ninterpretation of 49 CFR 180.205 (g)(4) contradicts the definitions of the required! accuracy and\nresolution of the device, as detailed in 49 CFR180.205 paragraphs (g)(2) and (g)(3)(ii). It would\nbe extremely beneficial to get a written definition of the tolerance requirements of the device in\norder for our operations to fully comply with the regulations. This is the fourth time that I have\nquestioned this \"double standard\" on the tolerance requirements of the device that do not pertain\nto certain readings (i.e. the permanent expansion reading of the calibrated cylinder). Again please\nreading to which the stated tolerance requirements do not apply, please provide the tolerance\nclarify specifically when the stated tolerances apply, and when they do not apply. And for any\nrequirement for that reading. I was unable to determine the tolerance requirement for the\npermanent expansion reading based on the letter you provided.\nAccording to your letter the calibrated cylinder must show no permanent expansion. \"When the\n'pressure' [I believe you mean 'expansion' ] fails to return to zero (0) cc, the test system has not\npressure is released, the EID must show (0)cc.\" Does that mean 0.Occ? You said, \"If the\nproven to be accurate.\" This appears to contradict the first sentences in this parag: aph.\n(g)(4) The test equipment must be verified to be accurate within < plus-\nminus>1.0% of the calibrated cylinder's pressure and corresponding\nexpansion values. This may be accomplished by bringing the pressure to a\nvalue shown on the calibration certificate for the calibrated cylinder used and\nverifying that the resulting total expansion is within splus-minus- 1.0% of the\nmay be demonstrated by bringing the total expansion to a known value on the\nthis paragraph (g) to an authorized inspector on any day that it retests\ncylinders. A retester must maintain calibrated cylinder certificates in\nconformance with Sec. 180.215(b)(4).\n1\n\n<<<PAGE 3>>>\n\nQuestions:\n1. Are you stating that the tolerances in 49 CRF 180.205 (g)(4) should be 0.0% not +1.0%?\n2. If the EID is allowed ‡1.0% accuracy, and the Calibrated cylinder is used to prove this\naccuracy (+1.0% of the total expansion value of the Calibrated Cylinder), then according\nto 49 CFR 180.205 paragraph (g)(3)(ii) and 49 CFR180.205 paragraphs (g)(4), what are\nthe tolerance requirements of the device that do not pertain to certain readings (i.e. the\npermanent expansion reading of the calibrated cylinder).\n3. According to 180.205(g)(2) and (3), the EID is required to have a readability to within\naccording to your letter, the EID must show zero (Occ) permanent expans on, in other\n1% of the Total Expansion, and an accuracy of +1.0% of the Total Expansion. However,\nwords †0.0% tolerance. Please answer the following questions specifically and explain\nyour answers:\nthan the device, itself, is required to have? (i.e. 0.Occ Permanent Expansion\nHow can we be held to an accuracy and readability requirement that is higher\nreading for a device that is allowed +1.0% deviation.)\nreadings would not even be seen on a system using a burette.
