Cornelius\nGayston Corporation\nDirector of Quality\n200 Advance Drive\nSpringboro, OH 45066\nReference No. 14-0147\nDear Dr. Cornelius:\nThis is in response to your July 21, 2014 letter requesting clarification of the Hazardous\nMaterials Regulations (HMR; 49 CFR Parts 171-180) applicable to the calculation of the\ntare weight of cylinders. Specifically, you seek an interpretation of § 178.35(c)(3)(vii) as it\npertains to the process by which you report the tare weight and volumetric capacity of a\nspecification cylinder during the manufacturing process.\nIn your incoming letter, you propose to determine the tare weight of the cylinder prior to\nconducting the hydrostatic testing. This information is collected and summarized by a lot\ncode and the highest tare weight (i.e. the heaviest part) would then be used to determine the\nvolumetric capacity for the entire lot of cylinders. You ask if it is permissible to gather the\ntare weight prior to hydrostatic testing.\nThe answer is yes. The HMR does not specify when in the manufacturing process the tare\nweight of the cylinder must be determined. Determining the tare weight of the cylinder\nprior to conducting the hydrostatic test is not prohibited. In addition, using the maximum\ntare weight in a specific lot as the marked tare weight is not forbidden provided that the\ntare weight and volumetric capacity measured under § 178.35(c)(3)(vii) are accurate and\nnot affected by any other test conducted on the cylinder. However, caution is advised since\nmarking the cylinder with the maximum tare weight instead of the actual weight could\nresult in cylinder underfilling, errors during requalification, or other recordkeeping issues.\nI hope this satisfies your request.\nSincerely,\nTAlenn\nroste\nT.

Our\nhydrostatic testing. This information will be collected and summarized by lot code and the highest tare\nproposal is to move the location for gathering tare weigh to the final machining operation, prior to\nweight (i.e. heaviest part) will then be used to determine the volumetric capacity for the entire lot of\ncylinders. We will still gather individual full-weight measurements post hydrostatic testing and use the\nlot-specific tare weight to determine the volumetric capacity for our cylinders. Gaston Corporation feels\nthat this will result in a method that is fair and accurate representation of our cylinders volumetric capacity\nas well as being a more efficient manufacturing process.\nRespectfully,\nChristopher A.
