No. 99-0042\nNational Ordnance, Munitions\nNational Technical Systems\nand Environmental Test Center\nP.O. Box 3315\nEast Camden, AR 71701\nDear Mr. Farrar:\nThis is in response to your letter of February 10, 1999, requesting clarification on the requirements for\nlithium batteries under the Hazardous Materials Regulations (HMR; 49 CFR parts 171-180).\nSpecifically you ask whether a 32 volt lithium battery must be subjected to the tests in the UN Manual\nof Tests and Criteria, specifically paragraph 38.3.4.3.2.2.3.\nThe answer is no. A lithium battery that exceeds the referenced nominal voltage is not subject to those\ntests. Such a battery would have each cell tested rather than the entire battery.\nI hope this information is helpful.\nSincerely,\nDelmer F. Billings\nChief, Standards Development\nOffice of Hazardous Materials Standards\n173.185\n990042\n09062059433","truncated":false,"body_characters":1035}
