No. 99-0318 Customer Administration Printronix 14600 Myford Rd Irvine, CA 92623-9559 Dear Ms. Parham: This is in response to your letter dated November 19, 1999, Hazardous Materials Regulations (HMR; 49 CFR Parts 171-180) to requesting clarification regarding the applicability of the the transportation of accumulators. Specifically, you ask if the HMR apply to replacement accumulators not assembled in machinery and accumulators transported in assembled machinery. As provided by § 173.306 (f) (1), accumulators which are installed in assembled machinery and constructed with a burst pressure of at least five times their charged pressure at 70°F are not subject to the HMR. Accumulators, as described in $ 173.306 (f), not in assembled machinery are subject to the HMR. However, accumulators intended to function as shock absorbers, struts, gas spring, pneumatic springs or other impact or energy-absorbing devices are not subject to the HMR provided they meet the criteria specified in S : 173.306 (f) (4) . I hope this satisfies your request.
