Dear Ms.  Parham:

This is in response to your letter dated November 19, 1999, requesting clarification regarding the applicability of the Hazardous Materials Regulations (HMR; 49 CFR Parts 171-180) to 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 701F 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 § 173.306(f)(4).

I hope this satisfies your request.

Sincerely,

 

John A. Gale
