Dear Mr. St. Amand:

In response to your letter of December 20, 1971, requesting an interpretation of Section 192.195 Protection Against Accidental Overpressuring, we offer the following:

Question: (Paraphrased) Is there any intent in 192.195 to limit the use of some types of overpressure protective devices that were previously permitted under certain conditions under the interim standards (B31.8) such as relief, monitoring, rupture discs, shut-off and series regulation?

Answer: Except as specifically provided for in Section 192.195, there is no intent to limit the type of overpressure protection device that an operator may use. The operator is free to choose the device, including those referenced by you, that will best suit his situation so long as it complies with applicable requirements of Part 192.

If you have further question, please advise.
