Question regarding sucker rod BOP (rod lock BOP in the catalogue of Champion X). Which API Standard applies? 6A? 16A?

Hello, I am researching what is called sucker rod BOP (Rod Lock from Oil Lift is an example). It is basically a BOP used to control wells that are doing beam or PCP pumping. API std 6A covers wellhead and tree equipment, while API 16A drillthrough equipment. This rod BOP is not explicitly covered in 6A, but seems a bit odd on 16A. Major manufacturers (Champion X) do not indicate std compliance, but I have seen some national oil co requesting some degree of compliance with BOTH 16A and 6A (but they do not state which clauses apply). Some online catalogs refer directly to 16A. The main body, flanges, bolting and polymeric material may be analyzed under 6A, but the rams and and sealing elements that clamp the rod... should be 16A?

Thanks for any insight on this!

Sucker rod BOPs are outside the scope of both API 6A and API 16A. Customers often still request conformance to one of them but this appears to be based on a misunderstanding on their part.

Normally the sucker rod rams and ram sealing elements are analyzed based on general engineering principals and without reference to 6A or 16A.
