API 590 vs ASME B16.48

API 590 vs ASME B16.48

Good afternoon all. I am updating a database for our company and would like some clarification. Does B16.48 supersede all of the API STD 590 dimensions? I've looked through the forums and a few websites and it seems like it does but some companies still use the 590 code. Specific clarification: Say we needed a blank for an API 15k 3-1/16, would we use 590 or would we use B16.48?
