The B16.5 standard was first published by ANSI in 1973. Prior to that it was an ASA standard. In 1996 the standard changed to ASME B16.5. For 10 years prior to the change, the standard included both and was listed as ANSI/ASME B16.5.

So what's the difference? The answer is there is no difference. The ASA, ANSI and ASME have continually refined and broadened the B16.5 standard. I'm sure there is a committee working on future enhancements right now.

The current and correct standard is ASME B16.5. ANSI B16.5 is common industry lingo and is still referred to extensively by architects, engineers, manufacturers and suppliers. And although the ANSI B16.5 standard does not technically exist, it its understood as another way to say ASME B16.5.
