The ASA, ANSI and ASME have continually refined and broadened the B16.5 standard.
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.
