GENERAL NOTE: Dimensions are in millimeters.

NOTES:
(1) Class 2000 and DN6 Class 6000 couplings, half couplings, and caps are not included in this Standard.
(2) Dimensions B is minimum length of perfect thread. The length of useful thread (B plus threads with fully formed roots and flat crests) shall not be less than L 2 (effective length of external thread) required by
American National Standard for Pipe Threads (ANSI/ASME B1.20.1). See Section 6.3.
