General
This Standard covers overall dimensions, tolerances,
ratings, testing, and markings for wrought factory-made
buttwelding fittings in sizes NPS 1;2 through 48 (DN 15
through 1200).
1.2 Special Fittings
Fittings may be made to special dimensions, sizes,
shapes, and tolerances by agreement between the manu-
facturer and the purchaser.
1.3 Fabricated Fittings
Fabricated laterals and other fittings employing cir-
cumferential or intersection welds are considered pipe
fabrication and are not within the scope of this Standard.
Fabricated lap joint stub ends are exempt from the
above restrictions, provided they meet all the require-
ments of the applicable ASTM material specification
listed in para
