Ductile Iron Pipe Research Association 7 9Ê 1 Ê*,--1, Ê --¶ In the 1991 revision of the ANSI/AWWA C 150/421.50 designs standard for Ductile iron pipe, Pressure Class des-ignations were incorporated. This raised questions from some utilities and engineers that traditionally specified Ductile iron pipe based on a Thickness Class designation.
