The B148 is covered by MSS SP 80 and PT under B16.24 which covers copper alloy and for the ductile iron casting A 536 refer B16.42 and may be replaced with A 395 or can apply the PT method defined in that standard. As I do not have the latest version of the standard in my hand, you may verfiy the same.
