    Rationale

    Fitting dimensions are given for sizes up to NPS-4, but little guidance is given for butt fusion fittings larger than NPS-4. While some dimensions of fabricated miter fittings are controlled indirectly by the pipe dimension tables, manufactured fittings are not. Adding a paragraph stipulating that butt fusion fittings must comply with minimum wall thickness and out-of-roundness requirements would help ensure that all butt fusion fittings comply with F2389.
