(1) (Modifies __.) This indicates that the material in ASME B31.1 so numbered for identification is generally applicable but is being altered, amplified, or augmented.
(2) (Replaces __.) This indicates that the material in ASME B31.1 so numbered for identification does not apply.
(3) (Reproduces __.) This indicates that the material in ASME B31.1 so numbered for identification is being identically reproduced for convenience, not for emphasis.
