Description / Abstract:
This specification covers perforated concrete pipe intended to
be used for underdrainage.
This specification is applicable for orders in either SI units
(M 175M) or in inch-pound units (M 175). SI units and inch-pound
units are not necessarily equivalent. Inch-pound units are shown in
brackets in the text for clarity, but they are the applicable
values when the material is ordered to M 175.
