There are currently three overlapping polypropylene corrugated standards (F2764, F2881 and F3219) that although address different applications are manufactured with the same equipment. This revision to F2764 will align all the minimum inside diameters to the same values as those of the other two standards. The most widely used standard is F2881, so to minimize any impact to the users, F2764 will be modified to align with it.
