Причина отмены This practice describes the procedures for the rehabilitation of sewer lines and conduits (4 to 15 in. diameter) by the insertion of a folded PVC pipe, which is heated, pressurized, and expanded against the interior surface of an existing pipe with either a mechanical rounding device or steam pressure. The finished PVC pipe will be continuous and conform to the existing conduit. This rehabilitation process can be used in a variety of non–pressure applications, such as: sanitary sewers, storm sewers, and process piping.

Formerly under the jurisdiction of Committee F17 on Plastic Piping Systems, this practice was withdrawn in February 2019 in accordance with section 10.6.3 of the Regulations Governing ASTM Technical Committees, which requires that standards shall be updated by the end of the eighth year since the last approval date.
