ASTM F1947-21a

Standard Practice for Installation of Folded Poly(Vinyl Chloride) (PVC) Pipe into Existing Sewers and Conduits

SIGNIFICANCE AND USE
4.1 This practice is for use by designers and specifiers, regulatory agencies, owners, and inspection organizations who are involved in the rehabilitation of non-pressure sewers and conduits.
SCOPE
1.1 This practice describes the procedures for the rehabilitation of sewer lines and conduits with nominal diameters between 4 in. and 30 in. (100 mm and 750 mm) by the insertion of folded PVC pipe, which is heated, pressurized, and expanded against the interior surface of the existing pipe with either a mechanical rounding device or steam pressure. The finished formed PVC pipe will be continuous and conform to the existing pipe. This rehabilitation process can be used in a variety of non–pressure applications, such as: sanitary sewers, storm sewers, and process piping.  
1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.  
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
