ASTM F1947-04 - 1.4.2004
 
Significance and Use

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.

 
1. Scope

1.1 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 gravity applications, such as sanitary sewers, storm sewers, and process piping.

1.2 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are provided for information purposes only.

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 and health practices and determine the applicability of regulatory limitations prior to use.
