Active Standard ASTM F2718 | Developed by Subcommittee: F17.67
Book of Standards Volume: 08.04
1.1 This specification covers requirements and test methods for materials for a semi-structural polyethylene (PE) encapsulated cement mortar formed-in-place liner system (FIPLS) intended for the rehabilitation of water pipelines of nominal size 4 in. to 12 in. This renewal process involves installing a collapsed PE liner, folded at the time of insertion, into an existing pipeline, expanding the PE liner, and then pumping cement mortar into the annulus between the liner and the main.
1.2 The liner and cement mortar are progressively rounded by means of an air pressure propelled pig and expanded against the interior surface of the original host pipe. After rounding, the line is maintained under pressure until the cement mortar cures and the liner is completely self supporting.
1.3 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.
1.4 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.
1.5 There is no similar or equivalent ISO standard.
