Причина отмены This specification covers requirements and test methods for materials of deformed PE liner intended for the rehabilitation of gravity flow and nonpressure pipelines. This application is for municipal sewage, storm water, industrial process liquids and effluents, conduit, and ducts. This renewal process involves installing a deformed liner into an existing pipeline, conduit, or duct, then reforming the liner with heat and pressure to fit tightly to the bore of the original pipeline, conduit, or duct.

Formerly under the jurisdiction of Committee F17 on Plastic Piping Systems, this specification was withdrawn in May 2018 in accordance with section 10.6.3 of the Regulations Governing ASTM Technical Committees, which requires that standards shall be updated by the end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.

Реферат

This specification covers requirements and test methods for deformed polyethylene (PE) liner for the rehabilitation of gravity flow and nonpressure pipelines. PE material shall conform to the recommended hydrostatic design basis. The process shall involve installing a deformed liner into an existing pipeline then reforming the liner to fit tightly to the bore of the original pipeline. Requirements and test methods that shall conform to this specification include workmanship, dimensions, size, environmental stress crack resistance, tensile strength, tensile elongation, flexural modulus, conditioning, referee testing, quality control testing, marking, and packaging.

1.1 This specification covers requirements and test methods for materials of deformed PE liner intended for the rehabilitation of gravity flow and nonpressure pipelines. This application is for municipal sewage, storm water, industrial process liquids and effluents, conduit, and ducts. This renewal process involves installing a deformed liner into an existing pipeline, conduit, or duct, then reforming the liner with heat and pressure to fit tightly to the bore of the original pipeline, conduit, or duct.

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. In referee decisions, inch-pound units shall be used.

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