Redline Standard: Standard Practice for Cleaning of Vitrified Clay Sanitary Sewer Pipelines

ASTM C1920

Scope

1.1 This practice covers the personnel requirements, operator training, operating procedures, and recommended equipment performance/design for the proper operation of pressure water-jet cleaning and cutting equipment as normally used by municipalities and contractors tasked with operations, maintenance, cleaning, and pre-rehabilitation cleaning work of vitrified clay mainline sewer pipe.

1.2 The term “high-pressure water jetting” covers all water jetting, including the use of jets and hydromechanical tooling at pressures above 2000 psig (0.69 MPa).

1.3 This practice covers the “high-pressure water jetting” of vitrified clay pipe and should not be applied to other pipe and pipe lining materials without evaluating the recommended cleaning procedure from the manufacturer to avoid damage.

1.4 Units—The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.

1.5 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.

1.6 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.
