scope:

This practice covers the personnel requirements, operator training, Environmental Protection Agency (EPA) Guidelines, 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 concerned with operations, maintenance, and cleaning work of Municipal Thermoplastic gravity sewer pipe.

The term high-pressure water jetting within this practice covers all water jetting, including the use of jets and hydro mechanical tooling at pressures below 2000 psi (0.69 MPa).

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

This practice applies to High-Density Polyethylene, Polypropylene, and Polyvinyl Chloride (HDPE, PP, and PVC) Thermoplastic sewer pipe manufactured in accordance with ASTM Standards. It may also be considered for use for any similar thermoplastic pipe products not covered by this list but with similar performance characteristics.

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.

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. Some specific hazards statements are given in Section 5 on Hazards/Safety.

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.
