ASTM WK56697

    New Practice for Prevent Contamination in Polyethylene Pressure Pipe

    (What is a Work Item?)

    Developed by Subcommittee: F17.26 | Committee F17 | Contact Staff Manager


    1. Scope

    1.1 This practice describes procedures required to assure the cleanliness, and thus prevent detrimental contamination, of polyethylene (PE) materials during the manufacture of polyethylene pipe used for pressure distribution or transmission of fluids. The procedures in this practice apply to the control of new material (virgin natural and color concentrate and precompounded) from receipt and to rework material from its generation by the manufacturer, including requirements for the control of material transfer system components, material preparation, and product manufacturing equipment. This practice is not applicable to products that incorporate recycled materials. A suggested plant audit form is in the Appendix. 1.2 PE compound manufacturers observe procedures to assure product quality and cleanliness and procedures that assure the cleanliness of containers such as railcars, trucks, boxes, and bags that are used to transport new material to users. However, the introduction of contamination is possible due to accidents during transport, careless handling, unauthorized tampering with railcar closures, or the like. For this reason, this practice includes procedures that apply to new materials when received by the pipe manufacturer. 1.3 This practice does not address the design or function of the PE pipe. This practice does not address material received in liquid or powder form. 1.4 Units--The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with the 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 and health practices and determine the applicability of regulatory limitations prior to use.

    This practice can be used by manufacturers to set practices. This practice can also be adopted by other ASTM product standards and purchasing and specifying entities such as industry and government.
