ASTM F645 - 18b

Standard Guide for Selection, Design, and Installation of Thermoplastic Water- Pressure Piping Systems

Status : Current   Published : November 2018



1.1 This guide is intended for use in the selection, design, and installation of thermoplastic water-pressure piping systems. For specific projects, a thorough review of this guide is recommended for the purpose of selecting specific materials, methods of joining, system design factor, and any special procedures deemed necessary to assure a satisfactory system.

Note 1:  Comprehensive information on the selection, design, joining, system design factors, installation and special products and piping systems for pressurized water and other specialized applications is available in the PPI Handbook of Polyethylene Pipe and from other domestic and International sources such as PE compound and product manufacturers and trade associations.

1.2 It is recommended that governing codes and project specifications be consulted prior to the use of this guide. Nothing in this guide should be construed as recommending practices or systems at variance with governing codes and project specifications.

1.3 The pipe, fittings, and joining materials shall meet the requirements of one or more of the following component product standards listed in 1.3.1 through 1.3.4 to the extent applicable. In 1.3.1, 1.3.2, and 1.3.4 the pipe standards followed by ( a) are outside diameter-controlled pipes.

1.3.1  For poly(vinyl chloride) (PVC) plastic piping components: 

[This table has been removed.]

1.3.2  For Chlorinated Poly(Vinyl chloride) (CPVC) plastic piping components: 

[This table has been removed.]

1.3.3  Standards for polyethylene (PE) plastic piping: 

[This table has been removed.]

1.3.4  For poly(vinyl chloride) (PVC) Plastic Piping Components Issued By the American Water Works Association: 

[This table has been removed.]

1.3.5 Pipes with wall thicknesses less than 1.50 mm (0.06 in.) are not recommended.

1.4  Other Joining Devices—Joining devices other than those covered by the listed standards may be selected by the user on the basis of his own engineering evaluation and service experience.

1.5 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 non-conformance with the standard.

1.6  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.

1.7  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.
