Standard Guide for Selection, Design, and Installation of Thermoplastic Water- Pressure Piping Systems
SIGNIFICANCE AND USE
4.1 The requirements of this specification are intended to provide information to select, design and install thermoplastic, water-pressure piping systems for use outside buildings. Materials covered in this specification are Poly(Vinyl Chloride) (PVC) and Polyethylene (PE) plastic pipe fittings.
SCOPE
1.1 This guide is intended for use in the selection, design, and installation of thermoplastic water systems for use outside buildings. 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.

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.

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 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 non-conformance with the standard. 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.
ThoseIn 1.3.1, 1.3.2, and 1.3.4 the pipe standards followed by (a) are outside diameter-controlled pipes. Those followed by (b) are
inside diameter-controlled pipes.
