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.
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.
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 1.3.3 to the extent applicable. Those pipe standards followed by (a) are outside diameter-controlled pipes. Those followed by (b) are inside diameter-controlled pipes.
