Guide Specifications on Plumbing

This Guide Specification was developed to aid those involved in the writing of specifications and construction documents involving the use of copper and copper alloy piping system products. This Guide Specification contains basic information on the standards related to the manufacture of copper and copper alloy piping system products and materials, the sizes, tempers and configurations available in accordance with these standards, the most common technologies used in joining the tube/pipe and fittings outlined in the standards, system installation requirements, and minimum recommendations for all of the above in a variety of building piping systems.

This Guide Specification is organized into four sections and a brief overview of the contents of each section is given below. To view the complete section, click on Read More under each section. 

This Guide Specification is also available in Microsoft Word format and in Acrobat PDF format.

Information on the standards referenced throughout the Guide Specification, provisions for quality assurance for piping system installation and requirements for the delivery, storage and handling of materials referenced in the Guide Specification. The bulk of Part 1 is made up of Section 1.1, which is a list of the most common standards related to the manufacture of copper and copper alloy piping system products and materials. The standards included were written or published by the following:

  • ASTM International (ASTM - formerly American Society for Testing and Materials)
  • American National Standards Institute (ANSI)
  • American Welding Society (AWS)
  • ASME International (ASME - formerly American Society of Mechanical Engineers)
  • National Fire Protection Association (NFPA)
  • Manufacturers' Standardization Society (MSS)
  • Compressed Gas Association (CGA)
  • ASSE International (ASSE - formerly American Society of Sanitary Engineering)

The contents of this section are useful in determining whether the materials/products proposed for use in the piping system are manufactured in accordance with a nationally recognized standard, or if a component with a nationally recognized standard can be generically specified in its place.
