Guide Specification for Copper and Copper AlloyBuilding Piping SystemsREVISION 2(02/04/2014)ByCopper Development Association Inc.260 Madison AvenueNew York, NY 10016212/251-7200http://www.copper.org2 Copper Guide Specification

COMMENTARYThis Guide Specification was developed to aid those involved in the writing of specifications and construction documentsinvolving the use of copper and copper alloy piping system products. This Guide Specification contains basic informationon the standards related to the manufacture of copper and copper alloy copper piping system products and materials, thesizes, tempers and configurations available in accordance with these standards, the most common technologies used injoining the tube/pipe and fittings outlined in the standards, system installation requirements, and minimumrecommendations for all of the above in a variety of building piping systems.This Guide Specification contains the following parts:Part 1 – General:Information on the standards referenced throughout the Guide Specification, provisions for qualityassurance for piping system installation and requirements for the delivery, storage and handling ofmaterials referenced in the Guide Specification. The bulk of Part 1 is made up of Section 1.1, which is alist of the most common standards related to the manufacture of copper and copper alloy piping systemproducts and materials. The standards included were written or published by the following: AmericanSociety for Testing and Materials (ASTM), American National Standards Institute (ANSI), AmericanWelding Society (AWS), American Society of Mechanical Engineers (ASME), National Fire ProtectionAssociation (NFPA), Manufacturers’ Standardization Society (MSS), Compressed Gas Association (CGA),and American Society of Sanitary Engineering (ASSE International). The contents of this section areuseful in determining whether the materials/products proposed for use in the piping system aremanufactured in accordance with a nationally recognized standard, or if a component with a nationallyrecognized standard can be generically specified in its place.Part 2 – Products:Specific information on the pipes/tubes, fittings, and joining materials allowed under this GuideSpecification. The majority of this section is comprised of information regarding the composition andusage of the different joining materials allowed for joining copper and copper alloys under this GuideSpecification.Part 3 – Execution:Installation methods and procedures allowed under this Guide Specification for the installation ofcopper and copper alloy piping systems. This includes information on alternate field-fabricatedfittings/connections, requirements for piping joint construction, piping protection, and hanger andsupport spacing. This part also contains Section 3.3 – Pipe and Fitting Applications, which matches thecommon pipe/tube standards with the compatible fittings standards and options available for joiningthe two. The options outlined in this section are based on commercially available pipe/tube and fittingssizes and also consider the availability of components based on variables such as temper and scheduleor type.Part 4 – Piping Systems Applications:Minimum recommendations on pipe/tube, fittings and joints allowed for specific piping systemapplications. This Part also includes specific installation requirements as necessary for each pipingsystem application. Recommendations are included for the following piping system applications: waterdistribution piping systems (above and below ground), soil, waste and vent piping systems (above andbelow ground), storm drainage piping systems (above and below ground), hydronic heating pipingsystems (above and below ground), air conditioning and refrigeration piping systems, fuel gasdistribution piping systems (natural and LP gas), fire sprinkler piping systems, non-flammable medicalgas piping systems and medical vacuum piping systems.3 Copper Guide Specification
