1.1''This classification covers various types of seamless copper and copper alloy2 pipe and tube used for water service, distribution, and drainage. It is not a specification for the various types and alloys.

1.2''This classification uses the standard copper designations developed and used by the copper industry.

1.3''This classification makes no attempt to differentiate between all compositions that could be termed coppers or copper alloys, but, in conformance with general practice in the trade, includes those coppers and copper alloys commonly used in the manufacture of water service, distribution, and drainage pipe and tube.

1.4''This classification makes no attempt to differentiate between all applications of seamless copper and copper alloy piping and tube intended for use in water service distribution and drainage.

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 are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined.

1.6''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.
