Annotation of standard text ASTM B306-20 :

This specification establishes the requirements for seamless copper tube (DWV) produced from Copper UNS No. C12200 and intended for sanitary drainage, waste, and vent piping. The tube shall be manufactured by such hot- or cold-working process as to produce a homogeneous uniform wrought structure in the finished product. The tube shall be cold drawn to the specified finished size, wall thickness, tensile strength, and Rockwell hardness. The tube shall be subjected to chemical analysis, Eddy-current test, and pneumatic test. Instead of sampling in accordance with Practice E 255, the manufacturer shall have the option of sampling at the time casting are poured or from the semifinished product, subject to the conditions set in the specification.

Additional information

Significance and Use

17.1 For the purpose of determining compliance with the specified limits for requirements of the properties listed in the following table and for dimensional tolerances, an observed value or a calculated value shall be rounded as indicated in accordance with the rounding method of Practice E29:

Property	Rounded Unit for Observed or Calculated Value

Chemical composition	nearest unit in the last right-hand place of
Hardness	figures of the specified limit

Tensile strength	nearest ksi (5 MPa)

1. Scope

1.1 This specification establishes the requirements for seamless copper tube (DWV) produced from Copper UNS No. C12200 and intended for sanitary drainage, waste, and vent piping.

Note 1: Fittings used for soldered or brazed connections in drainage, waste, or vent systems are described in ASME Standards B16.23 and B16.29 and CSA Standard B158.1.

Note 2: The assembly of copper drainage, waste, and vent systems by soldering is described in Practice B828.

Note 3: Solders for joining copper drainage, waste, or vent systems are described in Specification B32. The requirement for acceptable fluxes for these systems are described in Specification B813.

1.2 Units—The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.

1.3 The following hazard statement pertains only to the test method(s) described in this specification:

1.3.1 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.4 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.
