Scope
This specification establishes the requirements for seamless copper tube intended for use in the connection, repairs, or alternations of air conditioning or refrigeration units in the field. NOTE 1—Fittings used for soldered or brazed connections in air conditioning and refrigeration systems are described in ASME Standard B16.22. NOTE 2—The assembly of copper tubular systems by soldering is described in Practice B 828. NOTE 3—Solders for joining copper tubular systems are described in Specification B 32. The requirements for acceptable fluxes for these systems are described in Specification B 813. The tube shall be produced from the following coppers, and the manufacturer has the option to supply any one of them, unless otherwise specified:

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. The following hazard statement pertains only to the test method described in Section 18.2.4 of this specification: 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 and health practices and determine the applicability of regulatory limitations prior to use.


Materials and Manufacture
Materials—The material of manufacture shall be billets, bars, or tube and shall be of such soundness as to be suitable for processing into the tubular products described. Manufacture: The tube shall be manufactured by such hot or cold working processes as to produce a homogeneous uniform wrought structure in the finished product. The tube shall be cold drawn to the finished size and wall thickness. Coiled lengths specified O60, soft annealed temper, shall be bright annealed after coiling, then dehydrated, and capped, plugged, crimped, or otherwise closed at both ends so as to maintain the internal cleanness of the tubing under normal conditions of handling and storage. Straight lengths specified H58 hard-drawn temper shall be cleaned and capped, plugged, or otherwise closed at both ends so as to maintain the internal cleanness of the tubing under normal conditions of handling and storage.






Chemical Composition
The chemical composition shall conform to the chemical requirements for the specific type of copper. These limits do not preclude the presence of other elements. When included in the contract or purchase order, and agreed upon by the manufacturer or supplier and the purchaser, limits shall be established and analysis required for unnamed elements.

Temper
Product under this specification shall be furnished in either O60 (soft annealed) or H58 (drawn general purpose) temper, as specified in the contract or purchase order and defined in Classification B 601. Coils are normally furnished in O60 temper and straight lengths in H58 temper.

Grain Size
Coiled lengths shall be furnished in the O60 temper and shall have a recrystallized grain size of 0.040 mm minimum when determined in accordance with Test Methods E 112.
Tensile Requirements
The tube shall conform to the tensile requirements prescribed.

^A ksi = 1000 psi. ^B See Appendix X1.

Nondestructive Testing
Electromagnetic (Eddy-Current) Examination: Each straight length of tube up to and including 31/s in. (79.4 mm) in outside diameter, shall be subjected to examination. Tubes that do not actuate the signaling device on the testing unit, after having been adjusted to provide information on the suitability of the tube for the intended application, shall conform to the requirements of this test. Testing shall be in accordance with Practice E 243. Testing of coiled lengths shall be subject to negotia-tion between the manufacturer and the purchaser. For tubes too large for the testing unit, the test method to be used shall be by agreement between the manufacturer and the purchaser.





Dimensions, Mass, and Permissible Variations
The standard dimensions and weights per foot for the various nominal sizes. Wall Thickness and Diameter—The tolerances for wall thickness and diameter shall conform to the requirements specified. Lengths and Tolerances: Standard Lengths and Tolerances—The standard length for coils shall be 50 ft (15.2 m). The length tolerances for 50-ft coils shall be +12 in. (305 mm) and -0 in. The standard length for straight lengths shall be 20 ft (6.1 m). The length tolerances for 20-ft lengths shall be +1 in. (25 mm) and -0 in. Tubes supplied in other than standard lengths and tolerances shall be in accordance with requirements established by agreement between the manufacturer or supplier and the purchaser. Roundness—For drawn unannealed tube in straight lengths, the roundness tolerance as specified. The deviation from roundness is measured as the difference be-tween major and minor diameters as determined at any one cross section of the tube. Roundness tolerance has not been established for annealed tube in straight lengths nor for tubes furnished in coils. Squareness of Cut—For tube in straight lengths, the departure from squareness of the end of any tube shall not exceed more than 0.010 in. (0.25 mm) for tube up to and including 5/s-in. (15.9-mm) standard size; and not more than 0.016 in./in. (0.016 mm/mm) of outside diameter, for tube larger than 5/s-in. standard size. For the purpose of determining conformance with the dimensional requirements prescribed in this specification, any measured value outside the specified limiting values for any dimension shall be subject to rejection.
