Significance and Use

For purpose of determining compliance with the specified limits for requirements of the properties listed in the following table, an observed value or a calculated value shall be rounded as indicated in accordance with the rounding method of Practice E 29.

Property	Rounded Unit for Observed or Calculated Value

Chemical composition	nearest unit in the last
	right-hand place of figures
Tensile strength	nearest ksi [nearest 5 MPa]
Elongation	nearest 1 %
Expansion	nearest 1 %
Grain size	nearest multiple of 0.005 mm

1. Scope

1.1 This specification establishes the requirements for condenser, evaporator, and heat exchanger U-bend tubes that are manufactured from seamless copper and copper alloy tube.

1.2 The following safety hazard caveat pertains only to the test methods described in this specification.

1.2.1 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 and health practices and to determine the applicability of regulatory limitations prior to use.

1.3 Units—The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.

1.4 This specification is applicable to product 2 in. [50 mm] or less, inclusive, in diameter.

1.5 The product shall be produced from one of the following coppers or copper alloys, as specified in the ordering information:
