Standard Specification for Copper and Copper-Alloy Seamless Condenser Tubes and Ferrule Stock
 N B111/B111M

Annotation

This specification2 establishes the requirements for seamless tube and ferrule stock of copper and various copper alloys up to 31?8 in. [80 mm] inclusive, in diameter, for use in surface condensers, evaporators, and heat exchangers. The following coppers and copper alloys are specified:3 (Warning— Mercury is a definite health hazard in use and disposal.

Units—The values stated in either SI units or inchpound 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 nonconformance with the standard.

The following safety hazards caveat pertains only to the test methods portion, Section 19, 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.

2 For ASME Boiler and Pressure Vessel Code applications, see related Specification SB-111 in Section II of the Code.

3 The UNS system for copper and copper alloys (see Practice E527) is a simple expansion of the former standard designation system accomplished by the addition of a prefix "C" and a suffix "00." The suffix can be used to accommodate composition variations of the base alloy.

*A Summary of Changes section appears at the end of this standard.
