Terminology
Definitions:

For definitions of terms relating to copper and copper alloys, refer to Terminology B846.

Definitions of Terms Specific to This Standard:

capable of—the test need not be performed by the producer of the material. However, should subsequent testing by the purchaser establish that the material does not meet these requirements, the material shall be subject to rejection.

Ordering Information
Include the following information when placing orders for product under this specification:

ASTM Designation and year of approval (for example, ASTM B111/B111M – 04),

Copper or Copper Alloy UNS Designation (see Table 1),

Form (tube or ferrule stock),

Temper (see Temper section),

Dimensions, outside diameter, and wall thickness,

The following options are available and should be specified at the time of placing of the order when required:

Tension Test required per ASME Boiler and Pressure Vessel Code, Mechanical Properties section.

Pressure test as an alternative to eddy current test (Nondestructive Testing Section).

If the cut ends of the tubes do not need to be deburred (Workmanship, Finish, and Appearance section).

If the product is to be subsequently welded (Table 1, Footnotes G and H).

Residual Stress Test—Ammonia Vapor Test or Mer- curous Nitrate Test (Performance Requirements Section).

For Ammonia Vapor Test, risk level (pH value) if other than 10.

Heat identification or traceability details (Number of tests and Retests section).

Certification (Certification Section).

Mill Test Report (Mill Test Report Section).

If a subsequent thermal treatment after straightening is required (Temper section).

Materials and Manufacture
Materials—The material shall be of such quality and purity that the finished product shall have the properties and characteristics prescribed in this specification.

Manufacture—The product shall be produced by pro- cesses such as casting, extrusion, drawing, annealing, straightening, trimming, and other processes which may pro- duce a seamless tube in the specified condition.

Chemical Composition
The product shall conform to the chemical requirements specified in Table 1.

These composition limits do not preclude the presence of other elements. Limits for unnamed elements may be established by agreement between manufacturer or supplier and purchaser.

Copper Alloy UNS No. C19200—Copper may be taken as the difference between the sum of all the elements analyzed and 100 %. When all the elements in Table 1 are analyzed, their sum shall be 99.8 % minimum.

For copper alloys in which copper is specified as the remainder, copper may be taken as the difference between the sum of all the elements analyzed and 100 %.

When all the elements in Table 1 are analyzed, their sum shall be as shown in the following table:

whether minimum or nominal (Dimensions and Permissible Variations Section),

Quantity—total weight or total length or number of
