(Specification)Standard Specification for General Requirements for Wrought Copper and Copper-Alloy Plate, Sheet, Strip, and Rolled Bar
Standard Specification for General Requirements for Wrought Copper and Copper-Alloy Plate, Sheet, Strip, and Rolled Bar
SCOPE
1.1 This specification covers a group of general requirements common to several wrought product specifications. Unless otherwise specified in the purchase order or in an individual specification, these general requirements shall apply to copper and copper-alloy plate, sheet, strip, and rolled bar supplied under each of the following product specifications issued by ASTM:B36/B36M, B96, B103/ B103M, B121/B121M, B122/B122M, B152, B169, B194, B291, B422, B465, B534, B591, B592, B694, B740, B747, and B768.
Note 1—A complete metric companion to Specification B248 has been developed—B248M; therefore no metric equivalents are presented in this specification.

3. Terminology
3.1 Definitions:
3.1.1 blank—apieceofflatproductintendedforsubsequentfabricationbyforming,bending,cupping,drawing,orhotpressing,
etc.
3.1.2 coil—a length of the product wound into a series of connected turns. The unqualified term “coil” as applied to “flat
product” usually refers to a coil in which the product is spirally wound, with the successive layers on top of one another.
(Sometimes called a “roll”.)
3.1.2.1 level or traverse wound—a coil in which the turns are positioned into layers parallel to the axis of the coil such that
successive turns in a given layer are next to one another.
3.1.2.2 level or traverse wound on a reel or spool—a coil in which the turns are positioned into layers on a reel or spool parallel
to the axis of the reel or spool such that successive turns in a given layer are next to one another.
3.1.3 lengths—straight pieces of the product.
3.1.3.1 ends—straight pieces, shorter than the nominal length, left over after cutting the product into mill lengths, stock lengths,
or specific lengths. They are subject to minimum length and maximum weight requirements.
3.1.3.2 mill—straight lengths, including ends, that can be conveniently manufactured in the mills. Full-length pieces are usually
8, 10, or 12 ft and subject to established length tolerances.
3.1.3.3 multiple—straight lengths of integral multiples of a base length, with suitable allowance for cutting if and as specified.
3.1.3.4 specific—straight lengths that are uniform in length, as specified, and subject to established length tolerances.
3.1.3.5 specific with ends—specific lengths, including ends.
3.1.3.6 stock—straight lengths that are mill cut and stored in advance of orders. They are usually 8, 10, or 12 ft and subject to
established length tolerances.
3.1.3.7 stock with ends—stock lengths, including ends.
3.1.4 plate—a wrought flat product over 0.188 in. thick and over 12 in. wide, in straight lengths or coils (rolls).
3.1.5 reel or spool—a cylindrical device that has a rim at each end and an axial hole for a shaft or spindle, and on which the
product is wound to facilitate handling and shipping.
3.1.6 rolled bar—arolledflatproductover0.188in.thickanduptoandincluding12in.wide,withsheared,sawed,ormachined
edges, in straight lengths or coils (rolls).
3.1.7 sheet
3.1.7 sheet—a rolled flat product up to and including 0.188 in. thick and over 24 in. wide, in straight lengths or coils (rolls).
3.1.8 strip—a rolled flat product, other than flat wire, up to and including 0.188 in. thick, in straight lengths, coils (rolls) or
traverse wound on reels or spools:

3.1.8.1 with slit, or sheared edges in widths up to 24 in. inclusive.
3.1.8.2 with finished drawn or rolled edges, in widths over 1 ⁄4 in. to 12 in. inclusive.
4. Materials and Manufacture
4.1 Materials—The material shall be of such quality and purity that the finished product shall have the properties and
characteristics prescribed in the applicable product specification listed in Section 1.
4.2 Manufacture—The material shall be produced by either hot- or cold-working operations. It shall be finished, unless
otherwise specified, by such hot working, cold working, annealing, or heat treatment as may be necessary to meet the properties
specified.
4.3 Edges—The edges shall be slit, sheared, sawed, or rolled edges, as specified. Slit edges shall be furnished unless otherwise
specified or agreed between purchaser and supplier or manufacturer. See 5.6 for edge descriptions and tolerances.
5. Dimensions, Weights, and Permissible Variations
5.1 General—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 may be cause for rejection.
NOTE 2—Blank spaces in the tolerance tables indicate either that the material is not available or that no tolerances have been established.
5.2 Thickness—The standard method of specifying thickness shall be in decimal fractions of an inch. For material 0.021 in. and
under in thickness, it is recommended that the nominal thicknesses be stated not closer than the nearest half-thousandth. (For
example, specify 0.006 or 0.0065 in., but not 0.0063 in.) For material over 0.021 in. in thickness, it is recommended that the
nominal thicknesses be stated not closer than the nearest thousandth. (For example, specify 0.128 or 0.129 in., but not 0.1285 in.)
A list of preferred thicknesses is shown in Appendix X1.X1. The thickness tolerances shall be those shown in Table 1, Table 2,
Tables 1, 2, and Table 3 for the product specification indicated:
