ASTM A 109/A 109M Document Information:
Title
Standard Specification for Steel, Strip, Carbon (0.25 Maximum Percent), Cold-Rolled
ASTM International
Publication Date:
Oct 1, 2008
Scope:
This specification covers cold-rolled carbon steel strip in cut
lengths or coils, furnished to closer tolerances than coldrolled
carbon steel sheet, with specific temper, with specific edge or
specific finish, and in sizes as follows:
Cold-rolled strip is produced with a maximum specified carbon
not exceeding 0.25 percent.
Strip tolerance products may be available in widths wider than
2315/16 in. [600 mm] by agreement between
purchaser and supplier. However, such products are technically
classified as cold rolled sheet. The tolerances, finishes, tempers,
edges, and available widths and thicknesses differentiate cold
rolled strip from the product known as cold rolled sheet which is
defined by SpecificationA 568/A 568M and from cold rolled high
carbon strip which is defined by Specification A 682/A 682M.
For the purpose of determining conformance with this
specification, values shall be rounded to the nearest unit in the
right hand place of figures used in expressing the limiting values
in accordance with the rounding method of Practice E 29.
The SI portions of the tables contained herein list permissible
variations in dimensions and mass (see Note 1) in SI (metric)
units. The values listed are not exact conversions of the values
listed in the inch-pound tables, but instead are rounded or
rationalized values. Conformance to SI tolerances is mandatory when
the "M" specification is used.
NOTE 1—The term weight is used when inch-pound units
are the standard. However, under SI the preferred term is
mass.
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.
This specification is expressed in both inch-pound units and SI
units. However, unless the order specifies the applicable "M"
specification designation (SI units), the material shall be
furnished to inch-pound units.

standard.
