ASTM A623M-02

Standard Specification for Tin Mill Products, General Requirements [Metric]

SCOPE
1.1 This specification covers a group of common requirements which, unless otherwise specified in the purchase order or in an individual specification, shall apply to tin mill products.
1.2 The following safety hazards caveat pertains to Annex A1 through Annex A8 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.
Note 1—This metric specification is equivalent to Specification A 623 and is compatible in technical content.

Tin Mill Products, General Requirements [Metric]
This standard is issued under the fixed designation A 623M; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A
superscript epsilon (e) indicates an editorial change since the last revision or reapproval.
This standard has been approved for use by agencies of the Department of Defense.
INTRODUCTION
This specification is the metric counterpart of Specification A 623. It is not intended to replace
A 623. Users of the standard should note several very significant differences in how the product is
produced and marketed.
(1) The metric product does not carry the overrun associated with tin mill products produced to
customary units. Metric tin mill products are produced to ordered size.
2
(2) The metric product is designated in units of 100 m called a SITA (System International Tinplate
Area), rather than in base boxes.
(3) The metric product is designated by thickness in millimetres rather than by basis weight.
(4) Coating weights are given in grams per square metre, not pounds per base box.
(5) Thickness tolerances are given in absolute figures instead of a 6 percentage.
(6) Each package of metric tin mill products contains 100 sheets, not the 112 of customary unit
packages.
All of the above significant differences, as well as others of lesser consequence, should be
considered when switching from Specification A 623 to A 623M.
