1.1?This specification covers the general requirements for hot-rolled, heavy-thickness sheet and strip in coils.

1.2?It applies to Specifications A414/A414M, A424/A424M, A1018/A1018M, and A1031/A1031M.

1.3?This material is available only in coils described as follows:

1.4?In case of any conflict in requirements, the requirements of the individual material specification shall prevail over those of this general specification.

1.5?For the purposes of determining conformance with this and the appropriate product specifications referenced in 1.2, measured values, calculated values, and observed 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 E29.

1.6?Annex A1 lists permissible variations in dimensions and mass (see Note 2) 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 Annex A1 is mandatory when the “M” specification is used.

1.7?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.

1.8?This specification and the applicable material specifications are 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.

1.9?This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
