Significance and Use
3.1 This practice provides definitions and procedures commonly used for measuring flatness characteristics of steel sheet products under the jurisdiction of ASTM Committees A01 and A05 and their subcommittees as designated by a purchaser in a purchase order or contract.
3.2 Sheet flatness is affected by mill process factors plus the grade, thickness, and width of the material supplied. These measuring methods provide purchasers and suppliers with common definitions and procedures for flatness characteristics. The intention of these definitions and measuring methods is not to provide dimensional specifications for flatness characteristics, but rather common procedures for quantifying flatness anomalies. For determining compliance with flatness specifications, references are provided to appropriate ASTM standards.
3.3 This practice may be used by other ASTM Committees and other standards writing bodies for the purpose of measuring flatness characteristics of metal sheet products.
1.1 This practice covers definitions and procedures for measuring flatness characteristics of uncoated steel sheet and nonmetallic and metallic-coated steel sheet. The methods described are designed and intended to be used in mill situations and environments.
1.2 The sheet shall conform to all the requirements of the appropriate specifications as follows: Specifications or .
1.3 Quantitative limits are not addressed and are established in the general requirements, or individual product specifications, or both; or when applicable, as agreed to between supplier and user.
1.4 Units—The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined.
1.5 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.6 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.
