The intention of these definitions and measuring practices is not to provide a dimensional specification for shape characteristics, but rather common procedure(s) for quantifying shape anomalies. Область применения

1.1 Shape is a significant quality characteristic for tin mill products. Plate-shape is affected by mill process factors plus the temper, thickness and width of the material supplied. It is the purpose of this practice to define accurately the different plate shape characteristics and to describe the practice(s) most commonly used to measure particular characteristics.

1.2 Quantitative limits are not addressed and should be established on an individual producer and user basis, where appropriate.

1.3 This standard does not purport to address 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 to determine the applicability of regulatory limitations prior to use.
