Standard Practice for Measuring Shape Characteristics of Tin Mill Products
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 The values stated in either in-pound or SI units are to be regarded as standard. Within the text, the SI units are shown in brackets. The values stated in each system must be used independently of the other. Combining values from the two systems may result in nonconformance with this specification.
1.4 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.
