Scope*1.1 This specification covers two types of commercial rolledzinc as describ

3、ed in 1.2. It should be understood that thespecification is general. Any closer limitations on permissiblevariations shall be a matter of agreement between the supplier(manufacturer) and the purchaser.1.2 Rolled zinc is furnished in two types as follows:1.2.1 Type I - Coils or sheets cut from strip

4、(ribbon) rolledzinc and1.2.2 Type II - Zinc plates such as boiler and hull platesproduced by any rolling method.1.3 The values stated in inch-pound units are to be regardedas the standard. The values given in parentheses are forinformation only.1.4 This standard does not purport to address all of th

5、esafety concerns, if any, associated with its use. It is theresponsibility of the user of this standard to become familiarwith all hazards including those identified in the appropriateMaterial Safety Data Sheet (MSDS) for this product/materialas provided by the manufacturer, to establish appropriate
