(Specification)Standard Specification for Refined Lead
Standard Specification for Refined Lead
ABSTRACT
This specification covers refined lead in pig, block, or hog forms. Lead shall be supplied in commercial standard forms or shapes requested by the purchaser in the following grades: low-bismuth low-silver pure lead, refined pure lead, pure lead, and chemical copper lead. All grades shall be manufactured by any smelting and refining process from ore or recycled materials to meet the specified chemical composition requirements. Chemical analysis samples shall be cleaned thoroughly to rid the surface of dirt or adhering foreign material either by sawing, drilling, or melting prior to sampling, and shall be selected either from the lot during casting, or from the final solidified cast product.
SCOPE
1.1 This specification covers refined lead in pig, block, or hog form.
1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
1.3 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 become familiar with all hazards including those identified in the appropriate Material Safety Data Sheet (MSDS) for this product/material as provided by the manufacturer, to establish appropriate safety and health practices, and determine the applicability of regulatory limitations prior to use.
