ASTM B440-12

Standard Specification for Cadmium

ABSTRACT
This specification covers refined cadmium metal in slab, ball or stick form. The cadmium shall be furnished in commercial standard forms or shapes. The cadmium supplied shall conform to the chemical requirements for one of the three grades, L01951, L01971, L01981. The producer may obtain representative samples from the molten metal during casting, and all or part of these samples may be cast into shapes suitable for chemical analysis. The material shall also conform to the chemical composition in iron, copper, nickel, lead, zinc, thallium, tin, silver, antimony, arsenic, and mercury.
SCOPE
1.1 This specification covers refined cadmium metal in slab, ball or stick form.
1.2 Toxicity—Warning: Soluble and respirable forms of cadmium may be harmful to human health and the environment in certain forms and concentrations. Therefore, ingestion and inhalation of cadmium should be controlled under the appropriate regulations of the U.S. Occupational Safety and Health Administration (OSHA). Cadmium-containing alloys and coatings should not be used on articles that will contact food or beverages, or for dental and other equipment that is normally inserted in the mouth. Similarly, if articles using cadmium-containing alloys or coatings are welded, soldered, brazed, ground, “flame-cut,” or otherwise heated during fabrication, adequate ventilation must be provided to maintain occupational cadmium exposure below the OSHA Permissible Exposure Level (PEL).
1.3 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.
1.4 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.
