(Specification)Standard Specification for Refined Palladium
Standard Specification for Refined Palladium
ABSTRACT
This specification covers refined palladium as sponge, cast bar, and wrought forms in one grade designated as Grade 99.95 (UNS PO3995). The metal may be produced by any refining process that yields a product capable of meeting the chemical composition requirements prescribed for palladium, platinum group metals other than palladium, gold, silver, lead, tin, zinc, iron, copper, silicon, magnesium, calcium, aluminum, nickel, chromium, cobalt, manganese, and antimony. The surfaces of bars and wrought forms shall exhibit quality generally acceptable to the trade. Sampling requirements for chemical analysis including lot size are given.
SCOPE
1.1 This specification covers refined palladium as sponge, cast bar, and wrought forms (Note 1) in one grade as follows:
1.1.1 Grade 99.95 (UNS PO3995)—Palladium having a purity of 99.95 %.Note 1—Other forms of unfabricated palladium of commerce are not to be excluded under this specification.Note 2—For the purposes of determining conformance with this specification, an observed value obtained from analysis shall be rounded to the nearest unit in the last right hand place of figures used in expressing the limiting value, in accordance with the rounding method of Practice E29.
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.
