Superseeded by:

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.


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 E 29.

1.2 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are for information only.

1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use.
