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 Safety Data Sheet (SDS) for this product/material as provided by the manufacturer, to establish appropriate safety, health, and environmental practices, and determine the applicability of regulatory limitations prior to use.
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

Overview
ASTM B589-94(2021): Standard Specification for Refined Palladium sets forth the requirements for refined palladium available as sponge, cast bar, and wrought forms, specifying a single grade, Grade 99.95 (UNS PO3995). Developed by ASTM International, this specification guarantees a minimum palladium purity of 99.95% and establishes permissible levels for other elements including platinum group metals, gold, silver, and a variety of nonprecious metals. The document is designed for global acceptance, reflecting principles established by the World Trade Organization's TBT Committee, thereby supporting international trade and industrial application.
Key Topics
Forms and Purity Requirements
- Covers refined palladium as sponge, cast bar, and wrought forms.
- Specifies Grade 99.95 with a minimum of 99.95% palladium content.
- Controls for impurities such as platinum group metals, gold, silver, and non-precious elements.
- Allows for any refining process that achieves the required chemical composition.
Surface and Quality Standards
- Mandates that the surface quality of bars and wrought forms must be generally acceptable within the trade.
Sampling and Analysis
- Sampling methods and lot sizes are defined to ensure reliable chemical analysis.
- Chemical or spectrographic analysis methods for composition are by agreement between manufacturer and purchaser in the absence of standardized ASTM procedures.
- Reference to ASTM E29 for rounding analysis results.
Marking and Identification
- Requires each unit to be clearly marked or labeled with the palladium grade, lot or melt number, and precise weight.
Applications
The ASTM B589-94(2021) standard addresses the critical needs of industries that rely on high-purity palladium, ensuring consistent quality and traceability for a wide range of applications:
Electronics Manufacturing
- Used in the production of electrical contacts, connectors, and multilayer ceramic capacitors where high-purity palladium enhances performance and durability.
Catalysis and Chemical Processing
- Essential for manufacturing catalysts due to palladium’s remarkable catalytic properties and the need for ultra-pure material to prevent contamination.
Jewelry and Precious Metals
- Ensures that refined palladium used in jewelry and investment products meets stringent quality and purity expectations.
Medical Devices
- Provides assurance for use in dental alloys and other medical components where biocompatibility and high purity are paramount.
Research and Laboratory Use
- Supports development and validation of advanced materials and technologies requiring precise composition control.
