ASTM B717-23

Standard Specification for Refined Ruthenium

ABSTRACT
This specification covers refined ruthenium as sponge and powder in one grade as follows: Grade 99.80 and Grade 99.90. The material may be produced by any refining process that yields a product capable of meeting the chemical requirements of this specification. The material should conform to the requirements for chemical composition as prescribed.
SCOPE
1.1 This specification covers refined ruthenium as sponge and powder in one grade as follows:  
1.1.1 Grade 99.80—Ruthenium having a purity of 99.80 %.  
1.1.2 Grade 99.90—Ruthenium having a purity of 99.90 %.  
Note 1: 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.

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.
