ASTM B495-22

Standard Specification for Zirconium and Zirconium Alloy Ingots

ABSTRACT
This specification covers the six grades of zirconium and zirconium alloy ingots: Grade R60700, Grade R60702, Grade R60703, Grade R60704, Grade R60705, and Grade R60706. These materials shall be manufactured by electron beam, vacuum, or inert atmosphere melting in furnaces. The material shall form to the required chemical composition of zirconium, hafnium, iron, chromium, tin, hydrogen, nitrogen, carbon, niobium, and oxygen. Check analysis shall be performed. The following test methods shall be done: ultrasonic test and chemical test.
SCOPE
1.1 This specification covers six grades of zirconium ingots.  
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 The following precautionary caveat pertains only to the test method portion, Section 10, of this specification: 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 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.
