ASTM WK39101

(What is a Work Item? / How to Input to a Work Item)

Work Item: ASTM WK39101 - Revision of B521 - 98(2004) Standard Specification for Tantalum and Tantalum Alloy Seamless and Welded Tubes


Active Standard: B521 - 12

Developed by Subcommittee: B10.03 | Committee B10 Home | Contact Staff Manager



1. Rationale

This standard is being revised to address a negative vote that resulted from a ballot in August 20111 to re approve the standard. The negative vote, which was found to be persuasive at the fall 2011 committee meeting, requested that the certification section of the standard be revised to make certification mandatory rather than when requested by purchase order. This change will make the standard more consistent with the certification requirements of other standards thin B10 and general industry practice.
