ANSI Z540.3 (ANSI/NCSL Z540.3), “Requirements for the Calibration of Measuring and Test Equipment,” has been reapproved. The document was reviewed and reaffirmed as is on March 26, 2013. This means that the technical content is still valid.
The new copy of ANSI Z540.3 has changes on 2 pages. The document number on the upper right hand corner of the cover is now ANSI/NCSL Z540.3-2006 (R2013). Then the inside front cover (page i) again has the new number in the upper right hand corner and the reaffirmation statement below the original approval date in the lower left hand corner.
Your only reason to purchase the document would be to assure your compliance auditors that your copy is indeed the latest edition. However, in practical terms, since there are no changes to the technical content there is no compelling rationale to buy this item. Our notifications to our customers on the reaffirmation date is on a FYI basis only.
The ANSI Z540.3 is the primary American National Standard on Calibration. It is often referenced at the same time as the ISO/IEC 17025 and ISO 10012 standards. It provides the user with the requirements for a calibration system that will ensure the accuracy of measuring and test equipment.
The standard has replaced a number of other documents. The document traces its roots back to the old MIL-STD-45662, “Calibration System Requirements.” The MIL Standard was originally replaced by ANSI Z540.1. Over time, NCSL determined that the ANSI Z540.3, released in 2006, would be the successor for the Z540.1. The two documents existed side-by-side for some time, until the Z540.1 was withdrawn in favor of the Z540.3 in 2008.
