Need some non-chemical examples
eg Caesium standard for frequency, Atomic clock for time, and maybe Deadweight tester for calibrating pressure gauges ? - Rod57 (talk) 01:07, 27 August 2014 (UTC)

This page is really about a chemical standard, which even isn't necessarily a primary standard. The page should be retitled something like "Standard (chemistry)" and the existing title changed to link to the "Standards (metrology)" page, which duplicates the introductory information on this page and discusses Primary, Secondary, and Working standards in a more general context.
