[volt-nuts] Calibration and Certification - Trust and detail

[Marv @ Home]

Do you know what level of cal it was, if such exists in the UK? Or 
was it the now prescribed ISO 71205?  If 71025 that's fairly odd reporting.

In the USA, there are at least 3, ISO 9001, Z540 and 71025.  The 
first is the most common no-data cal, the last 2 should provide all 
required documentation as prescribed by the accreditor, only the last 
is internationally recognized.

Variation in "accredited" cal labs can exist if old standards are 
still allowed.
