4  Specifications

Accuracy specifications presented herein are obtained by comparison with primary standards traceable 

to a national metrology institute or recognized international standard organization. These specifications 

are obtained in accordance with the ISO Guide to the Expression of Uncertainty in Measurement (GUM). 

The calibration program at Mensor is accredited by the American Association of Laboratory Accreditation 

(A2LA) as complying with both the ISO/IEC 17025:2005 and the ANSI/NCSL Z540-1-1994 standards. If 

there is an exception to the requirements and recommendations of Z540 during a calibration the excep-

tion is noted on the individual calibration certificate.
Mensor reserves the right to change specifications without notice.
