Regulatory Compliance

Pipette Calibration by Zerosigma adheres to various international standards. National and International standards adhered to while carrying out performance verification and scheduled maintenance of pipettes.

ISO 3696 Water for analytical laboratory use Specification and test methods

ASTM E1154-14: 2014This specification covers requirements, operating conditions, and test methods for piston or plunger operated volumetric apparatus. (POVA)

ISO/IEC 17025: 2017-11: General requirements for the competence of testing and calibration laboratories (clause 7.8.4.1d, clauses 7.1.3, 7.2.1.4)

ISO/TR 20461: Determination of uncertainity for volume measurement made using the gravimetric .

Uncertainity is calculated using a coverage factor of k=2 (k=2 defines an interval having a level of confidence of approximately 95 percent) The uncertainity associated with the measurement is not included in determining inaccuracy Pass/Fail Results.
