电子称重设备的校准

Calibration of electronic weighing equipment for accreditation purposes comprises the following instruments:

· Electronic, non-automatic scales with Max capacity up to 3000 kg;

· Electronic automatic scales with Max capacity up to 60 kg;

· Scales/electronic comparators with Max capacity up to 25 kg.

Standard calibration of non-automatic scales includes:

· estimation of errors of indication (systematic error) measured in maximally 5 testing points;

· estimation of repeatability parameter (random error expressed by standard deviation);

· estimation of errors being an effect of eccentric loading;

· estimation of errors of indication (systematic error) wherein the TARE device operates;

· issuing the Calibration Certificate.

Standard calibration of automatic scales includes:

· estimation of static errors (static error of indication, repeatability expressed as a standard deviation, errors being an effect of eccentric loading);

· estimation of dynamic errors (standard deviation estimated using tested sample);

· issuing the Calibration Certificate.

Assessment of conformity with requirements of the following documentation is possible:

· Directive 2014/31/EU of 23 February 2014 on non-automatic weighing instruments;

· Assessment of conformity with requirements specified by the client.
