Mass Laboratory

• Maintain and assure the traceability of the National Measurement Standards of Mass
• Dissemination of the unit of mass by calibration of weights and mass standards in the range of 1mg to 2000kg.
• Calibration of a highly accurate and reliable equipments related to these national unit
• Conduct technical consultancy, training, and advice in Mass and Weight related fields
• Participate in national and international comparison measurement 

Mass pieces are calibrated using a variety of mass comparators. The laboratory is equipped with the both automated and manual electronic mass comparators with the capability of attaining the uncertainty requirements of OIML class E.
Computational software developed at KEBS enables accurate, traceable calibration of weights. The computations take into account important environmental influences, particularly air density. The most significant determinations are the estimates of variances and their propagation through the mass chain.
The laboratory has the capacity to check and ascertain the magnetic properties of mass standards through use of the susceptibility meter. The accuracy of mass measurement can be greatly affected by the magnetic susceptibility of weights. For high accuracy and conformance to a class (E1 to E2 and some ASTM classes), it is important to verify that magnetic susceptibility is sufficiently small.
Currently the laboratory is accredited by DKD of Germany to OIML class F1 based on ISO/IEC 17025 and is in the process of upgrading this accreditation to class E2 by the close of the year 2009. Visit www.dkd.eu laboratory number DKD-K-20001 for details.
