Metrology Department

OVERVIEW

The Kenya Bureau of Standards Metrology laboratories became a full member of the General Conference of Weights and Measures (CGPM) of the Metre Convention and a signatory of the Committee of Weights and Measures Mutual Recognition Arrangement (CIPM-MRA) since Jan 2010.
The Metre Convention created the Intrernational Bureau of Weights and Measures (BIPM) and set the framework for global collaboration in the science of measurement including its industrial, commercial and societal application.
The original aim of the Meter Convenction in 1875 was the worldwide uniformity of measurements which remains as important today.

Services  offered
Metrology department is mandated to realise, maintain and disseminate the SI units of measurements. In fulfilling this mandate the department currently operates 13 primary laboratories as follows.
  • Mechanical Metrology
    Laboratories
  • Electrical Metrology
    Laboratories
  • Mechanical  workshop
    and Instrumentation
  • Metrology Liaison
    and QMS
  • Mass
  • Pressure
  • Temperature
  • Density  and Viscosity
  • Force
  • Volume and Flow
  • Dimensional Metrolog
The following are caliberated by the electrical metrology laboratory
  • Time and Frequency
  • AC/DC (Direct Current and Low Frequency measurements)
  • Energy and Transformer
  • Photometry
  • Acoustics and Vibration
  • Dosimetry (Ionising radiation)
These two units support the primary laboratories and the testing laboratories. They have sufficient equipment and personell to offer the  support required for most of the repairs normally required.

The metrology sales, marketing(Liaison) and QMS is a function that facilitates the smooth running of the primary laboratories in carrying out their mandate, that is ensuring traceability of measurements to International Standards, custody and maintenance of National measurement standards and dissemination (calibration) of  the SI units of measurement. The function is the face of Metrology and the link to the customers.

The function oversees the implementation, maintenance and improvement of the quality management system which is according to ISO/IEC 17025-General requirements for the competence of testing and calibration laboratories. The head of this function is also the Metrology Quality Manager.

The quality manager evaluates and puts measures in place that enable improvement of the quality system on a continuous basis. This includes planning and conducting quality audits and management review meetings.

All documentation pertaining to the QMS are prepared, maintained and updated regularly.

Relevant Laboratory Information Management Systems (LIMS) are utilized.

All equipment to the primary laboratories from the customers are handled/ processed by this function. The customer equipment at the regions is handled by the metrology representatives there on behalf of this function.

All quotations, tenders, orders, invoicing, payments and reconciliation for calibration work are handled by or through this function.

Most metrology customer enquiries and complaints are also handled and resolved by this function. Other programmes/ projects are also undertaken by this function on behalf of the department e.g. customer care, automation of systems and consultancy/ training curriculums e.t.c.

The head of this function with assistance of several officers at the headquarters and in the regions does most of the marketing and customer feedback both positive and negative as required by ISO/IEC 17025 and ISO 9001.

The technical officers in this function also give relevant information and advice to our customers and stakeholders.
