Scientific Metrology


Force Laboratory provides calibration and traceability of force transducers measurement in accordance to the BS EN ISO 376 and ASTM E74. Dead-weight force standard machine in the laboratory is maintained as force reference standard with capacity of 60 kN and two universal compression machines with capacity of 600 kN and 2000 kN. Several force transducers Class 00 with ranges of 50 kN, 100 kN, 250 kN, 600 kN, 1000 kN and 2000 kN are also available for calibration services.


Table below illustrates the capabilities and uncertainties obtained in force measurement at force laboratory:


Force Range


Elastic Force Measuring Instruments (Compression)0.5 kN to 60 kN0.004 %
Elastic Force Measuring Instruments (Compression)
Up to 100 kN 0.05 kN
100 kN to 270 kN0.4 kN

270 kN to 2000 kN

2.0 kN


Pressure Laboratory has developed a high accuracy measurement in order to support pressure measurement activities in the country. The laboratory is also responsible to ensure all of pressure measurement meet and comply with the global measurement standards.

Dead Weight Pressure Balance

At NMIM, Dead-weight Pressure Balances (DWPBs), are maintained as reference standards. There are also several sets of secondary and working standards such as Dead-weight Testers, Pressure Transducers and Water & Mercury Column Manometers being maintained in the laboratory.

The pneumatic pressure calibration capability is from x MPa up to 40 MPa while the hydraulic pressure calibration capability is from  y MPa up to 500 MPa.



Mass laboratory is responsible for the establishment and maintenance of Malaysia’s primary kilogram standard. The highest level of the structure is the national primary kilogram standards.


Hierarchical structure of mass standards is established to ensure the highest precision of mass standards with corresponding uncertainties, to provide various levels of weights ranging from standard weights with high accuracies to weights for commercial transaction.



The Mass Laboratory maintains weights of OIML Class E1 as reference standards and several sets of OIML Classes E2 to M1 as secondary and working standards in the range of 1 mg to 1 000 kg. 



National Metrology Institute of Malaysia (NMIM) is responsible for the maintenance and dissemination of the national standard for length measurement. NMIM is equipped with two set of iodine-stabilised He-Ne laser systems and on top of the hierarchy for traceability of length, dimensional, angle and form measurements. These laser systems are in accordance with recommendations set by the Consultative Committee for Length (CCL) of the Bureau International des Poids et Measures (BIPM). NMIM is capable to perform the calibration of many types of dimensional measuring instruments, gauges and components.
