Vibration Laboratory has developed high accuracy capability to support national vibration and shock measurement activities. The chart illustrates the traceability for vibration measurement in Malaysia.

	The highest reference standard established is laboratory standard accelerometer B&K 8305 that is maintained using Laser Interferometry Calibration System. The frequency range is from 5 Hz to 10 kHz with the best uncertainty of 0.4%.

AC power and energy standard are maintained by Power/Energy Laboratory of NMIM. The function of the laboratory is to provide measurement and calibration of AC power and energy. In legal metrology, the laboratory involved in pattern approval of electricity meter used for trade.  

Photometry and Radiometry Laboratory has developed high accuracy system to support national illuminance scale. Illuminance scale is one of the fundamentals in the realisation of candela in optical radiation. The chart illustrates the traceability for illuminance parameter measurement in Malaysia. 

Measurement  range is start from 10 to 1000 lux with expanded uncertainty 1.1 %

Resistance laboratories provide the measurement traceability for resistance as well as development and maintenance of national physical standards for resistance. The laboratories provides calibration measurements with capability  from 1 mΩ to 1 TΩ. The National Standard of Resistance is a 1 Ω and 10 kΩ resistors kept in an oil bath at temperature of 23°C ± 0.001°C. The reference standard resistor is calibrated at BIPM on a regular schedule and disseminate to other resistors by using the automated DCC bridge at range of 1 mΩ to 10 MΩ. Resistance values below 1Ω achieved by using Direct Current Comparator Bridge with a Range Extender. The system has ratios up to 1000:1 with the relative uncertainty of 10-6. The resistance values from above 10 MΩ are scaled up using a modified Wheatstone bridge by replacing Resistive arms with 2 DC Voltage. The resistance laboratories dissemination, capability and uncertainty are shown in following table and diagram respectively.
