The paper presents a terse review on the evolution of measurement system and
International System of Units (SI) in India, the methodology followed to realize the …

A series of metal–carbon (M–C) eutectics with robust reproducible melting phase transitions
are evolving as the reference high-temperature fixed-points up to 3000° C for radiation …

Accurate and precise measurements of physico-mechanical quantities, such as Force,
Torque, Hardness, Pressure, Vacuum and Fluid Flow are extremely important and crucial in …

The traceable temperature measurements using the radiation thermometers and thermal
imagers above 1000° C require blackbody fixed points and extrapolation or interpolation of …

The novel materials of different phase transition temperatures are exploited in thermometry
as defined fixed points to form the International Temperature Scales (ITS). In the high …

This chapter describes the three physico-mechanical metrology streams; temperature and
humidity, optical radiation and acoustic and vibration metrology. Among the seven base SI …

In the efforts of redefining the SI units with fundamental constants of nature, kelvin (K), the SI
unit of thermodynamic temperatures (T), was redefined based on the Boltzmann constant (k) …

We report the results of a bilateral comparison of radiation temperature measurements
between SASO-NMCC (National Measurement and Calibration Center of Kingdom of Saudi …

The phase transition temperatures of MC eutectic binary alloy in the graphite crucible are
being used as high-temperature reference fixed points for both radiation and thermocouple …

Measurement standards play a pivotal role in the scientific and industrial development of a
