Physico Mechanical Standards
Physico-Mechanical Standards Division is one of seven R&D Divisions of National Physical Laboratory, India. The division constitutes of mechanical measurement activities involving the parameters of
1. Mass, Volume, Density and Viscosity Standards
2. Length and Dimension Standards
3. Temperature and Humidity Standards
4. Optical Radiation Standard (visible infrared and ultraviolet regions)
5. Force, Torque and Hardness Standards
6. Pressure and Vacuum Standards
7. Acoustic and Ultrasonic Standards
8. Fluid Flow Standards (Water medium only)
9. Shock and Vibration Sensors
The division is responsible to establish, maintain and continually upgrade the National Standards of Measurements related to above said activities and disseminates the standards by providing the apex level calibration services to the industry and institutions of the country and thus ensures the traceability to measurements made by these.
NPL, India is the signatory of the Mutual Recognition Arrangement (MRA) of BIPM and the calibration and measurement capabilities (CMC) of most of the activities are available on BIPM website (www.bipm.org).
The above activities participated in 07 international inter-comparison organized/ coordinated by BIPM and or APMP (Asia Pacific Metrology Program) / RMOs (Regional Metrology Organization of Asian region) regularly.
New measurement facilities were created to disseminate with improved measurement uncertainty to user industries by establishing the following primary/reference standards:
• One kg mass Comparator
• Traceability of the Flick Standard with Laser Interferometer
• Measurement of Type-S & R thermocouples to develop Standards thermocouples in the range
1000-1600 °C
• Variable Temperature blackbody primary standard of spectral radiance
• Vickers Hardness Primary Standard
• Fully automated fluid flow primary standard based on gravimetric method upto 60 K litre/hr.
In order to expedite the process of establishing the network of National Measurement System, the
scientists of this division helped National Accreditation Board for Testing and Calibration Laboratories (NABL)
as the Lead and Technical Assessors in assessing technical capabilities of several laboratories.
In order to maintain the uniformity in measurements capabilities of different industries operating in the
same area, well regulated proficiency testing program was organized in collaboration with NABL.
