FORCE
The Laboratory for Force is responsible for the National Standards of Force providing the following additional services:
- Dissemination of the unit of force;
- Calibrations;
- Participation and coordination of international laboratory comparisons;
- Technical support for legal metrology.
Newton, symbol N, is the SI unit of force.
Defined as the amount of force required to give a one kilogram mass an acceleration of one meter per square second.
The traceability to the SI Unit of the Laboratory for Force is assured by the calibration of the standards.
The Laboratory for Force gets its traceability from PTB (Germany).
The Laboratory for Force of IPQ has the force National Standards.
The practical realisation of the unit of force makes use of known masses, which subjected to the effect of local gravitational force exert a known force on an earth located support.
The mechanical structure to handle and control such masses is known as a deadweight machine.
Force is therefore a derived quantity, with dimensions of length (L), mass (M), and time (T).
This can be illustrated from the fundamental equation:
force = mass × acceleration

International equivalence
Internationally recognized (peer-reviewed and approved) Calibration and Measurement Capabilities (CMCs) for calibration of force standards from 50 N up to 100 kN (compression and tension).
