FORCE AND TORQUE CALIBRATION

The Metal's Technological Center's Calibration Lab has the ENAC accreditation (138/LC10.098) in the torque area, for the calibration of dynamometric tools (dynamometric wrenches and screwdrivers), both in the lab and in the client's facilities.

Laboratory scope

In the torque area:

Calibration of 1 way (clockwise) torque tools from 1 Nm to 2000 Nm
(Check extent of the accreditation on www.enac.es)


In the force area:

Calibration in lab up to 50 kN and in the client's facilities, up to 10kN.

Equipments we calibrate

  • Torque wrenches in 1 direction (right-hand)
  • Torque screwdrivers
  • Dynamometers in 1 or 2 directions
  • Penetrometer

What is force?

We can understand force as the physical magnitude able to modify the quantity of movement or shape of materials. Its unit in the International Unit System is the Newton

Types of force

  • Traction: internal effort to which a body is submitted by the application of two forces that act in opposite ways.
  • Compression: internal effort to which a body is submitted by the application of two forces that act in the same way.

Force measuring equipment

  • Charge cells
  • Dynamometers

What does force calibration consist of?

Calibration consists of comparing the values indicated by the measuring instrument that is to be calibrated with the values of the pattern masses that are used in specific conditions and with a defined method, that takes into consideration the influence of the different factors that affect the reading of the equipment that is to be calibrated. The calibration is carried out in a controlled and documented way.


The calibration ensures the reliability of the measurements of the calibrated equipments and to warrant the adequate functioning in the facilities and processes where they are used, contributing to increase quality.


The result of the calibration is collected in a Calibration Certificate, where the correction values to be applied in different considered calibration points will be indicated, as well as the uncertainty of those measures.

What is torque?

The torque or tightening torque is a physical magnitude determined by the product of the tangential force by the distance between its point of application and a center of rotation. Its unit in the International System of Units is the Nm

Torque ways

Right-hand or dextrorotating: in the tightening direction

Left-hand or counterclockwise: in the opposite direction to the tightening direction
