Quality test

Linearity and repeatability tests for load cells

The laboratory performs valid tests for quality controls for the purposes of the standard UNI EN ISO 9001, on load cells with capacities up to 500,000 kg (5,000 kN) in compression and up to 60,000 kg (600 kN) in tension.
The tests are performed at ambient temperature and, on request, for forces of up to 100 kN (10,000 kg), they can be carried out at temperatures of between -20°C and +200°C.

Unlike accredited calibrations, these tests do not officially guarantee that the measurements are referable to the national and international specimens and are not covered by the agreements of mutual international recognition. The tests are performed with weights and measures procedures inside the laboratory. Therefore, their results do not have the value of an officially recognized document. Quality tests can only be requested for LAUMAS products.

ATest di linearità

A test performed at 5 points of measurement that permits estimating the linearity error.

Available for the load cell only.

BTest di linearità e ripetibilità

Two consecutive tests performed at 5 points of measurement that permit estimating linearity and repeatability errors.

Available for load cells with or without a connected weight transmitter or indicator.
