Accredited Laboratory

TO PROVE LAB (MW Italia) is officially accredited according to the UNI CEI EN ISO/IEC 17025:2018 norm for the ECE R124 homologation of passenger car wheels and in accordance with the MQ17025 Quality Manual, latest release.

The accreditation was officialised by the technical committee of ACCREDIA, who issued the certificate LABORATORY N° 1533 on 11/5/23.

The accreditation guarantees:

  • the employment of qualified and expert personnel
  • the use of efficient and calibrated instrumentation
  • the use of suitable materials
  • the observance of environmental conditions suitable for the performed tests
  • the execution of a preliminary study of the method and its application through the evaluation and the validation measurement of uncertain results, if applicable
  • the impartiality of all laboratory personnel
  • the independence and absence of any conflict of interest.

Accredited tests

Rotating bending
Functional tests

A fatigue test with rotating bending moment that simulates the load condition to which the wheel is subject to when in use.

Rim-rolling test (wheel with tyre)
Functional tests

A fatigue test that allows to evaluate the wheel resistance during rolling under load, as on a road drive.

Impact test (wheel with tyre)
Functional tests

A resilience test to evaluate the resistance of alloy wheels subject to impact through a collision simulation.

Non-destructive tests (liquid penetrant inspection)
Functional tests

Non-destructive tests by means of liquid penetrant inspection to assess materials defects with no product damage.


Macroscopic analysis of welded joints of metallic materials
Materials analyses

The macroscopic analysis of welded joints on metallic materials allows to verify the shape and quality of the welds

Chemical Analysis - Optical Emission Spectroscopy (OES)
Materials analyses

The material to be analyzed is subjected to a powerful electrical discharge. Under the effect of this discharge, part of the surface vaporizes creating a cloud of excited ions that emit electromagnetic radiation.

Mechanical characteristics - Tensile test
Materials analyses

In a tensile test the specimen, usually a dog bone, is deformed by gradually increasing the axial load until failure.
