Rims are a vital part of safety in cars. For this reason, manufacturers have been conducting a wide range of wheel tests and analyzes since the design studies of the products. These tests guarantee the quality and reliability of the company. Mechanical tests, metallurgical tests, color visuality tests, paint performance tests and dimensional measurements are performed for the wheels.
Mechanical tests are carried out on wheels to determine material fatigue and impact resistance to the intended vehicle. In this context, fatigue tests, impact tests, radial fatigue tests, dynamic fatigue tests and vertical deformation tests are applied.
Metallurgical tests are performed to determine the chemical composition and post-casting metallurgical properties of the aluminum alloy used in production. In this context, optical emission chemical composition analysis, microstructure analysis, macrostructure analysis, tensile tests, hardness tests and Charpy impact tests are applied.
Color visuality tests are performed to determine the color value and brightness level of the rim paint visually and with technical measurements. In this context, paint color measurements, paint brightness measurements and paint color visual controls are applied.
Paint performance tests are performed to determine whether the rim paint is resistant to road and seasonal conditions and whether it meets the quality requirements requested by customers. In this context, paint adhesion tests, paint thickness measurements, paint hardness measurements, stone impact resistance tests, low temperature resistance tests, air conditioning tests, steam spray tests and chemical resistance tests of paints are applied.
In dimensional measurements, the products are designed to determine whether they have dimensional measurements and surface sensitivity values. In this context, dimensional measurements and surface roughness measurements are applied.
The following are some of the standards that rim tests carried out by the competent authorities:
TS 8987 Road vehicles - Cars - Light alloy wheels
TS 11772 Road vehicles - Wheel balancing weights springs - For light alloy wheels and steel wheels
The application is received, the contract and then the product, vehicle and vehicles for which, what kind of service is determined exactly.
The necessary laboratory environment is prepared and the products, tools and instruments requested by the organization are tested by experts with the reference of the existing standards and measurements are made.
The data obtained as a result of meticulously completed tests, measurements and analyzes are evaluated and accredited approved reports are submitted by expert engineers.
