EUROLAB Laboratory provides accredited testing and conformity assessment services within the scope of FIAT 50451 standard. This standard specifies accelerated test procedures and equipment for determining the effects of sunlight on painted or colored interior trim materials during vehicle service.
FIAT 50451 Test Scope
The FIAT 50451 standard is used to conduct environmental tests in order to determine any deterioration in the appearance, physical properties and service properties of all kinds of painted surfaces. Test methods for accelerated aging in sunlight are classified according to the type of light source as Carbon arc type light exposure (FADE-OMETER) and Xenon arc type light exposure (XENOTEST).
FIAT 50451 Classification and Test Conditions
On the basis of test conditions, environmental tests are classified according to their severity, so it is ensured that effects of different intensity are simulated on the vehicle compared to those encountered during service.
Parameters are dependent only on test duration, such as severity for each test, temperature, relative humidity, light and light sources.
The test duration depends on the aging period to be simulated with a tolerance of ± 15 minutes or ± 1% according to the selected exposure time and is selected according to the following.
72 hours - Parts not directly exposed (e.g. ceiling tiles)
150 hours - Indirectly exposed parts (eg seat upholstery)
300 hours - Directly exposed parts (eg instrument panels)
Interpretation of FIAT 50451 Test Results
The tested material or tri is checked. Features must meet applicable requirements. Exposure times are determined for tests performed on different apparatus (Fade-Ometer or Xenotest) to produce the same degree or color loss. The sample is shown to the instrument to establish a precise correlation. After a certain loss of color is achieved, a second sample is exposed and remains in the apparatus until the same loss of color occurs.
The ratio of test times indicates the severity correlation of tests performed with the two apparatus. Generally, 1 hour of Fade-Ometer exposure corresponds to 1,3 hours of exposure in Xenot.
