The D45 1010 standard, developed by the PSA Peugeot Citroen group, Europe's second largest automaker, describes a test method for determining color fastness to friction on all materials and all polymer parts inside and outside the passenger compartment. The basic principle of this test method is based on rubbing the samples to be tested with a colorless reference fabric that is dry or moistened with certain liquids. Color discharges on colorless reference fabrics and deterioration in the sample are evaluated using gray scales.
Gray scales are a scale used to evaluate deterioration in samples and discoloration in colorless reference fabrics. These scales are defined in the following two standards published by the International Standards Organization (ISO):
The color appearance of samples can be affected by the color of their environment and the color of any material used to mask them. Color fastness is the degree of resistance a color has on fabrics and leathers, which should allow the color to resist the pressures from its intended use. Grayscale allows evaluation of smearing and discoloration according to ISO 105 standards. This grayscale determines the color change of the sample in color fastness tests, such as perspiration fastness or washing fastness. The gray scale has 1 possible values from 5 to 9. 1 represents worst rating (significant variation), 5 represents best rating (no change).
In addition to the results obtained, the test report should include:
Among the numerous test, measurement, analysis and evaluation studies that our organization has given for businesses in various sectors, with its trained and expert staff and advanced technological equipment, the test to determine the color fastness of polymer materials and parts against friction within the scope of the D45 1010 standard, inside and outside the passenger compartment. also provides services.
