ISO 6452 specifies a test method that is intended to determine the fogging characteristics of rubber- or plastics-coated fabrics that are used as trim materials in the interior of motor vehicles.
ISO 6452 can also apply to fluid, pasty, powdered, or solid raw materials which are the basis for such trim materials or from which the materials are manufactured. The method can also apply to other materials and finished products.
The procedure is applicable to the measurement of fog condensate on glass surfaces within the limits of the test conditions. This test cannot measure accurately those cases in which:
ISO 6452 on the trim materials in the interior of automobiles is relevant to:
Automotive interior components may contain semi-volatile constituents which could evaporate into the atmosphere within the vehicle’s cabin leading to fogging of a vehicle’s windscreen.
ISO 6452 provides the required guidelines on conduction a test method that is intended to determine the fogging characteristics in automobiles, including apparatus, conditions, test pieces, procedures, and expression of results.
Compliance with standardised tests under ISO 6452 helps prevent fogging in automobiles, which is an important factor influencing visibility while driving. Trim materials that comply with these standardised tests will be able to impart a higher degree of safety of the product end-user by minimizing the incidence of accidents.
