Fogging testing involves determining the fogging behavior of automotive interior materials. Volatile organic compounds (VOCs) from interior materials can deposit as a film on the windshield. The test quantifies this effect gravimetrically and\/or reflectometrically. <\/p>\n
A test specimen is heated in a fogging beaker at 100\u00b0C for 16 hours. The VOCs condense on a cooled surface (21\u00b0C). <\/p>\n
Evaluation:<\/strong> Heating temperature: 100\u00b0C \u00b1 0.5\u00b0C The following table shows all OEM-specific standards for fogging testing covered by the ASO laboratory:<\/p>\n The amount of volatile substances that outgas from interior materials when heated and deposit as condensation on glass surfaces. High fogging values = cloudy windshield = safety risk. <\/p>\n Gravimetric (mg) measures the condensate mass \u2013 the total amount of volatile substances. Reflectometric (%) measures the residual gloss of a glass plate \u2013 the optical impairment. Both are often determined in parallel. <\/p>\n The limit values are defined by the respective OEM in the specifications. Typical: gravimetric \u2264 2 mg, reflectometric \u2265 60% residual gloss. Stricter values often apply to components near the windshield. <\/p>\n The ASO laboratory performs fogging testing according to all common OEM standards. Our DAkkS accreditation according to DIN EN ISO\/IEC 17025 guarantees standard-compliant results. <\/p>\n Contact us<\/strong> for a quote \u2013 we will advise you on optimal sample planning and the scope of testing.<\/p>\n","protected":false},"excerpt":{"rendered":" Fogging Testing What is Fogging Testing?
