To request a quote for this test or others Scope: Fogging tests measure the tendency for plastic or elastomeric materials to volatize substances which can condense and collect on other surfaces when in use. These tests provide 2 methods for evaluating the likelihood of a material to leave a light scattering film on a glass surface (photometric method), or to deposit foreign material onto an aluminum foil surface (gravimetric method).

The tests are used to evaluate materials to be used in automotive or other vehicle interiors. Test Procedure: The test sample is placed in a sealed beaker - the inside surface of the cooled beaker cover is either glass (for the photometric method) or aluminum foil (for the gravimetric method). The bottom of the beaker is placed in a controlled temperature oil bath for a specified period of time - typically 3 hours for the photometric method and 16 hours for the gravimetric method. For the photometric method, gloss readings of the glass cover before the test and after conditioning following the test are compared. For the gravimetric method, weights of the test sample and the aluminum foil before the test and immediately after the test are compared.
