Fogging tests

These tests consist of condensation of evaporated, volatile components from interior equipment on vehicular window glass, the front windscreen in particular. Determination of the fogging characteristics (liquid raw materials, paste and solid raw materials contained in the materials from which they are made) can be conducted using the following methods:
  • fogging value - quotient of reflectometer 60° value of glass plate with fogging precipitate and reflectometer 60° value of the same glass plate without fogging precipitate
  • fogging value - quotient of transmittance of glass plate with fogging precipitate and transmittance of the same glass plate without fogging precipitate
  • components condensation (G) - difference of the weight of aluminium foil with and without fogging precipitate
