Page 2: Scope
Standard STD 420-0003 Volvo Group Version Page 1 Scope This standard specifies a test method which is intended to determine the fogging characteristics of materials that are used in the interior of motor vehicles. The method may also be applicable to fluid, pasty, powdered or solid raw materials which are the basis for such materials or from which the materials are manufactured. -
Page 3: Apparatus
Standard STD 420-0003 Volvo Group Version Page 4 Apparatus 4.1 General The equipment shall comply with the dimensional requirements specified in ISO 6452. Alternative equipments are permitted provided it has been ascertained that they give the same result as equipment complying with ISO 6452. -

Standard STD 420-0003 Volvo Group Version Page Dimensions in millimetres Ground Ø 90 ±1 Figure 1 Glass beaker 4.9 Aluminium foil discs for laboratory use; thickness 0,03 mm and a diameter of 102 ± 2 mm. The circular pieces of aluminium should be produced through stamping, and if so, for better results, the aluminium pieces should be stamped out of several layers of aluminium foil in order to decrease the risk of their edges being uneven and damaged. -

Standard STD 420-0003 Volvo Group Version Page Dimensions in millimetres Point of measuring Figure 2 Spacer on top of glass plate 4.12 Dishwasher, preferably connected to a deionized-water or distilled-water supply and possible to operate at 80 °C. An ordinary domestic dish-washer is not capable of washing at 80 °C and is normally not designed for alkaline dishwasher detergents. -
Page 6: Test Procedure
Standard STD 420-0003 Volvo Group Version Page 5 Test pieces Testing of components shall take place at the earliest one week after the date of manufacture and at the latest four weeks after the date of manufacture. Storage of components from the date of manufacture to the test date shall be identical to that of components supplied to production (same temperature, air humidity, wrapping, etc.). - Page 7 Standard STD 420-0003 Volvo Group Version Page Note: If the film of fluid contracts, this means that the tensile adhesion with the glass is less than the surface tension of the fluid. If it spreads, the tensile adhesion with the glass is greater than the surface tension of the fluid.
- Page 8 Standard STD 420-0003 Volvo Group Version Page 6.1.3 Control test with DIDP At least once a month, a control test shall be carried out in parallel, provided that DIDP is available for purchase from SP. The test is carried out by pouring 10 g ± 0,1 g of DIDP into the beaker in such a way that the DIDP does not make contact with the sides of the beaker (above the surface of the fluid).
- Page 9 Standard STD 420-0003 Volvo Group Version Page If the gloss readings, Fj, for the test pieces (glass plates) deviate by more than ± 5 % units from the mean value and none of the test pieces is approved, test a further two glass plates and calculate the mean value of the results obtained for all test pieces.
- Page 10 Standard STD 420-0003 Volvo Group Version Page Drying after fogging test After the fogging test, the aluminium foil shall be dried at 23 ± 1 °C with silica gel for 3 h and 45 min ± 15 min. When the silica gel has lost its blue colour, it shall be regenerated by driving out the water. The silica gel shall then be heated in an oven 175 ±...
