6. Model Number Serial Number Voltage Complete description of the problem 2 Introduction Introduction The automotive industry has developed standard test methods for determining fogging characterstics which is the tendency of interior trim materials to pro duce a light scattering film or mass deposit on a glass surface Fogging is caused by the vaporization of volatile components from materials within the passenger compartment and the condensation of these volatiles on the cooler glass surface of the windscreen The various test methods written by the auto manufacturers SAE and ASTM require the use of a test chamber that simulates the conditions under which fogging takes place see Appendix A SAE Test Method The Hart Model 0011 is an approved instrument for simulating the environment where Fog occurs The basic requirements for a test chamber or apparatus include a heated cham ber or bath that controls the temperature of glass beakers at a set point between about 60 C and 120 C according to the test method procedure A glass test plate is placed on a silicone seal which rests over the opening of the beaker The glass plate must be cooled by the apparatus to a temperature set point be tween 20 and 40 The test method specifies the temperature set points to use see Appendix A SAE Test Method The user places a sample of the material being tested cut to 58mm at the bot tom of each glass beaker used for the test
