Understanding the Oil Immersion Fog Test 880504

In 1985, a draft standard procedure was issued by the International Standards Organization (ISO/DIS 6452) for evaluating the fogging propensity of automotive interior trim materials using an oil immersion test apparatus. Our evaluation indicates that this procedure fails to take into account a number of variables, the control of which are crucial to the attainment of rational test data. Results of experiments conducted to investigate the effects of these variables are presented and, based on our findings, an improved method for measuring and specifying the fogging behavior of interior trim materials is proposed.
