The extent of degraded plastic in computer equipment bodies is represented by the depth of the degradation from the surface. However, a Fourier transform infrared spectrometer can only measure the quantity of functional groups on the surface of the plastic. A relational equation between the depth of the degraded plastic and the groups on the surface was therefore devised, and the equation was experimentally shown to be valid. The degree of degradation was defined as the ratio of the quantity of decreasing C=C or C-H on the surface of a sample to that of C=C or C-H on the virgin plastic. It is thus concluded that this degree of degradation can be used to estimate the depth of the degraded plastic.
