Notes:
Available methods for testing the transparency of plastic sheet and film have been found inadequate as regards the correlation between measurement and visual observation. A newly developed procedure, based on the determination of light transmission within a very small angle, gives good correlation. The application of the method and its limitations, due to the difference in optical effect of small-angle and large-angle scattering, are discussed. A description is given of the instrument, a special feature of which is that it gives direct readings of optical density and transparency.
