Deals with the sampling and testing of paints, varnishes and related products. Specifies a method to determine the density of paints, varnishes and related products using an oscillator. Suitable for all materials, including paste-like coatings. The method also applies to aerosols if a pressure-resistant type of apparatus is used.
