GB/T 9272-2007 "Paints and varnishes - Determination of the volume fraction of non-volatile matter by measuring the density of a dried coating" specifies the method for calculating the volume fraction of non-volatile matter based on the density of the dried coating, and it is applicable to paints and varnish products. The method involves measuring the density of the dried paint film and converting it to the volume fraction in combination with the mass fraction of non-volatile matter. The testing requires instruments such as a density measuring device, analytical balance, constant temperature drying oven, and paint film applicator, providing essential parameters for controlling coating film thickness during application and for formulation design.
