This standard is one of a series of standards on sampling and testing of paints, varnishes, printing inks and related products. This standard specifies the method for determining the fineness of grinding of paints, varnishes and printing inks using a suitable fineness gauge (scaled in microns). This standard applies to all types of liquid paints and varnishes and related products. Among them, the fineness plate of 100 μm is suitable for general occasions, but the fineness plate of 50 μm, especially the fineness plate of 25 μm can only be obtained by skilled laboratory personnel to obtain reliable results. Special caution should be exercised when judging readings smaller than 10 µm.
