Full Description

This International Standard is one of a series of standards dealing with the sampling and testing of paints, varnishes, printing inks and related products.

It specifies a method for determining the fineness of grind of paints, inks and related products by use of a suitable gauge, graduated in micrometres.

It is applicable to all types of liquid paints and related products. Of the three gauges referred to in 4.1 the 100 m gauge is suitable for general use, but the 50 m and especially the 25 m gauge will only provide reliable results in the hands of skilled laboratory personnel. Particular caution is necessary in interpreting readings of less than 10 m.
