IS 101 : Part 1 : Sec 4 : 2024 Methods of Sampling and Test for Paints, Varnishes and Related Products - Part 1 Tests on Liquid Paints (General and Physical) - Section 4 Brushing Test
1 SCOPE
1.1 This standard prescribes procedures for assessing the brushing and flow characteristics of paints and related materials when applied to relatively large areas of closely defined substrates. It can also be used to observe other properties like the tendency of the paint to retract from sharp edges and protrusions with consequent loss of opacity and protective power.
1.2 This test does not allow the determination of paint properties in any absolute or precise sense because of the subjective factor involved in evaluating results. Nevertheless, when carried out by a skilled operator, and especially when used to compare the performance of a product under test of an agreed standard material, it has been found to give very useful information that is not attainable in any other way.
