IS 101 : Part 1 : Sec 4 : 1987 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

Prescribes procedures for assessing the brushing and flowcharacteristics of paints and related materials when applied torelatively large areas of closely defined substrates. It can alsobe used to observe other properties like the tendency of the paintto retract from sharp edges and protrusions with consequent loss ofopacity and protective power.

1.1 This test does not allow the determination of paintproperties in any absolute or precise sense because of thesubjective factor involved in evaluating results. Nevertheless whencarried out by a skilled operator, and especially when used tocompare the performance of a product under test of an agreedstandard material, it has been found to give very usefulinformation that is not attainable in any other way.
