Paints and varnishes - Evaluation of sag resistance (ISO 16862:2003)
ISO 16862:2003 describes test methods for evaluating the sag resistance (resistance to sagging) of paints, varnishes and similar coating materials (coatings) when applied to a substrate and held in a vertical position.Evaluation of the sag resistance can be carried out after the coating has been applied as follows:using a sag index applicator on a horizontally placed test panel which is afterwards put into a vertical position orusing a spray gun for application on a substrate in a vertical position.This International Standard is applicable to liquid coatings only.
