ISO 16862:2003 (R2022)

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.
