ISO 16862:2003 PDF

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:

1. using a sag index applicator on a horizontally placed test panel which is afterwards put into a vertical position or
2. using a spray gun for application on a substrate in a vertical position.

This International Standard is applicable to liquid coatings only.
