scope:

NEN-EN-ISO 16927 specifies a method for testing the overcoatability and recoatability of unaged single-coat or multi-coat systems using a coating material which is intended for repairing damaged areas during or after installation. Since the testing of overcoatability and recoatability can be conducted under different conditions, this International Standard only specifies one procedure and indicates the basic parameters. The existing single-coat or multi-coat system is indicated as coating A and the new single-coat or multicoat system as coating B. The same applies analogously for the respective coating materials.
