scope:
This document specifies a laboratory test method for assessing microfoam in coating films on wood components. Samples are taken from finished wood components that are produced in a production plant, by craftsmen or a laboratory.
The test method can be used for further evaluation together with the performance specification given in EN 927-2. The amount and size of microfoam depends upon the coating material, the substrate and the application process and conditions.
