This standard BS EN ISO 6504-3:2019 Paints and varnishes. Determination of hiding power is classified in these ICS categories:

• 87.040 Paints and varnishes

This document specifies methods for determining the hiding power given by paint coats of white or light colours of tristimulus values Y and Y₁₀ greater than 25, applied to a black and white chart, or to a colourless transparent foil. In the latter case the tristimulus values Y and Y₁₀ are measured over black and white panels. Subsequently, the hiding power is calculated from these tristimulus values.

This document also specifies a simple method for calculating the spreading rate for paints with a volatile matter content with low evaporation speed, e.g. coatings for interior walls and ceilings as specified in EN 13300.
