Paints and varnishes - Determination of hiding power - Part 3: Determination of hiding power of paints for masonry, concrete and interior use

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.

Paints and varnishes - Determination of hiding power - Part 3 : determination of contrast ratio of light-coloured paints at a fixed spreading rate

<p>ISO 6504-3:2006 describes methods for determining the opacity (by contrast ratio measurement) given by paint films of white or light colours of tristimulus value <i>Y</i> greater than 25, applied at a spreading rate of 20 m<sup>2</sup>/l to a black and white chart or to colourless transparent polyester foil. In the latter case, the tristimulus value <i>Y</i> is measured subsequently over black and white glass panels.</p>

ZOOM ON ... the Requirements department
To comply with a standard, you need to quickly understand its issues in order to determine its impact on your activity.

The Requirements department helps you quickly locate within the normative text:
- mandatory clauses to satisfy,
- non-essential but useful clauses to know, such as permissions and recommendations.

The identification of these types of clauses is based on the document “ISO / IEC Directives, Part 2 - Principles and rules of structure and drafting of ISO documents ”as well as on a constantly enriched list of verbal forms.
