Description (English):

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.

Abstract

Overview

ISO 6504-3:2019 - Paints and varnishes: Determination of hiding power - Part 3 covers standardized laboratory methods to measure the hiding power (opacity) of white or light-coloured paints intended for masonry, concrete and interior use. The third edition (2019) defines procedures for measuring tristimulus values (Y and Y10 > 25) over black and white substrates or using a colourless transparent foil placed over black and white panels, and for calculating hiding power and spreading rate for interior coatings.

Key topics and technical requirements

Scope and materials: Applies to white or light-coloured paints for masonry, concrete and interior walls/ceilings; requires Y and Y10 > 25 for test specimens.
Measurement principle: Determination of tristimulus values (Y and Y10) over black and white panels and calculation of hiding power from these values. Spectrophotometric colour measurement is used for tristimulus values.
Substrate and methods: Three methods are specified:
- Method A: Coating on a transparent foil measured over black/white panels.
- Method B: Direct application to black and white charts.
- Method C: New (2019) method suitable for waterborne coatings; uses two coating thicknesses and interpolation/graphical determination.
Spreading rate: Procedures for calculating theoretical and practical spreading rates are included. The standard allows use of ISO 3233-3 calculation or a simplified method referenced in EN 13300 for low-evaporation interior coatings.
Supporting measurements: Density (ISO 2811), non-volatile matter content (ISO 3251) and sample preparation (ISO 1513 / ISO 15528) are referenced for auxiliary determinations.
Data handling: Includes calculation procedures, graphical interpolation between thicknesses, precision considerations and test-report requirements. Annex A provides interlaboratory comparison information.

Practical applications and users

Paint and coatings manufacturers: product development, formulation optimization and quality control of opacity/coverage.
Independent test laboratories and QC departments: standardized method for reproducible hiding-power measurements and reporting.
Specifiers, architects and contractors: verify product performance claims for interior masonry and concrete coatings.
Regulatory bodies and procurement: ensure compliance with performance standards and product classification (EN 13300).
