EN ISO 1524:2020 - Fineness of Grind Testing for Paints and Inks
If you have been searching for to understand the specifics of the scratch test method, you have likely encountered technical jargon regarding "sclerometers" and "modulus of rupture." This article serves as a comprehensive breakdown of the standard. We will explore what ISO 1524 covers, why the "Hardness Pencil Test" is so widely used, and how to properly interpret the data found within the document.
If you are referencing the standard for a test procedure, the workflow defined in ISO 1524 generally follows these steps: iso 1524 pdf
Key topics and technical requirements * Scope and definitions: Defines fineness of grind and related terminology (see ISO 4618). * iTeh Standards
: It is applicable to all types of liquid paints and related products, except those containing very coarse particles (larger than the depth of the gauge). EN ISO 1524:2020 - Fineness of Grind Testing
Manufacturers use this test to determine the minimum required grinding time, preventing over-processing and saving energy.
ISO 1524 is the international standard used to determine the for paints, varnishes, and printing inks . The current version, ISO 1524:2020 , specifies a laboratory method to measure the particle size or presence of coarse particles in a liquid dispersion using a graduated gauge measured in micrometers (µm). Core Purpose and Scope * iTeh Standards : It is applicable to
The "fineness of grind" refers to the depth of the gauge at which discrete solid particles (like pigments) become visible in the liquid film. This is critical for quality control because particle size directly impacts: Affects gloss, color strength, and opacity.
