Why This Standard is Important

Viscosity is a critical parameter in the formulation and application of paints and varnishes. It affects the ease of application, the appearance of the final film, and the performance characteristics such as sag resistance and leveling. The BS EN ISO 2884-1:2024 standard provides a reliable method for measuring viscosity, ensuring consistency and quality in the production process.

By adhering to this standard, manufacturers can achieve a higher level of precision in their viscosity measurements, leading to improved product performance and customer satisfaction. This is particularly important in industries where the aesthetic and protective qualities of coatings are paramount, such as automotive, aerospace, and construction.

Technical Details

The standard specifies the use of rotational viscometers with a cone-plate measuring geometry. This setup is ideal for high shear rate measurements, which are necessary to simulate the conditions experienced by coatings during application. The cone-plate geometry provides a uniform shear field, allowing for accurate and repeatable viscosity measurements.

The document includes detailed instructions on the preparation of samples, the calibration of equipment, and the execution of the test procedure. It also provides guidance on the interpretation of results, helping users to make informed decisions based on their viscosity data.

This standard BS EN ISO 2884-1:2024 Paints and varnishes. Determination of viscosity using rotational viscometers is classified in these ICS categories:

• 87.040 Paints and varnishes

This document specifies the general procedure to be followed in determining the dynamic viscosity of unpigmented coating materials, such as paints, varnishes and related products, as well as binders at a shear rate range between 9 000 s?1 and 12 000 s?1. It describes an absolute viscosity measurement with cone-plate measuring geometry at high shear rates. The measured value gives information about the resistance offered by the material to brushing, spraying and roller coating during application. The method specified in this document is suitable for all paints and varnishes whether they are Newtonian in behaviour or not. For materials containing dispersions of large particles, the measuring geometry is expected to be adapted.
