NF T 30-046

Introducing NF T 30-046 – Industrial Physics

NF T 30-046 is a national French testing standard that was developed to determine the fineness of grind properties of paints using a grindometer.  

The Norme Française (NF) testing standards are guidelines and requirements developed by AFNOR (Association Française de Normalisation), which is the French standardization organization. The NF testing standards are designed to ensure the quality, safety, and performance of materials and products in many different industries. 

Why is fineness of grind testing important?

Fineness of grind testing is essential for paint manufacturers. It’s also relied upon by many end users who inspect the content of their paints during their own production process. It’s a simple yet effective way to measure the uniformity of the pigment particles they contain using a grindometer. 

Typically, your paints will need to be ground or milled into fine particles before they are mixed into a liquid form for dispersion. This is why fineness of grind testing is important. It helps you to evaluate the physical properties of the paint particles and the point at which their size exceeds the thickness of the film itself when painted, spread, or sprayed.

So, how can Industrial Physics improve your NF T 30-046 fineness of grind testing?

TQC Sheen Automated Fineness Of Grind Gauge Scanner
TQC Grindometers are suitable for use with the state-of-the-art TIDAS system. This automated fineness of grind gauge scanner is supplied by Labman 

The system rates the particle dispersion in materials such as paints, lacquers or pigments. It differentiates between air bubbles and true particles and the rating can be customized to the requirements of each customer.  

TQC Sheen Grindometers
Our grindometers and fineness of grind gauges are precision instruments to determine particle size and fineness of many materials like paints, pigments, and filler. Most TQC Sheen Grindometers have double grooves with graded slopes graduated in three different parameters: µm (microns), NS (Hegman) and PCU (North).
