Dans les secteurs de la fabrication, de la construction ou de l'automobile, l'utilisation de revêtements organiques exige une compréhension approfondie de leur résistance aux agressions chimiques, essentielle à la qualité et à la sécurité des produits. La norme ASTM D7835/D7835M-19 propose une méthode normalisée pour tester la résistance aux solvants à l'aide d'une machine de frottement mécanique simulant les conditions réelles d'exposition chimique. Cette méthode d'essai permet de déterminer…

When you need to test how well your organic coatings resist chemical damage, ASTM D5402-19R24 provides a standardized way to measure their durability. This test method uses controlled solvent rubbing to simulate real-world exposure conditions that your coatings might face in industrial or commercial environments. This standard helps you determine whether your paint, varnish, or…

ASTM D4752-20 provides a reliable method for testing whether zinc-rich primers are ready for the next coating layer. This standard uses a simple solvent rub technique to check how well ethyl silicate zinc-rich primers resist methyl ethyl ketone (MEK). The test helps you determine if your primer has cured enough before applying topcoats, preventing costly…

Metal powder manufacturing requires precise measurement of material properties to ensure quality and performance. ASTM B703-10 provides a standardized method for measuring apparent density of metal powders using the Arnold Meter, giving you reliable data about how much space your powder occupies under controlled conditions. This test method helps manufacturers understand powder flow characteristics and…

Powder metallurgy and metal injection molding industries rely on precise measurements of how metal powders flow to ensure quality products. ASTM B855-22 provides a standardized method for measuring volumetric flow rate of metal powders using specialized equipment called the Arnold Meter and Hall Funnel. This test helps you determine if your metal powders will flow…
