DIN 53375 is a German standard that measures how slippery or grippy plastic films and sheets are when they slide against each other. This test determines both static and kinetic coefficient of friction (COF) values, which tell you how much force is needed to start sliding two surfaces and keep them sliding. Understanding these friction…

When you need to test how well rubber and elastomer materials resist wear, DIN 53516 provides the foundation for reliable testing methods. This German standard was created to measure abrasion resistance in rubber products before becoming the basis for the widely-used ISO 4649 standard. Understanding this test helps you evaluate material durability and performance in…

Coil coated metals face constant exposure to cleaning agents, industrial solvents, and chemical substances throughout their service life. EN 13523-11 provides a standardized method to test how well these protective coatings resist damage when rubbed with common solvents. This European test standard helps manufacturers and specifiers determine whether a coated metal product can withstand real-world…

DIN ISO 3923‑2:1987 provides a standardized method for measuring the apparent density of metallic powders using the Scott Volumeter technique. This test standard helps you determine how much space metallic powder occupies under controlled conditions. The Scott Volumeter method gives you consistent and repeatable measurements of powder density, which directly affects how materials flow, pack,…

DIN 66137-3 is a testing standard that helps scientists and engineers measure how dense particles are using gas pycnometry. This method works by measuring how much gas is displaced by a sample, giving accurate results for materials like powders, granules, and porous solids. The gas buoyancy method is particularly valuable when working with materials that…

When it comes to handling solid fertilizers, understanding how they flow and stack is crucial for farmers, manufacturers, and engineers. DIN EN 12047 is a European standard test method that measures the static angle of repose for solid fertilizers. This measurement helps determine how easily fertilizer will flow through machinery, how it will stack during…
