Understanding DIN 53357: Adhesion Testing for Plastic Sheets
Principle: The principle of the method is based on Archimedes' principle, which states that the buoyancy force exerted on an object immersed in a fluid is equal to the weight of the fluid displaced by the object. By measuring the mass of the specimen in air and in a fluid of known density, the density of the specimen can be calculated. din 53357 pdf
