A very specific request!
The density of the specimen is calculated using the formula above. The result should be expressed in units of g/cm³ or kg/m³.
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.
This standard specifies a method for determining the density of plastics by measuring the mass of a specimen of known volume. The method is applicable to all types of plastics, including thermoplastics, thermosets, and elastomers.
The precision of the method is ± 0.1% for densities up to 1.5 g/cm³ and ± 0.2% for densities above 1.5 g/cm³.
The determination of density of plastics according to DIN 53357 is a straightforward method that provides accurate results. The method is widely used in the plastics industry to characterize the properties of plastic materials.
