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 density of the specimen is calculated using the formula above. The result should be expressed in units of g/cm³ or kg/m³. din 53357 pdf
A very specific request!
DIN 53357 is a German standard for "Testing of plastics; determination of the density of plastics". Here's a draft paper based on the standard: The precision of the method is ± 0
