A portion of 60 g of loose moulding material is dropped little by little into a measuring cylinder as evenly distributed as possible. A plunger with specified mass fitting to the measuring cylinder is slowly lowered until it is entirely supported by the material. After 1 min the volume of the material with the plunger resting upon it, shall be determined and the apparent density shall be calculated.

ISO 16620-4:2016 specifies a method of determining the biobased mass content in plastics products, based on the radiocarbon analysis and elemental analysis.


ISO 16620-4:2016 is applicable to plastic products and plastic materials, polymer resins, monomers or additives, which are made from biobased or fossil-based constituents.


This method is applicable, provided that the plastic product contains carbon element and that a statement giving its elemental composition and its biobased mass content is available.
