This International Standard specifies two methods for evaluating the melting behaviour of semi-crystalline polymers.
Melting temperatures determined by the different methods usually differ by several kelvins for the reasons explained in the introduction.
Method A: Capillary tube
This method is based on the changes in shape of the polymer. It is applicable to all semi-crystalline polymers and their compounds.
Method B: Polarizing microscope
This method is based on changes in the optical properties of the polymer. It is applicable to polymers containing a birefringent crystalline phase. It may not be suitable for plastics compounds containing pigments and/or other additives which could interfere with the birefringence of the polymeric crystalline zone.
