Plastics - Determination of melting behaviour (melting temperature or melting range) of semi-crystalline polymers by capillary tube and polarizing-microscope methods (ISO 3146:2022)
30-03-2022
This document specifies two methods for evaluating the melting behaviour of semi-crystalline polymers.a) Method A: Capillary tubeThis method is based on the changes in shape of the polymer. It is applicable to all semi-crystalline polymers and their compounds.NOTE1 Method A can also be useful for the evaluation of the softening of non-crystalline solids.b) MethodB: Polarizing microscopeThis method is based on changes in the optical properties of the polymer. It is applicable to polymers containing a birefringent crystalline phase. It might not be suitable for plastics compounds containing pigments and/or other additives which can interfere with the birefringence of the polymeric crystalline zone.NOTE2 Another method applicable to semi-crystalline polymers is described in ISO11357‑3.
