SCOPE
This test method is intended to determine the thermal stability of a PVC compound when processed at a high temperature. The method is applicable to all PVC compounds, copolymers and products based on them.
PRINCIPLE
A test specimen of the PVC material is heated at a defined temperature, normally 180°C. The time taken for the material to degrade, indicated by evolution of hydrogen chloride is determined by a change of colour in a Congo Red test paper.
