What is ISO 305- Determination of thermal stability of poly (vinyl chloride) about?
ISO 305 specifies two methods for the determination of the thermal stability of products and compounds based on vinyl chloride homopolymers and copolymers (referred to simply as PVC in the following text) by the extent of the discoloration that occurs when they are exposed, in the form of sheet, to elevated temperatures. The two methods are:
Method A: Oil-bath method
Method B: Oven method
