General information
60.60 Standard published Mar 31, 2022 ISO ISO/TC 61/SC 5 Physical-chemical properties International Standard 83.080.01 Plastics in general BuyingPublished ScopeThis document specifies general conditions for the analysis of polymers using thermogravimetric techniques. It is applicable to liquids or solids. Solid materials can be in the form of pellets, granules or powders. Fabricated shapes reduced to appropriate specimen size can also be analysed by this method. This document establishes methods for the investigation of physical effects and chemical reactions that are associated with changes of mass. This document can be used to determine the temperature(s) and rate(s) of decomposition of polymers, and to measure at the same time the amounts of volatile matter, additives and/or fillers they contain. This document is applicable to measurements in dynamic mode (mass change versus temperature or time under programmed temperature conditions) or isothermal mode (mass change versus time at constant temperature). This document is applicable to measurements at different testing atmospheres, such as separation of decomposition in an inert atmosphere from oxidative degradation.
