标准范围
This part of ISO 11358 specifies general conditions for the analysis of polymers using thermogravimetrictechniques. It is applicable to liquids or solids. Solid materials may be in the form of pellets, granules orpowders. Fabricated shapes reduced to appropriate specimen size may also be analysed by this method.Thermogravimetry can be used to determine the temperature(s) and rate(s) of decomposition ofpolymers, and to measure at the same time the amounts of volatile matter, additives and/or fillers theycontain.The thermogravimetric measurements may be carried out in dynamic mode (mass change versustemperature or time under programmed conditions) or isothermal mode (mass change versus time atconstant temperature).Thermogravimetric measurements may also be carried out using different testing atmospheres, e.g. toseparate decomposition in an inert atmosphere from oxidative degradation.
