Omfattning
1.1 This part of ISO 248 specifiestwo thermogravimetric methods for the determination of moisture and other volatile-matter content in raw rubbers by using an automatic analyser with an infrared drying unit.1.2 These methods are applicable to the determination of volatile-matter content in synthetic rubbers (SBR, NBR, BR, IR, CR, IIR, halogenated IIR and EPDM) listed in ISO 1629 and to various forms of raw rubber, such as bale, block, chip, pellet, crumb, powder and sheet. These methods might also be applicable to other raw rubbers, but in such cases it is necessary to prove that the change in mass is due solely to loss of original volatile matter and not to rubber degradation.1.3 The methods are not applicable to raw rubbers which need homogenizing as specified in IS 1795.1.4 The hot-mill method and the oven method specifiedin ISO 248-1 and the methods specifiedin this part of ISO 248 might not give identical results. In cases of dispute, therefore, the oven method, procedure A, specifiedin ISO 248-1:2011 shall be the referee method.NOTE These methods can be useful for routine determinations, e.g. quality control, when the measurement conditions for the automatic analyser are fxed for a particular raw rubber or grade of raw rubber.
