KS M ISO 248-2:2014 PDF

Scope: 1.1 This standard specifies the thermogravimetric method for measuring the moisture and other volatile content of raw rubber using an automatic analyzer with an infrared drying device. 1.2 This method applies to synthetic rubber (SBR, NBR, BR, It can be applied to measure the volatile matter content of IR, CR, IIR, halogenated IIR and EPDM) and to various types of raw rubber (lump, block, chip, pellet, grind, powder, sheet). This method can also be applied to other raw rubbers, but in this case, it is necessary to prove that the mass change is caused only by the loss of the original volatile content and not by rubber deterioration.1.3 This method is used for raw rubber that requires homogenization as specified in KS M ISO 1795. 1.4 The high-temperature mill method and oven method specified in KS M ISO 248-1 and the method specified in this standard do not provide the same results. Therefore, if a dispute arises, Procedure A among the oven methods specified in KS M ISO 248-1 must be used as the standard method.?
