JIS K 6218-1:2005 (R2014)

This part of JIS K 6218 specifies a method for determining the loss on heating of carbon black for use in the rubber industry. This loss on heating is due primarily to loss of moisture, but traces of other volatile materials may also be lost. This method is not applicable to treated carbon blacks which contain added volatile materials. There are the following three kinds of method for the determination of loss on heating. Method A is the method to be standard, however, if the same results can be obtained, method B or method C may be used. -Method A the method using an oven -Method B the method using a moisture balance -Method C the method using an infrared moisture meter (rapid method)
