Popis:	The temperature rise that occurs on shearing rubber at high rates in the shearing-cone plastometer has been measured and shown to be about double that which is to be expected from simple theoretical considerations. This discrepancy is apparently due to heating of the rotor. The temperature rise in normal Mooney plastometer tests may be great enough to influence significantly the results, particularly during scorch tests, but relative results on stocks of not very different plasticities (as in control tests of a given mix) would not be appreciably affected.
