Scope

1.1 This part of GB/T 24131.1 specifies two methods for determining the volatile
matter content of raw rubber by hot-mill method and oven method.
1.2 These methods are suitable for determining the volatile matter content of
the group-R rubbers as listed in GB/T 5576. The group-R rubber refers to a
rubber containing an unsaturated carbon chain, such as natural rubber and a
rubber which is at least partially synthesized from a diolefin. These methods are
also applicable to the determination of other rubbers, but in this case, it must
be verified that the change in mass is due only to the loss of actual volatile
matter rather than rubber degradation.
1.3 The hot-mill method is neither suitable for natural rubber and synthetic
rubber that is difficult to handle on hot-mills, nor suitable for chip and powdered
rubber.
1.4 Determination by these methods may not give the same result. Therefore,
in the case of controversy, oven method A is a reference method.
Note. Refer to Appendix A for the test methods applicable to different types of
rubber.
