Scope
This document describes the method of measuring the pH value of natural rubber and synthetic rubber using a pH meter equipped with a glass and silver composite reference electrode.
This document is applicable to natural rubber and synthetic rubber. It is also applicable to pre-vulcanized rubber and compounded rubber.
Note: When the pH value is greater than 11, the accuracy of the operation method described in this document will be reduced.
