Abstract / scope
This document specifies two test methods for the determination of water content of raw rubber and compounded rubber using a coulometric Karl Fischer titration method:
— method A uses an evaporator of heating tube type oven;
— method B uses an evaporator of vial type oven.
It applies to the water content range between 0,01 % and 1 %.
In case of dispute, method B is the preferred method.
