Caoutchouc brut — Détermination de la teneur en eau par la méthode de Karl Fischer

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.
