This standard specifies two methods for determining the content of moisture and other volatile substances in raw rubber: the hot mill method and the oven method-1. Its purpose is to accurately assess the purity and processing characteristics of raw rubber (primarily natural rubber and synthetic rubber polymerized from dienes)-1-4. The hot mill method involves heating and rolling the rubber using a specific open mill (hot mill) to drive off volatile components, while the oven method involves heating the sample in an electrically heated forced-air drying oven to a specified temperature-1-3. Both methods are based on the principle of weight loss upon heating, using an analytical balance with an accuracy of one ten-thousandth. It should be noted that the oven method (especially Procedure A) is the reference method for resolving disputes-1.
