Grades of Conveyor Belting

Various national and international bodies have established rating systems for the belting used in general-purpose bulk-materials handling. Designed to provide a reference for end users as to what grades to use in different applications, the ratings specify different laboratory-test criteria without providing any guarantee of performance in specific application.

Belting grading variables help determine handling procedures.

In the United States, the Rubber Manufacturers Association (RMA) has established two standard grades of belting covers. RMA Grade 1 belting meets higher rubber tensile and elongation requirements, typically indicating improved cut and gouge resistance over the performance of Grade 2 covers. It should be noted that grade rating does not necessarily denote overall abrasion resistance. The International Organization for Standardization (ISO) has similarly established a grading system under ISO 10247. This standard includes Category H (Severe Cut and Gouge Service, Category D (Severe Abrasion Service, and Category L (Moderate Service). Category H is roughly comparable to RMA Grade 1; Categories D and L approximate RMA Grade 2 belting.

In addition, there are belting types manufactured to meet specific requirements of stressful applications, such as service with hot materials, in underground mines, or with exposure to oil or chemicals. As with most things, it is best to acquire an understanding of the operating conditions and then consult with reputable suppliers before selecting categories of belting.
