Belts used in mining industry need to be chosen very carefully, because of the flammability of the work environment and the required level of safety. It is critical to use the right product, specific for the application.
There is a number of test methods for measuring the performance of the flame resistant belts. Derby reserved special space in its plant for keeping fire test devices, in accordance with EN 12882 and EN 14973.
|Derby Covers||ISO Cover||ISO Safety Class*||Description|
|Flame Resistant||F||K / V / S||1||Above-Pit applications with risk only through electrostatic discharge|
|FR||K / V / S||2A / 2B||Above-Pit applications of abrasive material in potentially flammable atmosphere|
|FRF||K / V / S||3A / 3B||Above-Pit applications with additional risk of friction related flame|
|U-F||K / V / S||A||Undergorund applications with risk only through electrostatic discharge|
|U-FR||K / V / S||B1 / B2||Underground applications of potentially flammable atmosphere|
|U-FRF||K / V / S||C1||Underground applications with additional risk of friction related flame|
