1 Scope
This part of GB 25115 covers, together with GB 25115-1 give the most significant hazards associated with air dryers, and in particular with tumble dryers having a net usable cage volume > 160L and tunnel finishers including associated conveyors and cabinet dryers.
This part complements the basic requirements as laid down in GB/T 15706.1 and GB/T 15706.2. It also gives guidance to the designer on assessing the risks associated with the hazards (see EN 1050) and on selecting measures for attaining the required safety level.
This part does not apply to ancillary equipment.
