scope:

This European Standard specifies the standardization of side curtain ventilation systems supplied for environmental control, installed on farm buildings, that use a barrier made from a flexible foil or fabric which moves via a rolling or folding action, or rigid panels that slide, as far as safety aspects, performance and sustainability issues are concerned. Included are machines that operate using the potential energy stored by the earlier application of human or animal force, such as stretched springs. This European Standard does not cover operation in environments where the electromagnetic disturbances are outside the range of those specified in EN 61000-6-3.
