scope:

This document 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. This document discusses the safety aspects, performance and sustainability issues. Included are machines that operate using the potential energy stored by the earlier application of human or animal force, such as stretched springs. This document does not cover operation in environments where the electromagnetic disturbances are outside the range of those specified in EN 61000 6. 1.2 Exclusions This document does not apply to the following, which are intended for a different use: - doors and side curtains when used as doors which are specified in EN 13241 1:2003+A2:2016; - systems inflated by air; - screens supplied for the control of fire or smoke; - screens that move instantaneously upon the application of human force; - side curtains when used to control ventilation conditions in a toxic or explosive environments. This document does not cover the radio part of side curtain systems. If a radio operating device is used, the relevant ETSI standards are intended to be applied in addition.
