Side curtain ventilation systems - Safety

1.1   General
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.

Introduction

In 2010, an accident occurred in both the Netherlands and Belgium where the child of a farmer was trapped

by an automatic stable display and later died.

The Dutch Technical Agreement (NTA) 8344 came about upon the initiative of the Labour Inspectorate in the

Netherlands, and this standard was created building on the work carried out by the NTA.

This standard is a type-C standard as specified in EN ISO 12100.

The machinery concerned and the extent to which hazards are covered are indicated in the scope of this

standard. These hazards are specified to the Side curtains ventilation systems.

Where provisions of this type C are different from those which are stated by type A or B standards, the

provisions of this type C standard take precedence over the provisions of th
...
