This European Standard specifies the header frame dimensions of air filters for general ventilation to be used in air handling units, air intake system filters for rotary machinery and other applications. This includes pocket filters, rigid (V type) filters and filters to which header frame dimensions are applicable.

This document specifies requirements and gives reference to the test methods defined for fire dampers, which are intended to be installed in general Heating and Ventilating (HVAC) installations in buildings. All fire dampers close automatically in response to raised temperatures indicating fire. This document gives details for the provision of evaluation of conformity and marking of fire dampers. Fire dampers meeting the requirements of this document may be considered suitable for both ducted and non-ducted applications. This document applies to fire dampers with a declared specific fire resistance (Mandate M/117) that are to be used in conjunction with partitions to maintain fire compartments. This document is not applicable to fire dampers that may be used in applications where the presence of process chemicals may affect fire damper performances. This document is not applicable to non-mechanical fire barriers nor to air transfer grilles. To avoid duplication, reference is made to a variety of other standards. To this end, it is advised to read this document in conjunction with EN 1366-2 for details of the fire resistance testing and EN 13501-3 for classification.

The document specifies, dimensions, materials and performance requirements (including methods of test) for expansion groups, of nominal sizes from DN 15 to DN 25, having working pressures ) from 0,1 MPa (1 bar) to 1,0 MPa (10 bar). Expansion groups shall be fitted to the cold potable water supply only for expansion purposes, e.g. of storage water heaters, having a maximum distribution temperature of 95 °C. Expansion groups limit pressure in the water heater to which they are fitted, that is produced by thermal expansion of the water, prevent the backflow of water into the supply pipe and prevent the discharged water to get into contact with the water in the water heater. Expansion groups do not control temperature and alone do not constitute the protection required for storage water heaters. NOTE The use of the device specified in this Standard does not override the need to use controls (e.g. thermostats and thermal cut-outs) which act directly on the power sources of water heaters.
