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 parameters and recommendations presented in this standard relate mainly to the material polyamide 12 (PA12). Explicit references are also made to polyamide 11 (PA11). The extent to which these parameters and recommendations can be transferred to other materials must be verified on a case-by-case basis.

This standard is aimed at providers of manufacturing services for polymer parts who use additive manufacturing machines and at the customers for these services. Designers of parts as well as buyers and providers of manufacturing services can specify, in a traceable manner, the required or the achievable level of quality with the aid of this standard. This standard applies to parts that have been manufactured from a thermoplastic polymer by means of laser sintering (LS) or material extrusion (MEX). Its applicability to other processes for polymers shall be checked in the specific case. The quality grades apply to parts that have not been post-processed after unpacking from the build space and the removal of possible support structures.

This document specifies the requirements for determining the maximum propulsion power rating using manoeuvring speed for engine-driven craft with a length of the hull (LH, as defined in ISO 8666) between 8 m and 24 m.This document is applicable to craft with a calculated Froude number (Fn) = 1,1.This document is not applicable to:— inflatable craft, as defined by ISO 6185-4;— craft designed and constructed solely for competitive racing (racing craft);— craft primarily designed not to be engine driven.This document does not specify craft constructional strength requirements related to maximum propulsion power rating and does not guarantee stability under all conditions of seaway, wind, wakes and waves.

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.

This document specifies the composition, property requirements including electrical properties, and tolerances on dimensions and form for seamless drawn copper tubes for electrical purposes, delivered in straight lengths or alternatively in level wound coils with the cross-sections and size ranges below:- for round tubes in straight lengths with outside diameters from 3 mm up to and including 450 mm and wall thicknesses from 0,3 mm up to and including 10 mm;- for round tubes in level wound coils with outside diameters from 3 mm up to and including 30 mm and wall thicknesses from 0,3 mm up to and including 10 mm;- for square and rectangular tubes with major outside dimension from 5 mm up to and including 150 mm and wall thicknesses from 0,5 mm up to and including 10 mm.The sampling procedures and test methods for verification of conformity to the requirements of this document are also specified.

This European Standard applies to hydronic fan coil units (FCU) as factory-made single assemblies which provide the functions of cooling and/or heating but do not include the source of cooling or heating.The standard covers both air free delivery and air ducted units with a maximum external static pressure due to duct resistance of 120 Pa max.The standard applies to all types of fan speed control of a fan coil unit (variable speed, multispeed).This standard deals with the cooling and heating functions of the FCU considered as an emitter for cooling/heating of a room/space. It does not cover any ventilation function of the unit.If the FCU can also provide fresh air, this function is not considered and the fresh air inlet closed during testing.This European Standard provides a method for the determination of the thermal performance of fan coil units in standard conditions, for the use with hot or chilled water or water mixtures. The test procedures given in this standard may additionally be used for determining performance at other conditions.It also provides the method for the determination of the air flow rate supplied by the fan coil unit.The standard does not cover the rating of heating or cooling from direct expansion coils or heating from electric resistance elements.The standard does not cover acoustic performance of fan coil units which is dealt with in EN 16583.It is not the purpose of this standard to specify the tests used for production or field testing.NOTE For the purpose of remaining clauses, the term “unit” is used to mean “fan coil unit” as defined in 3.1.
