This European Standard specifies a set of assumptions, requirements and validation tests for procedures used for the calculation of the annual energy needs for space heating and cooling of a room in a building where the calculations are done with a time step of one hour or less.
This European Standard does not impose any specific numerical technique for the calculation of the room heating or cooling need and the internal temperatures of a room.
The purpose of this European Standard is to validate calculation methods used to:
-   assess the energy performance of each room of a building;
-   provide energy data to be used as interface with system performance analysis (heating, cooling, ventilating, lighting, domestic hot water etc).
The validation procedure is used to check the energy need for space heating and cooling based on a transient sensible heat balance model, taking into account:
-   the external surface heat balance;
-   the conduction through the building envelope;
-   the thermal capacities of external and internal structures;
-   the internal surface heat balance;
-   the air heat balance;
-   the heat balance solution method.
All other aspects are given either by prescribed boundary conditions or by input data and are not part of the model validation. It is assumed, that for all these other matters e.g. embedded heating and cooling systems, prescriptive models have to be used according to existing European Standards.
The system performance analysis and moisture balance are not within the scope of this European Standard.

This European Standard defines the requirements for buffers with 105 mm, 110 mm and 150 mm stroke for vehicles or units which use buffers and screw coupling at the coupling interface with other interoperable rolling stock. It covers the functionality, interfaces and testing procedures, including pass fail criteria, for buffers. It defines the different categories of buffers, the space envelope, static and dynamic characteristics and energy absorption. It includes a calculation method to determine the minimum size of the buffer head to avoid override between buffers. It defines the static and dynamic characteristics of the elastic systems. It also defines the requirements for buffers with integrated crash elements (crashworthy buffers) for tank wagons only according to RID. The requirements of this European Standard also apply to locomotives and passenger coaches which have to meet the crashworthiness requirements of EN 15227 for buffers in normal service only. The properties for the energy absorbing function are defined in EN 15227 and the requirements specified in Clause 7 for tank wagons according to RID are not applicable to locomotives and passenger coaches. Diagonal buffers are excluded from this European Standard. For vehicles which have to comply with crashworthiness requirements (locomotives, cab cars or passenger coaches according to EN 15227, tank wagons according to RID), typically crashworthy buffers (buffers with a deformable housing and/or the need for an opening in their mounting flange) or buffers which form part of a combined system consisting of a special buffer (e.g. middle flange buffer) and a deformation element are used. For these types of buffers, interoperability is possible, but interchangeability with freight wagon buffers is not required, and therefore the requirements of 5.2 (Fixing on vehicle and interchangeability), 5.3 (Buffer dimensions) do not apply, those of 5.4 (mechanical characteristics of buffers) and 5.6 (marking) apply with restrictions.

This standard specifies the terms, definitions, test conditions, test methods and requirements for rating the performance of air conditioners and liquid chilling packages, with electrically driven compressors and with evaporatively cooled condenser when used for space cooling. The evaporatively cooled condenser is cooled by air and by the evaporation of external additional water. This additional external water is fed by a specific water supply circuit or by a water tank.
This standard does not apply to air-to-air and air-to-water air conditioners with a condenser cooled by air and by the evaporation of water condensed on their evaporator.
This standard does not apply to units equipped with a water tank or with a continuous water circuit supply that cannot operate without water feeding.
This standard applies to factory-made units which can be ducted.
This standard applies to factory-made units of either fixed capacity or variable capacity by any means.
Packaged units, single split and multisplit systems are covered by this standard.
With regard to units consisting of several parts, this standard applies only to those designed and supplied as a complete package.
Installations used for industrial processes cooling are not within the scope of this standard.
NOTE   All the symbols given in this text should be used regardless of language.

This document establishes requirements for determining, in accordance with a standardized procedure, the sound power level emitted into the surrounding air by air-conditioners, heat-pumps, liquid chilling packages with electrically driven compressors when used for space heating and/or cooling, as described by the standards EN 14511 and dehumidifiers as described by the standard EN 810.
It is emphasized that this measurement standard only refers to airborne noise.
This standard applies to factory-made units of either fixed capacity or variable capacity by any means.
It covers:
- packaged units, single split and multisplit systems, except water cooled multisplit systems,
- air-to-air air conditioners which evaporate the condensate on the condenser side,
- chillers, shelters, roof-tops.
- inverters.
In the case of units consisting of several parts, this standard applies only to those designed and supplied as a complete package, except for liquid chilling packages with remote condenser.
This standard does not cover:
- units having their condenser cooled by air and by the evaporation of external additional water,
- heat pumps for sanitary hot water, although some definitions can be applied to these units,
- units using transcritical cycles, e.g. with CO2 as refrigerant,
- installations used for heating and/or cooling of industrial processes.
This standard offers ways to determine the sound power level of units. Some of them are specifically adapted to provide results with low uncertainties, by using laboratory class acoustic methods and highly controlled working conditions. Those measurements are suitable for certification, labelling and marking purposes.
In some cases, the target and/or the environment of the measurements do not allow such precision-class results. This standard also offers ways to assess sound power levels with acceptable accuracy even though acoustic methods and/or working conditions are not laboratory-type, e.g. in situ or quality control measurements. This European Standard gives two classes of measurements and results, according to the test environment:;Class A measurements correspond to controlled working conditions (standard or application rating conditions). It is defined by the respect to the tolerances of Table 2.;Class B measurements correspond to the case where the range defined by the tolerances of Table 2 cannot be fulfilled. In both classes, precision or engineering class acoustic methods should be applied. The choice of the acoustic measurement method is done in accordance with EN ISO 3740 and EN ISO 9614 depending on the type of surrounding acoustic fields (diffuse or free field, enclosed or open space), and the available instrumentation. Whatever the current working conditions, the reference of acoustic standard shall be reported, with explicit mention of its accuracy class.

This part of EN 255 specifies the terms and definitions for the rating and performance of air and water cooled air conditioners, liquid chilling packages, air/air, air/water and water/water heat pumps with electrically driven compressors as well as the properties of the units when used in heating mode. When these units are used for space cooling, then prEN 814-1 applies; when these units are used for cooling and heat recovery, then prEN 12055 applies. This standard does not specifically apply to heat pumps for sanitary hot water, although certain definitions can be applied to these.

This part of EN 255 specifies minimum requirements which ensure that an air or water cooled air conditioner, liquid chilling packages, air/air, water/air or water/water heat pump, with electrically driven compressor, is fitted for theuse designated by the manufacturer, when used for space heating or for hot sanitary water. When these units are used for space cooling, then prEN 814-3 applies; when these units are used for cooling and heat recovery, then prEN 12055 applies.

This European Standard establishes requirements for determining, in accordance with a standardized procedure, the noise (parameter: sound power level) emitted into the surrounding air by air conditioners, heat pumps or dehumidifiers with electrically-driven compressors. The frequency range used in this pre-standard is from 125 Hz to 4000 Hz. Three methods for determining the sound power levels are specified in order to avoid unduly restricting existing facilities and experience.
