This European Standard gives guidance on the preparation of manufacturer's instructions for the installation, operation and maintenance of heat exchangers. Meeting the recommendations in this standard does not remove the manufacturers/installers responsibility to provide all necessary specific information to ensure the safe and efficient working of their equipment.

This standard applies to series produced water to water heat exchangers, for district heating appliances and its purpose is to establish uniform methods to test and ascertain the following: - product identification; - performance characteristics; - pressure drop. This European standard does not cover technical safety aspects.

This European Standard applies to forced circulation air-cooling or air-heating coils operating:a) with an evaporating or condensing refrigerant;b) with a cooling or heating fluid;c) without fans. Operation with steam is not part of the standard.

This standard specifies physical properties (mechanical, optical etc.) for nominally afocal sunglasses and sunglare filters intended for protection againstsolar radiation for general use, for social and domestic purposes, including road use and driving. For sunglasses and sunglare filters for industrial use, EN 166:1995 and EN 172:1994 apply. Guidance for selection and use of these filters is given in (informative) annex A. This standard does not apply to eyewear for protection against radiation from artificial light sources, such as those used in solaria.

This European Standard specifies general terms and calculations used in deter- mining performance of heat exchangers including related theory and general test procedure. This European Standard applies to heat exchangers classified according to the general arrangement of heat transfer specified by heat transfersurface types of 4.1 and 4.2 of prEN 247:1996. This European standard applies when referenced by the various branch applicationstandards. The specific application European standards shall be the prime reference documents.

This European Standard specifies the methods and accuracy of measurement for temperature, pressure, fluid quality and massflow of different fluids and how to determine the pressure drops across a heat exchanger. Measurements are restricted to those necessary for establishing the performance of heat exchangers classified in prEN 247 using the fluids listed in prEN 247. This E.S. applies when reference by the various branch application standards. The specific application European Standards shall be the prime reference documents.

This standard specifies methods to be used for laboratory testing of air-to-air heat recovery devices or those recovering heat from flue gases of heating appliances in buildings (except process-process applications) to obtain rating data. It gives test requirements and procedures for performing such tests and specifies input criteria required for tests to verify performance data given by the manufacturer.
For the purposes of this standard, the term exhaust air may also be taken to mean the products of combustion.
This European Standard is applicable to the following categories of heat exchangers:
Category I       Recuperators
Category II      With intermediary heat transfer medium
Category IIa    - without phase-change
Category IIb    - with phase-change (heat pipe, ...)
Category III     Regenerators (containing accumulating mass)
Category IIIa   - non hygroscopic
Category IIIb   - hygroscopic
Heat recovery devices with exchangers and intermediary heat transfer medium without phase-change (category IIa) are to be tested as one unit including pump and pipe system between the coils.
This European Standard prescribes test methods for determining:
a) the external leakage;
b) the internal leakage of exhaust air to the supply-air within the device at a given pressure difference between air ducts, for recovery devices of categories I and II;
c) the carry-over of exhaust air to the supply air in recovery devices of category III;
d) the temperature and humidity ratios;
e) the pressure drop of exhaust-air and supply-air sides.

This European Standard specifies methods to be used for testing of air-to-air heat recovery components (HRC). The main purpose of the HRC shall be to
- preheat or heat and/or
- precool or cool
supply air in ventilation systems or air conditioning systems. Optional HRC can exchange air humidity between exhaust and supply air. The HRC contain the heat exchangers and all necessary features and auxiliary devices for the exchange of sensible heat and (if available) air humidity between exhaust air and supply air. The HRC will be installed in casings or air ducts. If fans are part of the test unit, the effect of the fan power on the measured values shall be corrected.
This European Standard specifies procedures and input criteria required for tests to determine the performance of a HRC at one or several test conditions, each of them with continuous air flows, air temperatures and humidities at both inlet sides. Three different test types are covered:
- Laboratory testing of HRC
- Laboratory testing of HRC installed in non-residential air handling
units (definition according Commission Regulation(EU) No 1253/2014) in design configuration
- On-site (field) testing of HRC in non-residential air handling units
or systems in operation configuration.
This European Standard is applicable to recuperators and regenerators intended for exchange of sensible heat and optionally for exchange of air humidity.
This European Standard prescribes test methods for determining:
1. the temperature and humidity efficiency
2. the pressure drop of exhaust air and supply air sides
3. possible internal leakages; exhaust air transfer ratio (EATR) and
outdoor air correction factor (OACF)and
4. auxiliary energy used for the operation of the HRC.
HRC using heat pumps are not covered by this standard.

This document specifies methods to be used for testing of air-to-air heat recovery components (HRC). The main purpose of the HRC is to exchange heat between exhaust air and supply air in order to save energy, which results in
—   preheat or heat, and/or
—   precool or cool
supply air in ventilation systems or air conditioning systems. Optionally HRC can exchange air humidity between exhaust and supply air. The HRC contains the heat exchangers and all necessary features and auxiliary devices for the exchange of sensible heat and (if available) air humidity between exhaust air and supply air. The HRC will be installed in casings or ducts. If fans are part of the test unit, the effect of the fan power on the measured values will be corrected.
This document specifies procedures and input criteria required for tests to determine the performance of a HRC at one or several test conditions, each of them with continuous and stationary air flows, air temperatures and humidities at both inlet sides. Three different test types are covered:
