18、een prepared by Technical Committee CEN/TC 228 “Heating systems in buildings“, the secretariat of which is held by DS. This European Standard shall be given the status of a national standard, either by publication of an identical text orby endorsement, at the latest by April 2005, and conflicting na

19、tional standards shall be withdrawn at the latest byApril 2005. The subjects covered by CEN/TC 228 are the following: -Design of heating systems (water based, electrical etc.);-Installation of heating systems;-Commissioning of heating systems;-Instructions for operation, maintenance and use of heati

20、ng systems;-Methods for calculation of the design heat loss and heat loads; -Methods for calculation of the energy performance of heating systems.Heating systems also include the effect of attached systems such as hot water production systems.All these standards are systems standards, i.e. they are

21、based on requirements addressed to the system as a whole and not dealing with requirements to the products within the system. Where possible, reference is made to other European or International Standards, a.o. product standards. However, use of products complying with relevant product standards is

22、no guarantee of compliance with the systemrequirements.The requirements are mainly expressed as functional requirements, i.e. requirements dealing with the function ofthe system and not specifying shape, material, dimensions or the like. The guidelines describe ways to meet the requirements, but oth

23、er ways to fulfil the functional requirements might be used if fulfilment can be proved. Heating systems differ among the member countries due to climate, traditions and national regulations. In somecases requirements are given as classes so national or individual needs may be accommodated. In cases

24、 where the standards contradict with national regulations, the latter should be followed. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Cyprus, Czech Republic, Denmar

26、pecifies the requirements for the installation and commissioning of water-based heating systems in buildings with a maximum operating temperature of 110 oC and a maximum operating pressure of 6 bar. This document covers the systems requirements for the installation and commissioning of individual co

27、mponents ofthe system (e.g. heat generators, pumps, controls). It does not cover the specific commissioning requirements forthese components.This document does not cover the installation or commissioning of attached systems (e.g. air conditioning, domestichot water or ventilation systems). This docu

28、ment covers only the technical requirements, and does not cover any commercial or contractual arrangements between parties. 2 Normative references The following referenced documents are indispensable for the application of this document.
