20、 by DS. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by September 2003, and conflicting national standards shall be withdrawn at the latest by March 2004. Annexes A, B, C, D and ZA are informative
21、. This document includes a Bibliography. 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 heating systems; methods for
22、 calculation of the design heat loss and heat load; 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 system standards, i.e. they are based on requirements ad
23、dressed to the system as a whole and not dealing with requirements to the products within the system. Where possible, reference is made to other CEN or ISO standards, a.o. product standards. However, use of products complying with relevant product standards is no guarantee of compliance with the sys
24、tem requirements. The requirements are mainly expressed as functional requirements, i.e. requirements dealing with the function of the system and not specifying shape, material, dimensions or the like. The guidelines describe ways to meet the requirements, but other ways to fulfil the functional req
25、uirements might be used if fulfilment can be proved. Heating systems differ among the member countries due to climate, traditions and national regulations. In some cases requirements are given as classes so national or individual needs may be accommodated. In cases where the standards contradict wit
26、h 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, Czech Republic, Denmark, Finland, France, Germany, Greece, Hungar
27、y, Iceland, Ireland, Italy, Luxembourg, Malta, Netherlands, Norway, Portugal, Slovak Republic, Spain, Sweden, Switzerland and the United Kingdom. Licensed Copy: London South Bank University, South Bank University, 02/02/2009 03:34, Uncontrolled Copy, (c) BSI EN 12828:2003 (E) 5 1 Scope This standard
28、 specifies design criteria for water based heating systems in buildings with a maximum operating temperature of up to 105C. In case of heating systems with maximum operating temperatures over 105C other safety aspects than those described in 4.6 may apply. The other clauses of this standard are stil
29、l valid for those systems. This standard does not cover additional safety requirements which may be applicable to heating systems greater than 1 MW design heat load. This standard does not amend product standards or product installation requirements. This standard covers the design of: heat supply s
30、ystems; heat distribution systems; heat emission systems; control systems. This standard takes into account heating requirements of attached systems (e.g. domestic hot water, process heat, air conditioning, ventilation) in the design of a heat supply, but does not cover the design of these systems.
31、This standard does not cover requirements for installation or commissioning or instructions for operation, maintenance and use of water based heating systems. This standard does not cover the design of fuel and energy supply systems. 2 Normative references This European Standard incorporates by date
