27、re describing the different pressure level was added; a specification for the water used has been added in 4.3.2.1; the requirements concerning safety arrangements (4.6) were revised and clarified; 4.7.4 concerning pressure maintaining control device was revised. According to the CEN-CENELEC Interna

28、l Regulations, the national standards organisations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece, Hungary, Iceland, Irel

BS EN 12828:2012+A1:2014 EN 12828:2012+A1:2014 (E)5 Introduction The subjects covered by CEN/TC 228 are the following: desi

30、gn 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 calculation of the design heat loss and heat load; methods for calculation of the energy performan

31、ce 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 addressed to the system as a whole and not dealing with requirements to the products within the syste

32、m. Where possible, reference is made to other CEN or ISO standards, e.g. product standards. However, use of products complying with relevant product standards is no guarantee of compliance with the system requirements. The requirements are mainly expressed as functional requirements, i.e. requiremen

33、ts 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 requirements may be used if fulfilment can be proved. Heating systems differ among the member countrie

34、s 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 with national regulations, the latter should be followed. BS EN 12828:2012+A1:2014 EN 12828:2012+A1:201

35、4 (E)6 1 Scope This European Standard specifies design criteria for water based heating systems in buildings with a maximum operating temperature of up to 105 C. In case of heating systems with maximum operating temperatures over 105 C other safety aspects than those described in 4.6 may apply. The

36、other clauses of this European Standard are still valid for those systems. This European Standard does not amend product standards or product installation requirements. This standard covers the design of: heat supply systems; heat distribution systems; heat emission systems; control systems. This Eu

37、ropean 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. This European Standard does not cover requirements for installation or co

38、mmissioning or instructions for operation, maintenance and use of water based heating systems. This European Standard does not cover the design of fuel and energy supply systems. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are
