16、Foreword This document (EN 1264-1:2011) has been prepared by Technical Committee CEN/TC 130 “Space heating appliances without integral heat sources”, the secretariat of which is held by UNI. This European Standard shall be given the status of a national standard, either by publication of an identica
17、l text or by endorsement, at the latest by December 2011, and conflicting national standards shall be withdrawn at the latest by December 2011. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN and/or CENELEC shall not be held r
18、esponsible for identifying any or all such patent rights. This document supersedes EN 1264-1:1997. The series of European Standards EN 1264 “Water based surface embedded heating and cooling systems“ consists of the following parts: Part 1: Definitions and symbols; Part 2: Floor heating: Prove method
19、s for the determination of the thermal output using calculation and test methods; Part 3: Dimensioning; Part 4: Installation; Part 5: Heating and cooling surfaces embedded in floors, ceilings and walls Determination of the thermal output. The main change with respect to EN 1264-1:1997 consists in th
20、e expansion of the scope over floor heating, now additionally includes ceiling and wall heating as well as cooling surfaces in floors, ceilings and walls. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this Eu
21、ropean Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland and

DIN EN 1264-1:2011-09 EN 1264-1:2011 (E) 4 1 Scope This European Standard is applicable to water based surface embedded heating and cooling systems in residential, office and other buildings, the use of which corresponds to or is similar to that of residential buildings. This Eu
23、ropean Standard applies to heating and cooling systems embedded into the enclosure surfaces of the room to be heated or to be cooled. It also applies as appropriate to the use of other heating media instead of water. 2 Normative references The following referenced documents are indispensable for the
