15、Committee CEN/TC 129 “Glass in building”, the secretariat of which is held by NBN. 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 December 2011, and conflicting national standards shall be withdr
16、awn 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 responsible for identifying any or all such patent rights. This document supersedes EN 675:1997. The main cha
17、nge in this edition is that the internal and external heat transfer coefficients have been amended slightly to reflect changes to EN 673. Clarification is also given in the scope that the procedure specified in this European Standard should generally only be considered when the calculation method de
18、tailed in EN 673 is inappropriate or unsuitable. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, F

DIN EN 675:2011-09 EN 675:2011 (E) 4 Introduction CEN/TC 129/WG 9 “Light and energy t
20、ransmission, thermal insulation“ prepared a working draft based on the document ISO/DIS 10293 “Glass in building - Determination of steady-state U values (thermal transmittance) of multiple glazing - Heat flow meter method“, document that was prepared by ISO/TC 160, “Glass in building“. This was pub
21、lished in 1997 as EN 675. The document for the calculation of the overall U value of windows, doors and shutters (see 2) gives normative reference to the U value evaluated for the glazing components according to this standard. For the purposes of product comparison, a vertical position of the glazin
22、g is specified (see Clause 10). U values evaluated according to the present standard are used for product comparison as well as for other purposes, in particular for predicting: heat loss through glazing; conduction heat gains in summer; condensation on glazing surfaces; the effects of the absorbed
23、solar radiation in determining the solar factor (see 1). Reference should be made to 2, 3, 4 or other European Standards dealing with heat loss calculations for the application of glazing U values determined by this Standard.
