18、ittee CEN /TC 129, “Glass in building“, the secretariat of which is held by IBN. 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 2004, and conflicting national standards shall be withdraw
19、n at the latest by December 2004. This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association, and supports essential requirements of EU Directive(s). For relationship with EU Directive(s), see informative annex Z, which is an integ
20、ral part of this document. This European Standard “Glass in Building - Insulating glass units” consists of the following Parts Part 1: Generalities, dimensional tolerances and rules for the system description. Part 2: Long term test method and requirements for moisture penetration. Part 3: Long term
21、 test method and requirements for gas leakage rate and for gas concentration tolerances. Part 4: Methods of test for the physical attributes of edge seals. Part 5: Evaluation of Conformity. Part 6: Factory production control and periodic tests. The annexes A and B are normative, and annex C is infor
22、mative. 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, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, La
23、tvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Slovakia, Slovenia, Spain, Sweden, Switzerland and United Kingdom. EN 1279-1:2004 (E) 4 1 Scope This European Standard is the product standard for insulating glass units, which defines insulating glass units, and ensures by m
24、eans of the evaluation of conformity to this standard that over time: energy savings are made because the U-value and solar factor do not change significantly; health is preserved because sound reduction and vision do not change significantly; safety is provided because mechanical resistance does no
25、t change significantly. It covers characteristics that are of importance for trade. Marking conditions are included. NOTE 1: For glass products with electrical wiring or connections for, e.g. alarm or heating purposes, other directives, e.g. Low Voltage Directive, may apply. The main intended uses o
26、f the insulating glass units are installations in windows, doors, curtain walling, roofs and partitions where there exists protection against direct ultraviolet radiation at the edges. NOTE 2: In cases where there is no protection against direct ultraviolet radiation at the edges, such as structural
27、 sealant glazing systems, additional European technical specifications should be followed. Units that are intended for artistic purposes are excluded from this standard. This Part of this European standard, which is inextricably bound up with the other Parts of the standard, covers the materials, th
28、e rules for the system description, the optical and visual quality and the dimensional tolerances for insulating glass units. 2 Normative references This European Standard incorporates, by dated or undated reference, provisions from other publications. These normative references are cited at the app
29、ropriate places in the text and the publications are listed hereafter. For dated references, subsequent amendments to or revisions of any of these publications apply to this European Standard only when incorporated by amendment or revision.

37、inition and description prEN 14321-1 Glass in Building - Thermally toughened alkaline earth silicate safety glass - Part 1: Definition and description 3 Definitions For the purpose of this standard, the following definitions apply. 3.1 insulating glass unit (IGU) an assembly consisting of at least t
38、wo panes of glass, separated by one or more spacers, hermetically sealed along the periphery, mechanically stable and durable (see 5.1). NOTE: systems are available where the spacer and hermetic seal are included within a single edge sealing system. EN 1279-1:2004 (E) 6 3.2 system a range of insulat
39、ing glass units with a common edge seal profile, edge seal materials and edge seal components as described in the system description. The range having a similar edge seal performance, e.g. moisture penetration index, gas loss rate. 3.3 system description description of components and the edge seal o
40、f the insulating glass unit in terms relevant to identification, and in terms relevant to edge seal performance, e.g. moisture penetration index, gas loss rate. 3.4 permeation geometry the geometry of that part of the edge seal of the insulating glass unit through which the vapour and gas transmissi
41、on takes place. For an example, see figure 1. NOTE: For TPS-type systems the permeation is through the body of the system rather than around the spacer and through the sealant. M o i s t u r e p e n e t r a t i o n G a s l o s s Figure 1 Example of a permeation geometry 3.5 cavity (cavities) the gap
42、(s) between the panes of an insulating glass unit. 3.6 channel a profile covering and protecting the edges and/or making it possible to install the unit in frames originally designed for single glass. 3.7 corner piece a joint piece that acts as a corner of the spacer frame. EN 1279-1:2004 (E) 7 3.8
43、dehydrated air or gas air or other gas with a low water vapour partial pressure which, when introduced into the cavity, eliminates the risk of condensation. 3.9 desiccant a product designed to lower the water vapour partial pressure inside the insulating glass unit. 3.10 desiccant cartridge a metal
44、or plastic section, containing a desiccant, placed somewhere in the cavity. 3.11 edge seal the processed edge of an insulating glass unit, designed to ensure that moisture and gas transmissions between the inside and outside of the unit are limited, designed with a certain mechanical strength, and d
45、esigned with a certain physical and chemical stability. 3.12 glass pane (also referred to as glass component) one sheet of glass. 3.13 inner sealant a sealant which, when applied, is in contact with the cavity of the insulating glass units. 13.14 joint piece a piece that connects parts of a spacer.
46、3.15 outer sealant a sealant which, when applied, is in contact with the environment outside the insulating glass units 2 . 3.16 sealant organic material that, after application, has sufficient mechanical properties of cohesion and of adhesion to glass and/or spacer for use in edge seals. For the pu
47、rpose of this standard, silicone sealant is considered to be organic. 3.17 spacer a component used to separate the panes and control the width of the gap at the edge of the unit. 3.18 external condensation condensation appearing on the glass panes of an insulating glass unit either on the room side
48、surface or on the external surface. 3.19 internal condensation condensation appearing on the glass panes within the cavity of an insulating glass unit. 1In the case of single seal insulating glass units, the inner sealant is the same as the outer sealant. 2In the case of single seal insulating glass units, the outer sealant is the same as the inner sealant EN 1279-1:2004 (E) 8 3.20 absolute limit a value of a parameter, defined in the system description (annex A), which when exceeded requires: remedial action in manuf
