The work of preparing International Standards is normally carried out through ISO technicalco
9、mmittees. Each member body interested in a subject for which a technical committee has been established hasthe right to be represented on that committee. International organizations, governmental and non-governmental, inliaison with ISO, also take part in the work. ISO collaborates closely with the
10、International ElectrotechnicalCommission (IEC) on all matters of electrotechnical standardization.International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3.Draft International Standards adopted by the technical committees are circulated to the member bo

15、marking of transparent and translucent glass products,which will be described in future International Standards on basic or processed glass products, in assemblies for usein building and intended to provide some degree of fire-resistance.2 Normative referencesThe following normative documents contai
16、n provisions which, through reference in this text, constitute provisions ofthis International Standard. For dated references, subsequent amendments to, or revisions of, any of these publica-tions do not apply. However, parties to agreements based on this International Standard are encouraged to inv
17、esti-gate the possibility of applying the most recent editions of the normative documents indicated below. For undatedreferences, the latest edition of the normative document referred to applies.

19、te fire.If affected by heat, glass may fracture by thermal shock or may soften and then not be held by the frame. Only certaintypes of glazed assemblies are, therefore, recognized as fire-resisting. The ability of glazed assemblies to resist firedepends on the type of glass product, glazing method,
20、frame type, pane size, fixing method and the type ofconstruction surrounding the glazed area.Some transparent and translucent glazed assemblies can meet requirements for stability and integrity (RE), and insome cases insulation (REI, where R is for resistance, E for integrity and I for insulation).N

23、ifferently in case of fire, the type shall be classified into one of the followingcategories.a) Class REGlazed assemblies of fire-resistance according to class RE under the fire conditions as defined in ISO 834-1 pro-vide, for a given time, stability and integrity. The temperature of the unexposed s

25、al and surrounding construction shall be such that the glazed assembly as a wholecorresponds to the test report.Glazings of class RE could, for example, contain glass blocks, glass with a low coefficient of thermal expansion, or glass ceramics, glass toughened by thermal or chemical treatment, wired
26、 glass, flat glass in small panes, or laminated glass,in single or multiple glazings.Glazings of class REI could, for example, contain some types of glass blocks, or some types of laminated glazings in single or multiple glazings.6 Test requirements6.1 SpecimensA specimen, for the purposes of this I

28、1999, subclause 5.5.12, with at least one thermocouple for the measurement of the maximum tem-perature on the glazing.Copyright International Organization for Standardization Provided by IHS under license with ISONot for ResaleNo reproduction or networking permitted without license from IHS-,-,-ISO
