This European Standard shal
12、l be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by February 2012, and conflicting national standards shall be withdrawn at the latest by February 2012. Attention is drawn to the possibility that some of the elements of this do
13、cument 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 ISO 12543-5:1998.

16、tandardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the ri
17、ght to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. Internationa
18、l Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as
19、an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights.

23、ed safety glass for use in building. This part of ISO 12543 is not applicable to panes having an area less than 0,05 m2. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated
24、 references, the latest edition of the referenced document (including any amendments) applies. ISO 12543-1, Glass in building Laminated glass and laminated safety glass Part 1: Definitions and description of component parts 3 Terms and definitions For the purposes of this document, the terms and def
25、initions given in ISO 12543-1 and the following apply. 3.1 displacement d misalignment at any one edge of the constituent glass panes or plastic glazing sheet material making up the laminated glass See Figure 2. 4 Dimensions and limit deviations 4.1 Thickness 4.1.1 Nominal thickness The nominal thic
26、kness of laminated glass shall be the sum of the nominal thicknesses of the constituent panes of glass, plastic glazing sheet material and the interlayers. BS EN ISO 12543-5:2011ISO 12543-5:2011(E) 2 ISO 2011 All rights reserved4.1.2 Limit deviation on thickness 4.1.2.1 Limit deviation on thickness
27、of folio laminated products The limit deviations on thickness of laminated glass shall not exceed the sum of the limit deviations of the constituent glass panes specified in the basic products standards; see ISO 12543-1:2011, Annex A. NOTE 1 For the appropriate CEN standards, see ISO 12543-1:2011, A
28、nnex B. If the total interlayer thickness is less than or equal to 2 mm, an additional limit deviation of 0,1 mm applies. If the total interlayer thickness is greater than 2 mm, an additional limit deviation of 0,2 mm shall apply. The thickness limit deviation for plastic glazing sheet material shal
29、l be assumed to be the same as a float glass of the same nominal thickness. NOTE 2 If the plastic glazing sheet material is covered by a standard, the actual limit deviations on thickness can be used. EXAMPLE A laminated glass made from two sheets of float glass of 3 mm nominal thickness and a folio
30、 interlayer of 0,5 mm. The limit deviation of 3 mm float glass is given as 0,2 mm and the limit deviation of the folio interlayer is 0,1 mm. Therefore, the nominal thickness is 6,5 mm and the limit deviation is 0,5 mm. 4.1.2.2 Limit deviations on thickness of cast-in-place products The limit deviati
31、ons on thickness of cast-in-place laminated glass shall not exceed the sum of the limit deviations of the constituent glass panes specified in the basic products standards and the limit deviations of the cast-in-place interlayers. The thickness limit deviation for plastic glazing sheet material shal
32、l be assumed to be the same as a float glass of the same nominal thickness. NOTE If the plastic glazing sheet material is covered by a standard, the actual limit deviations on thickness can be used. The thickness limit deviations of cast-in-place interlayers shall be in accordance with Table 1. Tabl

NOTE Thermally toughened safety glass, heat-soaked thermally toughened safety glass and heat-strengthened glass can be individually worked prior to thermal treatment in accordance with an
38、applicable standard. The edges of fire-resistant laminated glass and fire-resistant laminated safety glass can be protected by an adhesive tape. 5.2 Cut edge These are either originally cut edges of the constituent glass panes not subsequently worked (see Figure 3), or the edges of the laminated gla

43、polished edge with an angle not exceeding 60. The limit deviation on a bevel angle shall be 3 (see Figure 9). For greater angles and their limit deviations, the manufacturer should be contacted. The nominal dimension, L or H, shall be reduced by 2 mm to 3 mm to cater for an arrissed edge. Dimensions
