21、s thickness), tests, marking and designation of heated glass panes for ships rectangular windows (H series: see ISO 3903:1993, subclause 4.1.3). It includes the conditions with which they are required to comply to ensure the safety of ships in times of frost or snow, particularly during manoeuvres i
22、n port. Heated glass panes are used on ships principally for the windows of wheel-houses and bridges, and also in enclosed locations used for look-out and manoeuvring purposes. This International Standard specifies heated glass panes which are intended for use at temperatures down to p40 C. 2 Normat
23、ive references The following standards contain provisions which, through reference in this text, constitute provisions of this International Standard. At the time of publication, the editions indicated were valid. All standards are subject to revision, and parties to agreements based on this Interna
24、tional Standard are encouraged to investigate the possibility of applying the most recent editions of the standards indicated below.

All the optical requirements shall apply whether the temperature control gear is cyclic or whether the heate
28、d glass pane is equpped with a temperature-regulating device (for example a thermostat). However, these optical qualities are not required at the periphery of the glass pane within a band 50 mm wide measured from the edge of the window frame. 3.2 Visibility Heated glass panes shall ensure perfect vi
29、sibility in all weathers, avoiding the formation of mist or frost, in relation to the power loading (see Table 5). They shall, in addition, ensure maximum efficiency of the windscreen wipers when operating in conditions of frost or snow. They shall not cause any significant reduction in the resolvin
30、g power of the eye or of binoculars when a distant object is observed at normal incidence through the glass. Tinted glass shall not be used. When discrepancies of interpretation about visibility arise, they are subject to agreement between purchaser and manufacturer. 1)To be published. (Revision of

32、ular of beacons and lights on buoys. When discrepancies of interpretation about deterioration in colour arise, they are subject to agreement between purchaser and manufacturer. 4 Construction of glass pane 4.1 General A complete mountable heated glass pane that meets the requirements of this Interna
33、tional Standard is a component unit, consisting of a laminated glass pane and a firmly mounted device for the electrical connection. 4.2 Composition, types and materials The composition of the laminated glass pane shall be as shown in Figure 1 and Table 1. A distinction is made between type A, with
34、two glass panes, and type B, with three glass panes.

The maximum allow
36、able pressure of the carrier pane shall be as given in ISO 3903. 4.2.1.2 This carrier pane shall be manufactured from clear toughened safety glass in accordance with ISO 21005. 4.2.2 Cover pane The cover pane carries or protects the heating element. It is thinner than the carrier pane. The material
37、shall be clear toughened or semi-toughened safety glass. 4.2.3 Heating element The heating element consists of a thin wire, a transparent conductive film or a transparent conductive coating. 4.2.4 Inter-layer The inter-layer consists of a thin plastics material (foil) of 0,76 mm minimum thickness. 4
38、.3 Protection of edges In order to avoid any penetration of humidity or any other form of chemical attack between the layers of the laminate, and to protect the edges against impact as well as to ensure durable electrical insulation, the periphery of the glass pane shall be protected by materials su
39、ch as silicone, rubbers, polysulfides or similar, compatible with the plastics inter-layers of the laminate. This edge protection shall be bonded to the edge and not thicker than 3 mm (see Figure 2). Dimensions in millimetres Figure 2 Protection of edges Licensed Copy: sheffieldun sheffieldun, na, S
