13、ization) 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 right to
14、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. International Stand
15、ards 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 an Inte
16、rnational 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.

19、the rapid change of light intensity from such devices in a vertical cross-section of the projected beam. It also specifies (see Annex A) methods for testing the magnetic-base mountings used to install special warning lamps directly on the steel sheet of the roof or body of a vehicle (special warning
20、 lamps of Category D). NOTE In certain countries and international bodies, the term “light” is sometimes used instead of “lamp”. 2 Normative references The following referenced documents are indispensable for the application of this document.

28、 4); Category C: single-stem-mounted lamp (see Figure 5); Category D: magnetic-base-mounted lamp (see Figure 6); Category E: warning signal unit (see Figure 7). 5 Intermediate quick-release devices An intermediate quick-release device may be used if it accepts warning lamps of Categories A, B or C,
29、if it yields the desired accuracy, and if national requirements so permit. 6 Requirements for mounting 6.1 Interchangeability The warning lamps shall comply with the requirements of Figures 1 to 7, as appropriate. 6.2 Mounting accuracy When mounted correctly, each lamp shall be within 1 of the posit
30、ion specified. In the case of intermediate quick-release devices, the mounting shall be made on a fixture representing the fixing zone for which it is BSISO4148:2004IS:8414 O4002(E) I SO 4002 All irthgs ersedevr 3intended. To check mounting accuracy, the lamp shall be mounted five times on an approp
31、riate test fixture, and its attitude determined. In no case shall the inclination vary by more than 1 from the mounting plane for Categories B, C and D or from a plane perpendicular to the mounting tube axis for Category A. 6.3 Geometric visibility The apparent surface of a warning lamp shall be vis
32、ible within the field defined by the following angles of geometric visibility: a) horizontal angle: 360; b) vertical angle : 1) = 4 for blue special warning lamps, 2) = 8 for amber special warning lamps. The vertical angle below the horizontal plane may be smaller if the geometric visibility of the
33、lamp is met at points located 1 m above the surface on which the vehicle stands and at 20 m from the vehicle. In the case where more than one lamp is fitted, the requirements of this International Standard are met if at least one lamp is visible under the conditions specified. 7 Identification Ident
34、ification shall include the following: a) the manufacturers name, the model number and the category of device; b) the colour and any special conditions (insulated return, ADR, etc.).
