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 October 2006, and conflictin
16、g national standards shall be withdrawn at the latest by January 2008. This European Standard supersedes EN 12352:2000. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium,

18、Scope This European Standard specifies the requirements for individual electrically operated light devices, called warning lights, emitting a continuous or regular intermittent light of a single colour which, by their colour and position alone, are used to warn, inform or guide road users. It specif
19、ies the requirements for visual, structural and operational performances and the relevant test methods to be used. These devices rely upon existing furniture to provide the mounting. This European Standard is not applicable to lighting devices which convey messages by additional means (e.g. variable
20、 message signs) or which convey a mandatory instruction (e.g. traffic signals) or which are covered by vehicle lighting regulations. This European Standard does not consider horizontal loads because it is the mounting to which they are fixed, which is not covered by this European Standard, which has
21、 to resist applied horizontal loads. 2 Normative references The following referenced documents are indispensable for the application of this European Standard. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any a

NOTE 2 All the values given for the luminous intensity in Table 1 are given as actual continuous values for stea
41、dy warning lights and are given as effective luminous intensity for flashing warning lights. Except where limited to a specific Class F designation, shown in brackets, the luminous intensity values given apply to both steady and flashing warning lights in the same L Class. In order to take account o
