0 General Introduction
0.1 Scope
This part of GB 7000 specifies general requirements for luminaires, incorporating electric light sources for operation from supply voltages up to 1,000V. The requirements and related tests of this part cover: classification, marking, mechanical construction, electrical construction and photobiological safety.
Each chapter of this part is read in conjunction with this Chapter 0 and with other relevant chapters to which reference is made.
Each part of GB 7000.2 details requirements for a particular type of luminaire or group of luminaires on supply voltages not exceeding 1,000V. These parts are published separately for ease of revision and additional chapters will be added as and when a need for them is recognized.
The presentation of photometric data for luminaires is under consideration by the International Commission on Illumination (CIE) and is not, therefore, included in this part.
Requirements are included in this part for luminaires incorporating ignitors with nominal peak values of the voltage pulse not exceeding those of Table 11.2. The requirements apply to luminaires with ignitors built into ballasts and to luminaires with ignitors separate from ballasts. For luminaires with ignitors built into lamps, the requirements are under consideration.
Requirements for semi-luminaires are included in this part.
In general, this part covers safety requirements for luminaires. The object of this part is to provide a set of requirements and tests which are considered to be generally applicable to most types of luminaires and which can be called up as required by the detail specifications of GB 7000.2. This part is thus not regarded as a specification in itself for any type of luminaire, and its provisions apply only to particular types of luminaires to the extent determined by the appropriate part of GB 7000.
Part 2 of GB 7000, in making reference to any of the chapters of this part, specify the extent to which that chapter is applicable and the order in which the tests are to be performed; they also include additional requirements as necessary.
The order in which the chapters of this part are numbered has no particular significance as the order in which their provisions apply is determined for each type of luminaire or group of luminaires by the appropriate part of GB 7000.2. All parts of GB 7000.2 are self-contained and therefore do not contain references to other parts of GB 7000.2.
Where the requirements of any of the chapters of this part are referred to in the parts of GB 7000.2 by the phrase "The requirements of chapter... of GB 7000.1 apply", this phrase is to be interpreted as meaning that all the requirements of that chapter of this part apply except those which are clearly inapplicable to the particular type of luminaire covered by that part of GB 7000.2.
For explosion proof luminaires, as covered by IEC 60079, the requirements of GB 7000 (selecting the appropriate parts in GB 7000.2) are applied in addition to the requirements of IEC 60079. In the event of any conflict between GB 7000 and IEC 60079, the requirements of IEC 60079 take priority.
Attention is drawn to lamp performance standards which contain “information for luminaire design”; this should be followed for proper lamp operation; however, this part does not require the testing of lamp performance as part of the type test approval for luminaires.
Improvements in safety to take into account the state of the art technology are incorporated in the standards with revisions and amendments on an ongoing basis. Regional standardization bodies may include statements in their derived standards to cover products which have complied with the previous document as shown by the manufacturer or standardization body. The statements may require that for such products, the previous standard may continue to apply to production until a defined date after which the new standard shall apply.
