Luminaires Part 1: General requirements and tests
0 General introduction
0:1 Scope
This document specifies the general requirements for lamps using electric light sources with a supply voltage not exceeding 1000V: The requirements set out in this document and related
Relevant tests include: classification, marking, mechanical structure, electrical structure and photobiological safety:
Each chapter of this document should be read in conjunction with Chapter 0 and other relevant chapters cited:
Each part of GB/T 7000 Part 2 details a specific type of luminaire or group of luminaires with a supply voltage not exceeding 1000V
specific requirements: To facilitate revision, these parts are published separately, and when necessary, additional parts are added:
The expression of photometric data of luminaires is proposed by the International Commission on Illumination (CIE) and is therefore not covered in this document:
This document contains requirements for luminaires with triggers whose nominal pulse voltage peak does not exceed the values in Table 11:2: These requirements apply
Luminaires in which the trigger is installed in the ballast and lamps in which the trigger is separate from the ballast: The requirements for lamps with triggers installed inside the lamp are under consideration
in consideration:
This document contains requirements for semi-luminaires:
In general, this document covers the safety requirements for luminaires: The purpose of this document is to provide a set of requirements applicable to most types of luminaires
and testing, and is cited by the specific provisions of GB/T 7000 Part 2: Therefore, this document should not be considered in itself as a guide for any type of luminaire:
According to the regulations, the terms of this document only apply to specific types of lamps within the scope determined in Part 2 of GB/T 7000:
When Part 2 of GB/T 7000 cites the chapter requirements of this document, it stipulates the degree of applicability of the chapter, the test sequence, and, if necessary, the
some additional requirements:
The chapter numbers in this document have no special meaning: The order of applicable clauses for each type of lamp or group of lamps is determined by the corresponding GB/T
7000 Part 2 Regulations: All parts of GB/T 7000 Part 2 are independent and do not reference GB/T 7000 Part 2
other parts of:
When GB/T 7000 Part 2 is preceded by “applying the provisions of Chapter 1 of Part 1” (or “applying the provisions of Chapter GB/T 7000:1
When the requirements of any chapter of this document are quoted in the wording ""), the meaning of this sentence is to be interpreted as: in addition to the special requirements involved in GB/T 7000 Part 2
All requirements in this chapter of this document are applicable except those that are obviously not applicable to certain types of lamps:
