LUMINAIRES –
Part 2-24: Particular requirements –
Luminaires with limited surface temperatures


24.1 Scope

This part of the IEC 60598 series specifies requirements for luminaires intended for use where the necessity of limited temperature on the outer surface exists, due to the risk of thermal effects, combustion or degradation of materials but where the risk of explosion in the atmosphere does not exist. The luminaires are for use with electric light sources on supply voltages not exceeding 1 000 V.

This standard specifically excludes requirements for luminaires for use in explosive gas atmospheres and explosive dust atmospheres.

24.2 Normative references

The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

IEC 60364-4-42, Low-voltage electrical installations – Part 4-42: Protection for safety – Protection against thermal effects

IEC 60598-1, Luminaires – Part 1: General requirements and test

ISO 4225:1994, Air quality – General aspects – Vocabulary

24.3 General test requirement

The provisions of Section 0 in IEC 60598-1 apply. The tests described in each appropriate section of IEC 60598-1 shall be carried out in the order listed in this standard.

24.4 Terms and definitions

For the purposes of this document, the terms and definitions given in Section 1 of IEC 60598-1 apply, as well as the following apply.

24.4.1
dust
small solid particles in the atmosphere which settle out under their own weight, but which may remain suspended in air for some time (includes dust and grit as defined in ISO 4225) 

24.4.2
explosive gas atmosphere

mixture with air, under atmospheric conditions, of flammable substances in the form of gas or vapour which, after ignition, permits self sustaining flame propagation

[SOURCE: IEC 60050-426:2008, 426-01-07]

24.4.3
explosive dust atmosphere
a mixture with air, under atmospheric conditions, of flammable substances in the form of dust,
fibres or flyings which, after ignition, permits self-sustaining propagation
[SOURCE: IEC 60050-426:2008, 426-01-08]

24.5 Classification of luminaires

Luminaires shall be classified in accordance with the provisions of Section 2 of IEC 60598-1. Additionally luminaires complying with this section are classified suitable for use in locations specified in IEC 60364-4-42 as follows.

a) For use in environments where no unusual accumulation of dust is expected.

b) For use in environments where an accumulation of non-conductive dust on the luminaire
may be expected.

c) For use in environments where an accumulation of conductive dust on the luminaire may be expected.

24.6 Marking

The provisions of Section 3 of IEC 60598-1 apply together with the following requirements.

24.6.1 Luminaires shall be marked with the symbol (see Figure 1). This marking shall be visible and meet the requirements of 3.2 c) of IEC 60598-1.

Figure 1 – Symbol for luminaires with limited surface temperatures

24.6.2 From the manufacturers literature it shall be evident to which location the luminaire is intended in accordance with the luminaires classification as given in 24.5 of this standard.

24.7 Construction

The provisions of Section 4 of IEC 60598-1 apply, together with the requirements of 24.7.1 and 24.7.2 below.

24.7.1 Luminaires shall be provided with an enclosure providing a degree of protection of at least IP4X or in the presence of dust, IP5X or in the presence of conductive dust, IP6X.

For certain locations the international wiring rules may require at least IP5X or IP6X (see  IEC 60364-4-42).

Compliance is checked by inspection.
