quotient of a ultraviolet hazard quantity to the corresponding photometric quantity
Note 1 to entry: Ultraviolet hazard efficacy of luminous radiation is expressed in mW/klm.
Note 2 to entry: The ultraviolet hazard efficacy of luminous radiation is obtained by weighting the spectral power distribution of the lamp with the UV hazard function Suv(X). Information about the relevant UV hazard function is given in IEC 62471. It only relates to possible hazards regarding UV exposure of human beings. It does not deal with the possible influence of optical radiation on materials, such as mechanical damage or discoloration.
Lamps with bulbs not suitable for water contact shall be marked with the symbol according to Figure 2. The marking shall be provided on the packaging or accompanying information. The height of the graphical symbol shall be at least 5 mm. The symbol is not needed if a written cautionary notice is provided.
Interchangeability shall be ensured by the use of caps in accordance with IEC 60061-1 and gauges in accordance with IEC 60061-3; see Table 1. Caps originally developed for single-capped extra low voltage (ELV) lamps shall not be used for mains voltage lamps. Examples of ELV lamp caps are given in Table 1, see also IEC 60432-3.
Immediately after the insulation resistance test, the same parts as specified above shall withstand a voltage test for 1 min with an a.c. voltage as follows.
During the test the supply contacts of the cap are short-circuited. Accessible parts of insulating material of the cap are covered with metal foil. Initially no more than half the voltage prescribed in Table 2 is applied between the contacts and the metal foil. It is then gradually raised to the full value.
The blue light hazard shall be assessed according to IEC TR 62778, which shall be regarded as normative when testing LED lamps to this standard. LED lamps shall be classified as Risk Group 0 unlimited or Risk Group 1 unlimited. For lamps with small light sources according to IEC TR 62778 the requirement can be fulfilled if a true radiance of the source (see IEC/TR 62778, 3.19) shows that the limit of 10 000 W/(m2 x sr) is not exceeded.AS NZS 62838 pdf free download.
