AS NZS 62838:2020 – LEDsi lamps for general lighting serviceswith supply voltages not exceeding 5o va.c. r.m.s.or 120 V ripple free d.c.一Safety specifications (IEC 62838:2015(ED.1.0)/COR1:2017,MOD).
The value of the lamp mass shall not exceed the relevant value of Table 1. Compliance shall be checked by measurement.
7 Protection against accidental contact with live parts
Lamps which are intended for ELV installations as specified in the scope may have accessible conductive parts, but where voltage exceeds 25 V a.c. r.m.s. or 60 V d.c. ripple tree, the touch current shall not exceed:
– to.’ a.c.: 0.7 mA (peak)
— to. d.c.: 2,0 mA.
The limits given are based on IEC 60364-4-41
The external metal parts other than current-carrying metal parts of the cap of all lamps shall not be or become live. For testing. any movable conductive material shall be placed in the most onerous position without using a tool,
Compliance is checked by the touch current requirements of IEC 60598-1, Section 8 and Annex G.
8 Insulation resistance and electric strength after humidity treatment
8.1 General
Insulation resistance and electric strength shall be adequate between live parts of the lamp and accessible parts of the lamp.
8.2 Insulation resistance
The lamp shall be conditioned for 48 h In a cabinet containing air with a relative humidity between 91 % and 95 %. The temperature of the air is maintained within 1 C of any convenient value between 20 C and 30 C.
Insulation resistance shall be measured in the humidity cabinet with a dc, voltage of approximately 500 V. 1 mm after application of the voltage.
The insulation resistance between live parts of the cap and accessible parts of the lamp
(accessible parts of insulating material are covered with metal foil) shall be not less than
1 Mn.
8.3 Electric strength
Immediately after the insulation resistance test, the same parts as specified above shall withstand a voltage test for I mm with an ac. 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.
No flashover or breakdown shall occur during the test. Measurements shall be carried out In the humidity cabinet.
NOTE I The distance between the Lou and the parts is under cOnsideration
16 Photoblological safety
16.1 UV radiation
The ultraviolet hazard efficacy of luminous radiation of a LED lamp shall not exceed 2 mW/kim.
Compliance is checked by measurement of the spectral power distribution and subsequent calculation of the ultraviolet hazard efficacy of luminous radiation.
LED lamps not relying on the conversion of UV radiation are not expected to exceed the maximum allowed ultraviolet hazard efficacy of luminous radiation They do not require measurement.
16.2 Blue light hazard
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 WI(m2 x sr) is not exceeded.

16.3 Infrared radiation
LED lamps are not expected to reach a level of infrared radiation where marking or other
safety measures are required. They do not require measurement.
17 Ingress protection
17.1 Lamps shall be suitable for water contact unless marked with Figure 2.
17.2 Suitability for water contact is tested as follows.
The lamp is subjected to an IPX4 test according to IEC 60598.1 During this test. lampholders sealing to the diameter of the lamp ends and providing protection to the contact area of IPX4 shall be fitted.
The compliance provisions of IEC 60598-1, 9.2 apply.
NOTE For moe. intorrnat,on about ingress pto1ectlon (iP, see IEC 60598-I. Annex J.
17.3 A lamp constructed so that it is sealed (e.g. lamp designs having one piece homogeneous glass or plastic bulb penetrating the lampholder sealing) to exclude water need not be subjected to this test.
