AS NZS 4782.1:2020 pdf free.Double-capped fluorescent lamps – Performance specifications Part 1: General (IEC 60081:1997+AMD1:2000 CSV (ED.5.1), MOD).
1.5.2 Caps
The dimensions of the caps on a finished lamp shall be in accordance with IEC 60061-1.
For lamps with G5 or G13 caps, both pins (excluding flanges) of the two caps of a finished lamp shall pass simultaneously, freely without binding, through parallel slots, suitably spaced longitudinally to receive the lamp. The slots shall each be 2,87 mm wide for G5 caps, and 3,05 mm wide for G13 caps.
For lamps with R17d caps, both cap bosses of a finished lamp shall pass simultaneously, freely without binding, through parallel slots, suitably spaced longitudinally to receive the lamp with the bottom of the slots against the boss ends. The slots shall each be 6,35 mm deep and 9,22 mm wide.
1.5.3 Dimensions
The dimensions of a lamp shall comply with the values specified on the relevant lamp data sheet.
1.5.4 Starting characteristics
A lamp shall start fully within the time specified on the relevant lamp data sheet and remain alight.
Conditions and method of test are given in Annex A.
1.5.5 Electrical and cathode characteristics
Lamps shall comply with the following requirements:
a) The initial reading of the voltage at the lamp terminals shall comply with the values specified on the relevant lamp data sheet.
NOTE 1 It may be expected that over the declared lifetime of the lamp, the lamp voltage may rise typically by 5 V to 10 V.
b) The initial reading of the power dissipated by a lamp shall not exceed the rated wattage, specified on the relevant lamp data sheet, by more than 5 % + 0,5 W.
NOTE 2 Cathode watts due to supplementary heating are not included in the rated lamp wattage unless otherwise stated on the lamp data sheet.
c) The combined resistance of the lead wires connected to an individual cathode for a lamp without internal starter shall not be higher than 0,3 2.
d) For a lamp having preheated cathodes for operation on a.c. mains frequencies starterless circuits, the initial reading of the resistance of each cathode shall be not less than the minimum value specified on the relevant lamp data sheet. These resistance values include lead wire resistance.
e) For a lamp having preheated cathodes for operation on high frequency, the initial reading of the resistance of each cathode shall comply with the values specified on the relevant lamp data sheet. These resistance values include lead wire resistance.
In addition, the average value of the resistance ratio Rh/Rc of the coils of 10 cathodes shall be in the range 4,75 ± 0,5. Rh is the resistance of the cathode when heated with the specified test current. Rc is the resistance of the cathode at a temperature of 25 °C ± 1 °C. Both resistance values shall exclude lead wire resistance. Conditions and method of test are given in Annex B. AS NZS 4782.1 pdf download.
