19.103 Battery chargers intended to be used with a DC distribution board are supplied at rated voltage and operated under normal operation until steady conditions are established. The load is increased to raise the output current by 10 % until steady conditions are again established. This procedure is repeated until the protective device operates or short-circuit conditions are established.
20 Stability and mechanical hazards
This clause of Part 1 is applicable.
21 Mechanical strength
This clause of Part 1 is applicable except as follows.
21.1 Modification:
The impact energy is increased to 1,0 J ± 0,05 J.
Addition:
Compliance is also checked by the test of 21.101.
21.101 Battery chargers, other than built-in battery chargers. having a mass not exceeding
5 kg are subjected to the test free-fall – procedure 1, of IEC 60068-2-3 1, which is carried out
on three appliances.
The battery chargers are dropped from a height of 1 m, each appliance being dropped from a different position.
After the test the battery chargers shall show no damage that could impair compliance with 8. 1, 15.1.1, 16.3 and Clause 29.
21.102 Battery chargers for installing in caravans and similar vehicles shall withstand vibrations to which they may be subjected.
Compliance is checked by carrying out the vibration tests specified in IEC 60068-2-6 under the following conditions:
— the battery charger is built into an enclosure made from plywood approximately 20 mm thick, the internal dimensions being the minimum stated in the installation instructions;
— the enclosure is strapped to the vibration generator with the battery charger in its normal position of use;
— the direction of vibration is vertical;
— the amplitude of vibration is 0,35 mm;
— the sweep frequency range is 10 Hz to 55 Hz;
— the duration of the test is 30 mm.
The battery charger shall show no damage that could impair compliance with 8.1, 15. 1.1, 16.3 and Clause 29, and connections shall not have worked loose.AS NZS 60335.2.29 pdf download.
