Requirement
The voltage between two terminals with To meet the specified value
the specified measuring current applied
is called V_V (1 mA_DC @ 0.2 ... 2 s).
The maximum voltage between two To meet the specified value
terminals with the specified standard
impulse current (8/20 µs) applied.
1000 h at UCT
|∆V/V (1 mA)| ≤10%
After having continuously applied the
maximum allowable AC voltage at UCT
±2 °C for 1000 h, the specimen shall be
stored at room temperature and normal
humidity for 1 to 2 h.
Thereafter, the change of V_V shall be
measured.
10 surge currents (8/20 µs), unipolar, |∆V/V (1 mA)| ≤10%
interval 30 s, amplitude corresponding (measured in direction of
to derating curve for 10 impulses at
20 µs
surge current)
No visible damage
10 surge currents (2 ms), unipolar,
|∆V/V (1 mA)| ≤10%
interval 120 s, amplitude corresponding _{(measured in direction of}
to derating curve for 10 impulses at
surge current)
2 ms
No visible damage
IEC 61051-1, test 4.9.2
No breakdown
Metal balls method, 2500 V_RMS, 60 s
The varistor is placed in a container
holding 1.6 ±0.2 mm diameter metal
balls such that only the terminations of
the varistor are protruding.
The specified voltage shall be applied
between both terminals of the specimen
connected together and the electrode
inserted between the metal balls.
