Internal resistance

4.4.3

See IEC 62391-1, 4.6.2, with the following details.

NOTE The a.c. resistance method should be used when a correlation is found with the results of the d.c. measuring method. The measuring method should be in accordance with IEC 62391-1, 4.6.1.

4.4.3.1 Measuring conditions

The ambient temperature shall be 20 °C ± 2 °C.

The measurement shall be made under the conditions of IEC 62391-1, 4.6.2.1, Class 3.

Robustness of terminations

4.5

See IEC 62391-1, 4.9, with the following details.
