law - Problems with higher temperatures
Annex F (informative) - Guide for the determination of the
voltage distribution along metal-oxide surge arresters
Annex G (normative) - Mechanical considerations
Annex H (normative) - Test procedure to determine the
lightning impulse discharge capability
Annex I (normative) - Determination of the start temperature
in tests including verification of thermal stability
