Scope

Main technical content: This standard specifies the terms and definitions of capacitors for AC motors, normal operating conditions, basic requirements, technical requirements, test methods, inspection rules, marking, packaging, transportation and storage, and quality commitments. This standard applies to motor capacitors connected to single-phase systems with a frequency of 100 Hz or lower and a rated voltage of 660 V or lower, as well as capacitors connected to three-phase asynchronous motors to enable such motors to be powered by single-phase systems (hereinafter referred to as capacitors). This document does not apply to the following capacitors: - AC motor starting capacitors (see IEC 60252-2); - Self-healing parallel capacitors for AC power systems with a nominal voltage of 1,000 V or lower (see IEC 60831-1); - Non-self-healing parallel capacitors for AC power systems with a nominal voltage of 1,000 V or lower (see IEC 60931-1); - Parallel capacitors for AC power systems with a nominal voltage above 1,000 V (see IEC 60871-1); - Capacitors for induction heating devices operating at a frequency of 50 kHz (see IEC 60110-1); - Series capacitors (see IEC 60143); - Coupling capacitors and capacitive dividers (see IEC 60358); - Capacitors for power electronics circuits (see IEC 61071); - Small AC capacitors for fluorescent lamps and discharge lamps (see IEC 61048); - Capacitors for suppressing radio interference; - Capacitors intended to be used as components in various electrical equipment; - Capacitors intended to be used under AC voltages superimposed with DC voltages.
