Solderless connections - Part 7: Spring clamp connections - General requirements, test methods and practical guidance
Scope:
This part of IEC 60352 is applicable to spring clamp connections made with stripped wire of the following types and sizes according to IEC 60228:2023 or IEC 60189-3, without further preparation (later described “unprepared”):
– solid conductors (e.g. class 1 of IEC 60228:2023) of 0,32 mm to 3,7 mm nominal diameter (0,08 mm2 to 10 mm2 cross-section), or
– stranded conductors (e.g. class 2 of IEC 60228:2023) of 0,08 mm2 to 10 mm2 cross-section,
or
– flexible conductors (e.g. class 5 or 6 of IEC 60228:2023) of 0,08 mm2 to 10 mm2 cross-section, for use in electrical and electronic equipment and components.
Information on materials and data from industrial experience is included in addition to the test procedures to provide electrically stable connections under prescribed environmental conditions.
The object of this document is to determine the suitability of spring clamp connections under specified mechanical, electrical and atmospheric conditions.
NOTE IEC Guide 109 advocates the need to minimize the impact of a product on the natural environment throughout the product life cycle. It is understood that some of the materials permitted in this document may have a negative environmental impact. As technological advances lead to acceptable alternatives for these materials, they will be eliminated from this document.

Shunt power capacitors of the non-self-healing type for AC systems having a rated voltage up to and including 1000 v - Part 1: General
Scope:
This part of IEC 60931 is applicable to both capacitor units and capacitor banks intended to be used, particularly, for power-factor correction of AC power systems having a rated voltage up to and including 1000 V and frequencies 15 Hz to 60 Hz.
This part of IEC 60931 also applies to capacitors intended for use in power filter circuits. Additional definitions, requirements, and tests for filter capacitors are given in annex A.
The following capacitors are excluded from this part of IEC 60931:
– Shunt power capacitors of the self-healing type for AC systems having a rated voltage up to and including 1000 V (IEC 60831 series).
– Shunt capacitors for AC power systems having a rated voltage above 1000 V (IEC 60871).
– Power Capacitors for induction heating installations (IEC 60110 series).
– Series capacitors for power systems (IEC 60143 series).
– Capacitors for motor applications (IEC 60252 series).
– Coupling capacitors and capacitor dividers (IEC 60358).
– Capacitors for power electronics (IEC 61071).
– Small AC capacitors to be used for fluorescent and discharge lamps (IEC 61048 and IEC 61049).
– Capacitors for suppression of radio interference (under consideration).
– Capacitors intended to be used in various types of electrical equipment and thus considered as components.
– Capacitors intended for use with DC voltage superimposed on the AC voltage.
– Shunt power capacitors of the self-healing type for AC systems having a rated voltage above 1000V (IEC 63210).
Accessories such as insulators, switches, instrument transformers, fuses, etc., are to be in accordance with the relevant IEC standards.
The purpose of this part of the IEC 60931 standard is:
a) to formulate uniform rules regarding performances, testing and rating;
b) to formulate specific safety rules;
c) to provide a guide for installation and operation.
