Overview
IEC TS 60110-2:2000 is a technical specification published by the International Electrotechnical Commission (IEC) focusing on power capacitors for induction heating installations. This document, Part 2 of the IEC 60110 series, defines essential requirements and test methods for ageing tests, destruction tests, and the disconnection of internal fuses in power capacitors compliant with IEC 60110-1. By standardizing these tests, the IEC 60110-2 ensures product reliability, safety, and consistent performance in industrial induction heating applications.
The specification is intended for manufacturers, testing laboratories, and engineers responsible for quality assurance and safety compliance of capacitors used in high-power induction heating systems. It outlines procedures to simulate capacitor durability under operational stresses and verifies that internal safety fuses disconnect appropriately to prevent damage or hazard.
