DIN EN IEC 60384-14:2024-10

This part of IEC 60384 applies to capacitors and resistor-capacitor combinations intended to be connected to AC mains or other supply with a nominal voltage not exceeding 1 000 V AC (RMS), and with a nominal frequency not exceeding 100 Hz. This document includes also additional specific conditions and requirements for the connection to DC supplies with a rated voltage not exceeding 1 500 V DC. The principal object of this part of IEC 60384 is to prescribe preferred ratings and characteristics and to select, from IEC 60384-1, the appropriate quality assessment procedures, tests and measuring methods and to give general performance requirements for this type of capacitor. Test severities and requirements prescribed in detail specifications referring to this sectional specification are of equal or higher performance level; lower performance levels are not permitted. This document also provides a schedule of safety tests to be used by national testing stations in countries where approval by such stations is required. The overvoltage categories in combination with the AC mains voltages for the capacitors classified in this document are to be taken from IEC 60664-1. The standard differs from DIN EN 60384-14 (VDE 0565-1-1): 2014-04, DIN EN 60384-14 Corrigendum 1 (VDE 0565-1-1 Corrigendum 1):2016-11 and DIN EN 60384-14/A1 (VDE 0565-1-1/A1):2017-04 as follows: a) in the constant humidity and heat test all capacitor types are tested both with and without rated voltage; the number of samples has been increased; b) loss factor has been added to Group 0 tests, safety tests only; c) qualification approval based on safety and requirement tests has been moved from the main text to a normative annex; d) the range of rated voltages is specified instead of the precise rated voltage values; e) a normative annex for the description of capacitor designs and measurement of creepage/clearance has been added; f) the significance of mechanical failures (cracks) in component encapsulation as a safety feature is emphasized in the handling instructions and requirements after all relevant tests. Through its application, the document increases investment security for manufacturers and users, provides testing laboratories and manufacturers with defined information for testing, and increases product compatibility between manufacturers.
