IEC 62899-302-6:2025 specifies the method for determining inkjet first drop behaviour based on either visualized droplet images or printed dots on standard substrate. The exact behaviour that is referenced in this document is as follows: jetting speed variation according to the drop numbers, including non-jetting and low jetting speed. This measurement standardization is limited to drop-on-demand…

IEC 62341-6-1:2025 specifies the standard measurement conditions and measuring methods for determining the optical and electro-optical parameters of organic light emitting diode (OLED) displays. Except for the power consumption method, all methods are intended for unbounded input signals measured in the flat regions of the display in a dark room. This fourth edition cancels and replaces the third…

IEC TR 63534:2025 reviews existing theoretical attempts and engineering applications in the area of solar PV systems coupled to LVDC systems. There are three aspects that are identified to be highly relevant to standard compilations: power converters and possible control mechanisms that are eligible for facilitating the interlinking between PV and LVDC networks; local PV system islanding…

IEC 63378-3:2025 specifies the thermal circuit network model of discrete (TO‑243, TO‑252 and TO‑263) packages, which is used in the transient analysis of electronic devices to estimate precise junction temperatures without experimental verification. This model is intended to be made and provided by semiconductor suppliers and to be used by assembly makers of electronic devices.

The database has been updated following the publication of Amendment 64 to Part 1 and Amendment 60 to Part 2. It contains the recommendations of the IEC in regard to lamp caps and holders in general use, together with relevant gauges, with the object of securing international interchangeability. The standard consists of four parts. Part 1: Lamp caps, Part 2: Lampholders, Part 3: Gauges, Part 4…
