High-voltage switchgear and controlgear - Part 107: Alternating current fused circuit-switchers for ...
IEC 62271-107:2019 RLV contains both the official IEC International Standard and its Redline version. The Redline version is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its previous edition.
IEC 62271-107:2019 applies to three-pole-operated fused circuit-switchers designed with rated voltages above 1 kV…
devices and immersion suits. Compliance with these requirements does not indicate that the product is
intended for use as a component of an end product without further investigation. The requirements shall
be applied to other components if found to be appropriate.
1.2 The components addressed in this Standard are intended for use in personal flotation devices and
immersion suits which comply…
Information technology — Generic coding of moving pictures and associated audio information — Part 1...
This Recommendation | International Standard specifies the system layer of the coding. It was developed principally to support the combination of the video and audio coding methods defined in Parts 2 and 3 of ISO/IEC 13818. The system layer supports six basic functions:
1) the synchronization of multiple compressed streams on decoding;
2) the interleaving of multiple compressed streams into…

This document specifies the coexistence mechanism for various broadband powerline communication systems. By using the coexistence mechanism, possible harmful interference between different standard-based high-speed powerline communication systems can be avoided.
Alarm systems - Part 7-8: Message formats and protocols for serial data interfaces in alarm transmis...
IEC 60839-7-8:2019 specifies a protocol for point-to-point transmission of alarms and faults, as well as communications monitoring, between a supervised premises transceiver and a receiving centre transceiver using the Internet protocol (IP).
The protocol is intended for use over any network that supports the transmission of IP data. These include Ethernet, xDSL, GPRS, WiFi, UMTS and WIMAX.
