L'IEC 61000-3-12:2011 traite de la limitation des courants harmoniques injectés dans le réseau public d'alimentation. Les limites définies dans la présente Norme internationale sont applicables aux appareils électriques et électroniques ayant un courant assigné d'entrée strictement supérieur à 16 A et inférieur ou égal à 75 A par phase, destinés à être connectés aux réseaux publics…
Gas cylinders — Specifications and testing of LPG cylinder valves — Self-closing
This document specifies the requirements for design, specification, type testing and production testing and inspection for dedicated LPG self-closing cylinder valves for use with and directly connected to transportable refillable LPG cylinders.
It also includes requirements for associated equipment for vapour and liquid service. Bursting discs and/or fusible plugs are not covered in this document…
Aerospace — Couplings, threaded and sealed, for fluid systems — Dimensions
This document establishes a system for sealing the port connection of couplings used in the aerospace industry.
It specifies dimensions to achieve interchangeability of the port connection, the fitting end and a seal. The seal can be a standard O‑ring or a special ring.
Aerospace — Fluid systems — Interface of 24° cone metric couplings
This document defines the geometry of the interface of removable 24° cone couplings for fluid systems in aircraft. The connection with the pipe of each one of the connecting elements can be of different design.
This document specifies the dimensions which allow the interchangeability of the male and female elements and of the nut used for the connection.
The dimensions define the maximum volume…
Plugs, socket-outlets and couplers with arcuate contacts
1 Scope
This document sets the general and dimensional interchangeability requirements for plugs,
socket-outlets, connectors and appliance inlets with arcuate contacts of standardized
configurations (hereinafter referred to as accessories), with a rated operating voltage not
exceeding 600 V AC at a frequency of 50 Hz and 60 Hz and with rated currents of 20 A and
30 A, primarily intended for…
1 Scope
1.1 The requirements of this Standard apply to Grades A and B acrylic-polymer-coated, siliconepolymer-
coated, or vinyl-polymer-coated electrical sleeving that consists of closely woven fabric made
from glass (see Table 1 for materials and ratings) and intended for use in equipment designed to be
installed and used in accordance with the rules of CSA C22.1, Canadian Electrical Code,…
Identification cards - Transport layer topologies - Configuration for HCI/HCP interchange
This document specifies the requirements for a protocol derived from HCI/HCP (see ETSI TS 102 622) enabling communication for devices regardless of data link and physical layers. This document covers the following:
a) outline of a system comprised of one or more hosts and one controller;
b) extension of connection topology between hosts and host controller (i.e. star topology and additional…
