Small medical gas cylinders — Pin-index yoke-type valve connections
This document is applicable to pin-index yoke-type valve connections for medical gas cylinders, with a working pressure up to a maximum of 200 bar or test pressure up to a maximum of 300 bar, or both.
NOTE 1 This type of connection is primarily used for small cylinders (5 l or below).
NOTE 2 In this document the unit bar is used, due to its universal use in the field of technical gases. It…
Electromagnetic compatibility (EMC) - Part 3-12: Limits - Limits for harmonic currents produced by e...
IEC 61000-3-12:2011+A1:2021 deals with the limitation of harmonic currents injected into the public supply system. The limits given in this International Standard are applicable to electrical and electronic equipment with a rated input current exceeding 16 A and up to and including 75 A per phase, intended to be connected to public low-voltage a.c. distribution systems of the following types:
-…

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…
