IEC/IEEE 62582-3:2024 contains methods for condition monitoring of organic and polymeric materials in instrumentation and control systems using tensile elongation techniques in the detail necessary to produce accurate and reproducible measurements. This document includes the requirements for the selection of samples, the measurement system and conditions, and the reporting of the measurement…
Anaesthetic and respiratory equipment – Anaesthetic reservoir bags
This document specifies requirements for anaesthetic reservoir bags for use with anaesthetic and ventilator breathing systems. It includes requirements for the design of the neck, size designation and elasticity.
This document is not applicable to special-purpose bags, for example bellows, self-inflating bags and bags for use with anaesthetic gas scavenging systems.
The requirements in this…
Anaesthetic and respiratory equipment — Respiratory therapy tubing and connectors
This document specifies requirements for the respiratory tubing and connectors used to convey respirable gases to a patient in the healthcare and homecare environments and provide a safe connection between the gas supply device and the patient interface. Respiratory tubing and connectors are mainly used for delivery of oxygen but can also be used for respirable air or oxygen/air mixtures and…

IEC 61000-2-4:2024 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 61000-2-4:2024 is related to conducted disturbances in the frequency range from 0 kHz to 150 kHz. It gives…
Measurement of DC magnetic, AC magnetic and AC electric fields from 1 Hz to 100 kHz with regard to e...
IEC 61786-1:2013+AMD1:2024 CSV provides guidance for measuring instruments used to measure the field strength of quasi-static magnetic and electric fields that have a frequency content in the range 1 Hz to 100 kHz and with DC magnetic fields to evaluate the exposure levels of the human body to these fields. Sources of fields include devices that operate at power frequencies and produce power…
Protective clothing — Test methods for clothing providing protection against chemicals — Part 5: Det...
This document specifies a test method for determining the resistance of complete protective clothing to inward leakage of liquid chemicals (protective clothing integrity).
This method specifies an alternative method for determining the resistance to spray penetration because it uses a static manikin instead of a test subject; it also uses a different spray configuration and duration than the…
Information technology — Coded representation of immersive media — Part 3: Versatile video coding
This document specifies a video coding technology known as versatile video coding (VVC), comprising a video coding technology with a compression capability that is substantially beyond that of the prior generations of such standards and with sufficient versatility for effective use in a broad range of applications.
Only the syntax format, semantics, and associated decoding process requirements…
