Medical electrical equipment — Part 2-70: Particular requirements for the basic safety and essential...
This document is applicable to the basic safety and essential performance of sleep apnoea breathing therapy equipment, hereafter referred to as ME equipment, intended to alleviate the symptoms of patients who suffer from obstructive sleep apnoea by delivering a therapeutic breathing pressure to the respiratory tract of the patient. Sleep apnoea breathing therapy equipment is intended for use in…
Information security — Key management — Part 5: Group key management
This document specifies mechanisms to establish shared symmetric keys between groups of entities. It defines:
— symmetric key-based key establishment mechanisms for multiple entities with a key distribution centre (KDC); and
— symmetric key establishment mechanisms based on a general tree-based logical key structure with both individual rekeying and batch rekeying.
It also defines key…

Earth-moving machinery — Hydraulic breakers — Terminology and commercial specifications
This document establishes the terminology and content of commercial specifications for hydraulic breakers which are mounted as an attachment on a carrier, typically earth-moving machinery such as an excavator, backhoe loader, skid steer loader, and compact loader as defined in ISO 6165; or mounted on a rig, pedestal boom system, demolition robot, etc., at the end of an arm.
Hydraulic breakers are…
Information container for linked document delivery — Exchange specification — Part 2: Link types
This document provides the opportunity to add information about the contents of a container by further specializing the generic types of links specified in ISO 21597-1. The defined link types have been chosen to enhance the use of the container by allowing the addition of semantic relationships that are human interpretable to provide greater clarity about those links.
This document specifies a molecular absorption spectrophotometric method for the determination of titanium content in nickel alloys.
The method is applicable to titanium contents between 0,3 % (mass fraction) and 5,0 % (mass fraction).
Molybdenum, if present in the alloy, can cause a high bias in the reported titanium value to the extent of 0,001 % Ti for every 1,0 % Mo.

Information technology — Coding of audio-visual objects — Part 3: Audio
1 Scope
This document integrates many different types of audio coding: natural sound with synthetic sound, low bitrate
delivery with high-quality delivery, speech with music, complex soundtracks with simple ones, and traditional
content with interactive and virtual-reality content. This document standardizes individually sophisticated
coding tools to provide a novel, flexible framework for…
Information technology — Multimedia application format (MPEG-A) — Part 19: Common media application ...
1 Scope
This document specifies the CMAF multimedia format, which contains segmented media objects optimized for streaming delivery and decoding on end user devices in adaptive multimedia presentations.
CMAF specifies a track format derived from the ISO base media file format, then derives addressable media objects from CMAF tracks that can be used for storage and delivery.
CMAF specifies sets…
