Active assisted living (AAL) reference architecture and architecture model - Part 2: Architecture mo...
IEC 63240-2:2020 specifies the AAL architecture model.
This document defines concepts and introduces terminology. IEC 63240-1 provides generic rules for designers of AAL systems and services with the aim to facilitate systems design and enable interoperability between components. This document provides a framework to analyse use cases on a common view and terminology, which is a foundation for…
Indoor air — Part 28: Determination of odour emissions from building products using test chambers
This document specifies a laboratory test method using test chambers defined in ISO 16000-9 and further specified in EN 16516 and evaluation procedures for the determination of odours emitted from building products and materials.
Sampling, transport and storage of materials under test, as well as preparation of test specimens are described in ISO 16000-11 and further specified in EN 16516.
Test code for machine tools — Part 3: Determination of thermal effects
This document defines four tests:
— an environmental temperature variation error (ETVE) test;
— a test for thermal distortion caused by rotating spindles;
— a test for thermal distortion caused by moving linear axes;
— a test for thermal distortion caused by rotary motion of components.
The tests for thermal distortion caused by moving linear axes (see Clause 7…
Road vehicles — Compressed natural gas (CNG) fuel system components — Part 4: Manual valve

Residual current operated circuit-breakers for household and similar use - Part 1: Outline of blocks...
IEC 62873-1:2017+A1:2020. The IEC 62873 series covers available common standards intended to be used in conjunction with or for the preparation of RCD (residual current device) standards. This part of IEC 62873 defines the methodology and processes used when producing standards based on a new approach (hereafter referred to as blocks and modules) aiming at harmonizing a family of standards, thus…
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…

Small craft — Hull construction and scantlings — Part 10: Rig loads and rig attachment in sailing cr...
This document specifies methods for the determination of:
— the design loads and design stresses on rig elements; and
— the loads and scantlings of rig attachments and mast steps/pillars;
on monohull and multihulls sailing craft.
It also gives, in Annexes, "established practices" for the assessment of mast steps/pillars or chainplates
