Corrosion des métaux et alliages — Corrosivité des atmosphères — Classification, détermination et es...
L'ISO 9223:2012 établit un système de classification de la corrosivité des environnements atmosphériques. Elle
définit des classes de corrosivité des environnements atmosphériques en fonction de la vitesse de corrosion d'éprouvettes de référence sur la première année,
donne des fonctions dose-réponse pour l'estimation normative de la classe de corrosivité sur la base de la perte…
Insulating materials - Industrial rigid laminated sheets based on thermosetting resins for electrica...
IEC 60893-3-3:2003+A1:2011 Gives the requirements for industrial rigid laminated sheets for electrical purposes based on melamine resins and different reinforcements. Applications and distinguishing properties are given. Materials which conform to this specification meet established levels of performance. However, the selection of a material by a user for a specific application should be based on…
Nanotechnologies — Characterization of multiwall carbon nanotube (MWCNT) samples
ISO/TR 10929:2012 identifies the basic properties of multiwall carbon nanotubes (MWCNTs) and the content of impurities, which characterize bulk samples of MWCNTs, and highlights the major measurement methods available to industry for the determination of these parameters.
ISO/TR 10929:2012 provides a sound basis for the research, development and commercialization of these materials.

ICT Greenhouse Gas Reduction Project Protocol: Quantification and Reporting Version 1
Recognizing the impact of ICT on the environment and the increasing attention being
placed on sourcing ICT with a low environmental footprint, CANARIE funded a project to
initiate a consortium of industrial and commercial enterprises, universities, and
government agencies with the common goal of reducing GHG emissions associated with
ICT services. Part of this project included the development…
Water quality — Examination and determination of colour
ISO 7887:2011 specifies four different methods, designated A to D, for the examination of colour.
The previously most employed method for assessment of water colour in water treatment plants, limnological surveys, etc. was based on the hexachloroplatinate scale. Methods C and D are harmonized with this traditional procedure.
Method A involves examination of apparent colour by visually observing a…
Systems and software engineering — Systems and software assurance — Part 3: System integrity levels
ISO/IEC 15026-3:2011 specifies the concept of integrity levels with corresponding integrity level requirements that are required to be met in order to show the achievement of the integrity level. It places requirements on and recommends methods for defining and using integrity levels and their integrity level requirements, including the assignment of integrity levels to systems, software products…

Industrial communication networks - High availability automation networks - Part 7: Ring-based Redun...
IEC 62439-7:2011 specifies a redundancy protocol that is based on a ring topology, in which the redundancy protocol is executed at the end nodes, as opposed to being built into the switches. Each node detects link failure and link establishment using media-sensing technologies, and shares the link information with the other nodes, to guarantee fast connectivity recovery times. The nodes have…
