ISO/IEC 18012-3:2025 specifies a lexicon of objects for the interoperability domain (ID). This document specifies ID base objects and their associated properties and input/output event types (i.e. in the form of a list of ID sensor, actuator, and control objects), and object state actions, which can be used to define interoperable application models.
Information technology - Spatial reference model (SRM)
This document specifies the Spatial Reference Model (SRM) defining relevant aspects of spatial positioning and related information processing. The SRM allows precise and unambiguous specification of geometric properties such as position, direction, orientation, and distance. The SRM addresses the needs of a broad community of users, who have a range of accuracy and performance requirements in…

ISO/IEC 18012-4:2025 specifies an event exchange format that defines the encoding of individual events in the interoperability domain. This event format is used to encode events for exchange across the “event bus” within the interoperability domain.
Refrigerated hydrocarbon and non-petroleum based liquefied gaseous fuels — Metering of gas as fuel o...
This document specifies the minimum requirements to quantify boil-off gas (BOG) consumed on liquefied natural gas (LNG) carriers for their own functions, in particular for power generation and during cargo transfer operations.
This document provides requirements for the metering of BOG and the subsequent calorific value calculations, which can be taken into account when the energy transferred…
Graphic technology and photography — Viewing conditions
This document specifies viewing conditions for images on both reflective and transmissive media, such as prints (both photographic and photomechanical) and transparencies.
This document applies to
— critical evaluation of and comparison between transparencies, backlighted signs, reflection photographic or photomechanical prints and/or a reference object or image,
— appraisal of the tone…
Mesurage de la radioactivité — Détermination de l’activité des radionucléides émetteurs bêta — Métho...
Le présent document s’applique à la détermination de l’activité volumique des émetteurs bêta par comptage des scintillations en milieu liquide. La méthode requiert la préparation d’une source scintillante, obtenue en mélangeant la prise d’essai et un cocktail scintillant. La prise d’essai peut être liquide (aqueuse ou organique) ou solide (particules, filtre ou coupelle).
NOTE Ces…
