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…
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…

Measurement of radioactivity — Determination of beta emitters activities — Test method using liquid ...
This document applies to the determination of beta emitters activity concentration using liquid scintillation counting. The method requires the preparation of a scintillation source, which is obtained by mixing the test sample and a scintillation cocktail. The test sample can be liquid (aqueous or organic), or solid (particles or filter or planchet).
NOTE Planchet are samples,…
