Il s'agit de fournir des mesures normalisées pouvant être utilisées pour créer et organiser des méthodes de calcul et de déclaration de la disponibilité en fonction des besoins de l'utilisateur. Le…

This document defines a reference model and base components for representing and controlling a single LAE or multiple LAEs in an MAR scene. It defines concepts, a reference model, system framework, functions and how to integrate a 2D/3D virtual world and LAEs, and their interfaces, in order to provide MAR applications with interfaces of LAEs. It also defines an exchange format necessary for…

This document specifies performance requirements, methods of test and marking requirements for pre-action dry alarm valves, valve sets and manufacturers' specified relevant trim used in non-interlock pre-action automatic fire protection systems. Performance and test requirements for other auxiliary components or attachments to pre-action dry valves are not covered by this document.

This document lists the different valve stem to gas cylinder connection threads currently and historically existing worldwide and provides official coded designations for them. These coded designations will then be available for identification and marking purposes. It also gives guidance concerning which threads are dimensionally identical and which are interchangeable. Furthermore, this document…
