Vapour control systems in gasoline distribution networks
Scope
This National Standard of Canada defines equipment requirements, performance criteria, and operating and testing
procedures for the implementation of a vapour control system (VCS) in gasoline distribution networks including
terminals, bulk plants, service stations and cargo tanks, commonly known as Stage I controls (see Figure 1 for a
schematic representation).

ISO/IEC 19775 Extensible 3D (X3D) defines a software system that integrates network-enabled 3D graphics and multimedia. Conceptually, each X3D application is a 3D time-based space that contains graphic and aural objects that can be dynamically modified through a variety of mechanisms. This document defines the architecture and base components of X3D.
The semantics of X3D describe an abstract…
