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). This standard does not…

1 Scope This clause of Part 1 is replaced by the following. This International Standard deals with the safety of electric pumps for liquids having a temperature not exceeding 90 °C, intended for household and similar purposes, their rated voltage being not more than 250 V for single-phase appliances and 480 V for other appliances. NOTE 101 This Standard covers both permanently…

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…
