Development methodologies may be described in the context of an underpinning metamodel, but the precise mechanisms that permit them to be defined in terms of their metamodels are usually difficult to explain and do not cover all needs. For example, it is difficult to devise a practice that allows the definition of properties of the elements that compose the methodology and, at the same time, of…

ISO 14813-1:2007 provides a definition of the primary services and application areas that can be provided to Intelligent Transport System (ITS) Users. Those with a common purpose can be collected together in ITS service domains, and within these there can be a number of ITS service groups for particular parts of the domain. ISO 14813-1:2007 identifies 11 service domains, within which numerous…

This part of IEC 61482 specifies methods to test material and garments intended for use in heat- and flame-resistant clothing for workers exposed to electric arcs. In contrast to the test methods in IEC 61482-1-1 a directed and constrained electric arc in a low voltage circuit is used to classify material and clothing in defined arc protection classes. The test methods specified in this document…

This part of IEC 60079 specifies general and testing requirements for electrical resistance trace heaters for application in explosive gas atmospheres. The standard covers trace heaters that may comprise either factory- or field- (work-site) assembled units, and which may be series heating cables, parallel heating cables or heating pads and heating panels that have been assembled and/or…

1 Scope 1.1 This Standard sets forth methods for both new installation and replacement installation of factoryassembled windows, exterior doors, and unit skylights that are intended for installation in low-rise buildings and buildings used primarily for residential occupancy where (a) the windows (including window wall) are (i) within the application of CAN/CSA-A440/A440.1; or (ii) R, LC,…

1.1 These requirements cover hose in nominal internal diameter sizes of 8 mm up to and including 32 mm for use on portable and wheeled fire extinguishers, hand hose line fixed extinguishing systems, and also as booster hose on fire apparatus. 1.2 Fire extinguisher, hand hose line system and booster hose covered by these requirements is intended for use at a maximum working pressure of 1400,…

This Standard covers barrel-type hydrants with compression shut-off and slide gate shut-off, for general water works service. This Standard does not cover wet barrel type hydrants. References to the setting and drainage of hydrants are not included in this Standard.

1.1 This Standard sets forth minimum requirements for hose and hose assemblies, including vapour recovery hose and assemblies, for use on dispensing devices for flammable and combustible liquids. For the purpose of this Standard flammable and combustible liquids mean gasoline, fuel oil, kerosene and diesel fuel, including gasoline with small amounts of additives such as detergents, solvents for…

Cover hose nozzle valves that are intended to be used to control the flow of flammable and combustible liquids. They are of the types used in the assembly of motor fuel dispensing equipment. Valves covered by this Standard are for use with flammable and combustible liquids which are handled at temperatures within the range of -40°C to + 50°C at a working pressure of not less than 350 kPa. For the…

This National Standard of Canada is equivalent to International Standard ISO/IEC 19501:2005. 1 Scope This standard specifies the Unified Modeling Language (UML) with the objective of providing system architects working on object analysis and design with one consistent language for specifying, visualizing, constructing, and documenting the artifacts of software systems, as well as for…
