1 Scope 1.1 These requirements cover bare and covered ferrules intended for field wiring and factory wiring for use in accordance with the National Electrical Code, NFPA 70 and Canadian Electrical Code, Part I, CSA C22.1. 1.2 This standard applies to ferrules that are intended to facilitate the connection of stranded wire on to devices, such as terminal blocks. Their purpose is to treat…

1.1 Scope [ Replace this clause with the following] This Standard applies to cast aluminium alloy enclosures pressurized with dry gases and gas mixtures (see Note 1) used in indoor or outdoor installations of high-voltage switchgear and controlgear, where the gas is used principally for its dielectric or arc-quenching properties, with rated voltages – of 1 kV and up to and including 52 kV,…

This document provides a taxonomy to classify the type of adaptivity within vehicle systems. The taxonomy includes five types ranging from no adaptation (type 0) to adaptations based on interpreted user characteristics and context data (type 4). This document provides definitions of the five types of adaptation and explains adaptation in a consistent and coherent manner. By offering definitions…
