applies to electrical equipment, regardless of voltage, containing an insulation system, which is - connected to an electronic power supply, and - requires an evaluation of insulation endurance under repetitive voltage impulses. This standard proposes a general test procedure to facilitate screening of electrical insulation systems (EIS) and to achieve a relative evaluation of insulation…

S'applique au matériel électrique, indépendamment de la tension, comprenant un système d'isolation - connecté à une alimentation électronique, et - nécessitant une évaluation de l'endurance de l'isolation soumise à des impulsions de tension appliquées périodiquement. Cette norme propose une procédure générale d'essai afin de faciliter la sélection des systèmes d'…

This National Standard of Canada is based on International Standard CEI/IEC 61347-1:2000 (first edition, 2000-10). 1 Scope The object of this Part 1 Standard is to specify general electrical safety requirements for certain products. The requirements of this Standard apply to a specific end-use product when it is explicitly referred to by that product standard. Each individual product…

Applies to controllers intended for starting, controlling and stopping stationary fire pumps, including automatic and non-automatic types for alternating current electric motor or diesel engine driven fire pumps. It is anticipated that a controller only controls a single driver. Controllers for electric motor driven fire pumps always include suitable short-circuit protection as an integral part…

ISO/IEC 21992:2003(E) specifies functions for using a packet network that uses the Internet Protocol (IP) as its network layer protocol and UDP and TCP as its transport layer protocols, to interconnect two Private Integrated services Network eXchanges (PINXs) forming part of a Private Integrated Services Network (PISN). Interconnection is achieved by carrying the inter-PINX signalling protocol…

1 Scope 1.1 This Standard applies to complete flue-connected, oil-fired service water heaters that are provided with automatic control devices. These service water heaters may be used both for heating and for supplying of domestic hot water. They are not to be used as sole source heating appliances. 1.2 The requirements in this Standard apply to service water heaters to be operated at…

This part of IEC 61000-4 relates to the conducted immunity requirements of electrical and electronic equipment to electromagnetic disturbances coming from intended radio-frequency (RF) transmitters in the frequency range 9 kHz up to 80 MHz. Equipment not having at least one conducting cable (such as mains supply, signal line or earth connection) which can couple the equipment to the disturbing RF…

Fieldbus is a digital serial, multidrop, data bus for communication with low-level industrial control and instrumentation devices such as transducers, actuators and local controllers. The Physical Layer provides for transparent transmission of Data Link Layer entities across physical connections. Specifies the requirements for Fieldbus component parts. Also specifies the media and network…

Gives methods of test for flexible insulating sleeving, including heat shrinkable sleeving intended primarily for insulating electrical conductors and connections of electrical apparatus. The contents of the corrigendum of December 1997 have been included in this copy. This consolidated version consists of the second edition (1997) and its amendment 1 (2003). Therefore, no need to order amendment…
