IEC 61755-2-5:2015 defines a set of prescribed conditions that should be maintained in order to satisfy the requirements of angled polished reference connections. The prescribed conditions include dimensional limits and optical fibre requirements of the optical interface to meet specific requirements for reference connection (plugs and adaptors) used for attenuation measurements. Two different…

IEC 61755-2-4:2015 defines a set of prescribed conditions that should be maintained in order to satisfy the requirements of non-angled polished reference connections. The prescribed conditions include dimensional limits and optical fibre requirements of the optical interface to meet specific requirements for reference connection (plugs and adaptors) used for attenuation measurements. Two…

This part of IEC 61980 applies to the equipment for the wireless transfer of electric power from the supply network to electric road vehicles for purposes of supplying electric energy to the RESS (Rechargeable energy storage system) and/or other on-board electrical systems in an operational state when connected to the supply network, at standard supply voltages ratings per IEC 60038 up to 1…

1.1 This Standard defines requirements for the periodic inspection of balance of plant pressure retaining systems, components, and supports that form part of a CANDU nuclear power plant using a risk informed in-service inspection (RI-ISI) methodology. Periodic inspection (see Annex A for additional guidance) is considered to include the fluid boundary portions of balance of plant systems,…

1.1 This Standard applies to single- or multiple-conductor, round, flat, or coiled appliance wiring material products classified as follows: a) Class I — internal wiring of equipment (single- or multiple-conductor constructions with or without an insulating covering, covering or jacket): i) Group A — not subject to mechanical abuse; and ii) Group B — potentially subject to mechanical abuse…

201.1.1 Scope Replacement: This International Standard applies to the BASIC SAFETY and ESSENTIAL PERFORMANCE of automatically-controlled BRACHYTHERAPY AFTERLOADING ME EQUIPMENT, hereafter referred to as ME EQUIPMENT. If a clause or subclause is specifically intended to be applicable to ME EQUIPMENT only, or to ME SYSTEMS only, the title and content of that clause or subclause will say so. If that…

1.1 This Standard applies to appliance plugs used as components of heater cord sets for use on cord- connected heating appliances rated for use on nominal single-phase system voltages of 240 V and less, designed to be used in dry nonhazardous locations in household and similar applications in accordance with the Canadian Electrical Code, Part I. 1.2 In this Standard, “shall” is used to express…

This Code covers all electrical work and electrical equipment operating or intended to operate at all voltages in electrical installations for buildings, structures, and premises, including factory-built relocatable and non-relocatable structures, and self-propelled marine vessels stationary for periods exceeding five months and connected to a shore supply of electricity continuously or from time…

This Recommendation | International Standard specifies the coded representation of picture information for digital storage media and digital video communication and specifies the decoding process. The representation supports constant bit rate transmission, variable bit rate transmission, random access, channel hopping, scalable decoding, bitstream editing, as well as special functions such as…

IEC 61557-8:2014 specifies the requirements for insulation monitoring devices (IMD) which permanently monitor the insulation resistance RF to earth of unearthed a.c. IT systems, of a.c. IT systems with galvanically connected d.c. circuits having nominal voltages up to 1 000 V a.c., as well as of unearthed d.c. IT systems with voltages up to 1 500 V d.c. independent from the method of measuring.…
