This International Standard describes a method for calculating the minimum approach distances for live working, at maximum voltages between 72,5 kV and 800 kV. This standard addresses system overvoltages and the working air distances or tool insulation between parts and/or workers at different electric potentials. The required withstand voltage and minimum approach distances calculated by the…

IEC 62701:2014 specifies requirements for recycled mineral insulating oils intended for use in transformers, switchgear, and similar electrical equipment in which oil is required for insulation and heat transfer. These oils are produced by processes employed offsite. Oils treated and reconditioned on-site are not within the scope of this standard. Oils with and without additives are within the…

Scope 1.1 This Standard describes the requirements, including quality system requirements, for the O&M of an HCF. It sets out specific requirements for a) buildings and architectural systems; b) site elements related to the building and its functions, including on-site access routes; c) on-site utilities; d) the building's mechanical, electrical, and information…

IEC 61936-1:2010+A1:2014 provides common rules for the design and the erection of electrical power installations in systems with nominal voltages above 1 kV a.c. and nominal frequency up to and including 60 Hz, so as to provide safety and proper functioning for the use intended. For the purpose of interpreting this standard, an electrical power installation is considered to be one of the…

ISO 14554-1:2013 specifies requirements for the demonstration of the capability of a manufacturer or a sub-contractor to produce welded constructions, fulfilling specified quality requirements, in one or more of the following: a) a contract between involved parties; b) an application standard; c) a regulatory requirement. The requirements contained within ISO 14554-1:2013 can be adopted in full…

ISO 14554-2:2013 specifies requirements for the demonstration of the capability of a manufacturer or a sub-contractor to produce welded constructions, fulfilling specified quality requirements, in one or more of the following: a) a contract between involved parties; b) an application standard; c) a regulatory requirement. The requirements contained within ISO 14554-2:2013 can be adopted in full…

IEC 61918:2013 specifies basic requirements for the installation of media for communication networks in industrial premises and within and between the automation islands, of industrial sites. This standard covers balanced and optical fibre cabling. It also covers the cabling infrastructure for wireless media, but not the wireless media itself. Additional media are covered in the IEC 61784-5…
