Short-circuit currents - Calculation of effects - Part 1: Definitions and calculation methods
IEC 60865-1:2011 is applicable to the mechanical and thermal effects of short-circuit currents. It contains procedures for the calculation of: the electromagnetic effect on rigid conductors and flexible conductors, the thermal effect on bare conductors. For cables and insulated conductors, reference is made, for example, to IEC 60949 and IEC 60986. For the electromagnetic and thermal effects in d…
Electromagnetic compatibility (EMC) - Part 3-14: Assessment of emission limits for harmonics, interh...
IEC/TR 61000-3-14:2011(E) is a Technical Report which provides guidance on principles that can be used as the basis for determining the requirements for the connection of disturbing installations to low voltage (LV) public power systems. For the purposes of this part of IEC 61000, a disturbing installation means an installation (which may be a load or a generator) that produces disturbances:…
Terminal markings for valve device stacks and assemblies and for power conversion equipment
IEC 61148:2011 is applicable to the terminal markings for the main circuits of valve device stacks and assemblies, and of integrated conversion equipment. The terminal markings refer to stacks, assemblies and equipment comprising semiconductor valve devices. The object of this standard is to specify a logical alphanumeric marking system for the identification of the external main terminals of the…

Performance standards in building — Definition and calculation of area and space indicators
ISO 9836:2011 deals with the definition and calculation of surface area and volume indicators.
In defining area measurement, ISO 9836:2011 uses three measurement concepts:
the intra-muros and extra-muros concept used in many parts of the world;
the wall centre method of measurement used in many parts of the world;
variations on these methods to comply with certain…
