Live working - Minimum approach distances for a.c. systems in the voltage range 72,5 kV to 800 kV - ...
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 between parts and/or workers at different potentials.
The required withstand voltage and minimum approach distances calculated by the method described in this standard are evaluated taking…
Plastics — Aromatic isocyanates for use in the production of polyurethanes — Determination of hydrol...
ISO 15028:2004 specifies a method for the determination of the hydrolysable-chlorine content of toluene-2,4-diisocyanate, toluene-2,6-diisocyanate or mixtures of the two. This test method may also be applied to other isocyanates of suitable solubility, such as crude or refined polymeric isocyanates.
Household and similar electrical appliances - Safety - Part 2-13: Particular requirements for deep f...
Deals with the safety of electric deep fat fryers, frying pans and other appliances in which oil is used for cooking, and intended for household use only, their rated voltage being not more than 250 V.This standard does not apply to deep fat fryers having a recommended maximum quantity of oil exceeding 4 l (refer to IEC 60335-2-37) or commercial multi-purpose cooking pans (refer to IEC 60335-2-39…
Electromagnetic compatibility (EMC) - Part 4-4: Testing and measurement techniques - Electrical fast...
Establishes a common and reproducible reference for evaluating the immunity of electrical and electronic equipment when subjected to electrical fast transient/bursts on supply, signal, control and earth ports. The test method documented in this part of IEC 61000-4 describes a consistent method to assess the immunity of an equipment or system against a defined phenomenon.
The standard defines…
Information technology — Metadata registries (MDR) — Part 4: Formulation of data definitions
ISO/IEC 11179-4:2004 specifies requirements and recommendations for constructing definitions for data and metadata. Only semantic aspects of definitions are addressed; specifications for formatting the definitions are deemed unnecessary for the purposes of this standard. While especially applicable to the content of metadata registries as specified in ISO/IEC 11179-3, ISO/IEC 11179-4:2004 is…
