This International Standard provides general principles and detailed requirements for the design and formulation of all types of instructions that will be necessary or helpful for products of all kinds ranging from small, simple ones, such as a tin of paint, to large or highly complex ones, such as a large industrial installation. It is

This document specifies general and safety requirements for light-emitting diode (LED) modules: • non-integrated LED modules (LEDni modules) and semi-integrated LED modules (LEDsi modules) for operation under constant voltage, constant current or constant power; • Integrated LED modules (LEDi modules) for use on DC supplies up to 250 V or AC supplies up to 1

This International Standard applies to auxiliary electromechanical contact units associated (or intended to be associated) with circuit-breakers for overcurrent protection, and with residual current operated circuit-breakers with or without integral overcurrent protection for household and similar installations, having a rated voltage not exceeding 440 V a.c. and 250 V d.c., and a rated current not

This document defines requirements applied in the design and manufacture of electrical installations and equipment to be used on rolling stock to protect persons from electric shocks. This document is applicable to rolling stock of rail transport systems, road transport systems if they are powered by an external supply (e.g. trolley buses), magnetically levitated transport

This document gives guidance on current practice for the characteristics of multimedia analogue interfaces to achieve interoperability between equipment from different manufacturers. It is not a performance standard. Recommendations for interfaces for equipment used in vehicles, and for analogue video interfaces for broadcast and similar equipment, are not given. Refer to IEC 60958 for the
