This part of IEC 60947 covers low-voltage arc quenching devices, hereinafter referred to as AQDs, which are intended to eliminate arc-faults in low-voltage assemblies (typically low-voltage switchgear and controlgear assemblies in accordance with the IEC 61 439 series), by creating a lower impedance current path, to cause the arcing current to transfer to the new […]

This part of IEC 60904 describes the procedure for correcting the spectral mismatch error introduced in the testing of a photovoltaic device, caused by the mismatch between the test spectrum and the reference spectrum (e.g. AM1 .5 spectrum) and by the mismatch between the spectral responsivities (SR) of the reference device and of the device

This part of IEC 60904 describes procedures for the measurement of current-voltage characteristics ( I-V curves) of photovoltaic (PV) devices in natural or simulated sunlight. These procedures are applicable to a single PV solar cell, a sub-assembly of PV solar cells, or a PV module. They are applicable to single-junction mono-facial PV devices. For other

This part of IEC 60869 applies to fibre optic passive power control devices. These have all of the following general features: – they are passive in that they contain no optoelectronic or other transducing elements; – they have two ports for the transmission of optical power and control of the transmitted power in a fixed

This part of IEC 60749 describes a test to determine the effect of variable frequency vibration,within the specified frequency range, on internal structural elements. This is a destructive test. It is normally applicable to cavity-type packages. NOTE This test method describes a swept sine test. A random vibration test is described in JEDEC document JESD

This part of IEC 60603-7 covers 8-way unshielded free and fixed connectors, it is intended to specify the common dimensions, mechanical, electrical and environmental characteristics and tests for the family of IEC 60603-7-x connectors. These connectors are intermateable (according to IEC 61076-1 level 2) and interoperable with other IEC 60603-7 series connectors.

This International Standard applies to the BASIC SAFETY and ESSENTIAL PERFORMANCE of MEDICAL ELECTRICAL EQUIPMENT and MEDICAL ELECTRICAL SYSTEMS,hereafter referred to as ME EQUIPMENT and ME SYSTEMS. 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
