This document defines the detailed interface services and protocols used in a matching method based on multiple capability class structures. This document also defines a CPTI (Capability Profile Template Interface) Service Group, an Extended CPI (Capability Profile Interface) Service Group and an Extended Matcher Interface Service Group, which is extensions of the Type 1, Type 2 and Type 3…

IEC 60156:2018 RLV contains both the official IEC International Standard and its Redline version. The Redline version is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its previous edition. IEC 60156:2018 specifies the method for determining the dielectric breakdown voltage of insulating liquids at power…

IEC 60156:2018 specifies the method for determining the dielectric breakdown voltage of insulating liquids at power frequency. The test procedure is performed in a specified apparatus, where the oil sample is subjected to an increasing AC electrical field until breakdown occurs. The method applies to all types of insulating liquids of nominal viscosity up to 350 mm2/s at 40 °C. It is appropriate…

IEC 60335-2-31:2012+A1:2016+A2:2018 deals with the safety of electric range hoods and other cooking fume extractors intended for installing above, beside, behind or under household cooking ranges, hobs and similar cooking appliances, their rated voltage being not more than 250 V. The cooking appliance can be supplied by electricity or other fuels, such as gas. Appliances not intended for normal…

IEC 60335-2-21:2012+A1:2018 deals with the safety of electric storage water heaters for household and similar purposes and intended for heating water below boiling temperature, their rated voltage being not more than 250 V for single-phase appliances and 480 V for other appliances. Appliances not intended for normal household use but which nevertheless may be a source of danger to the public,…
