This standard applies to geotechnical site investigations performed in permafrost zones to provide essential information for the design of: ? foundations for all types of buildings; ? rehabilitation plans for existing building foundations. It also applies to the measuring of site-specific conditions in the process of performing geotechnical site investigations. It does not apply to post-…

IEC 61709:2017 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 61709:2017 gives guidance on the use of failure rate data for reliability prediction of electric components used in…

IEC 61709:2017 gives guidance on the use of failure rate data for reliability prediction of electric components used in equipment. The method presented in this document uses the concept of reference conditions which are the typical values of stresses that are observed by components in the majority of applications. Reference conditions are useful since they provide a known standard basis from…

IEC 61851-1:2017 applies to EV supply equipment for charging electric road vehicles, with a rated supply voltage up to 1 000 V AC or up to 1 500 V DC and a rated output voltage up to 1 000 V AC or up to 1 500 V DC. Electric road vehicles (EV) cover all road vehicles, including plug-in hybrid road vehicles (PHEV), that derive all or part of their energy from on-board rechargeable energy storage…
