1 Scope This International Standard gives the minimum requirements relative to specification, manufacture, selection, application and maintenance of tools, devices and equipment for live working. It provides the type of information which is useful to skilled persons in order to make the use of tools, devices and equipment safer. This type of information includes: • the characteristics of tools,…

ISO/IEC 19794-1:2011 describes the general aspects and requirements for defining biometric data interchange formats. The notation and transfer formats provide platform independence and separation of transfer syntax from content definition. ISO/IEC 19794-1:2011 defines what is commonly applied for biometric data formats, i.e. the standardization of the common content, meaning, and representation…

IEC 61709:2011 gives guidance on how failure rate data can be employed for reliability prediction of electric components in equipment. Reference conditions are numerical values of stresses that are typically observed by components in the majority of applications. Reference conditions are useful since they are the basis of the calculation of failure rate under any conditions by the application of…
