This document establishes the minimum characteristics required for the presentation and identification of periodicals including not only the obvious traditional elements that print periodicals typically display (e.g. title, ISSN, publisher, date), but also the "footprints" of periodicals published on digital dynamic media that enable them to be traced along the path of their history,…

This document explains fundamental concepts and describes the metamodel, data categories, and XML styles: DCA (Data Category as Attribute) and DCT (Data Category as Tag). It also specifies the methodology for defining TBX dialects. The audience for this document is anyone wishing to create a new dialect compliant with TBX. This document can also be used to analyze and to understand a…

IEC 60335-2-29:2016+A1:2019 deals with the safety of electric battery chargers for household and similar use having an output not exceeding 120 V ripple-free direct current, their rated voltage being not more than 250 V. Battery chargers intended for charging batteries in a household end use application outside the scope of the IEC 60335 series of standards are within the scope of this standard.…
