1 Scope Replacement This part of IEC 61558 deals with the safety of isolating transformers for general applications and power supply units incorporating isolating transformers for general applications. Transformers incorporating electronic circuits are also covered by this document. NOTE 1 Safety includes electrical, thermal and mechanical aspects. Unless otherwise specified, from here…

ISO/IEC TR 11801-9906:2025 covers cabling channel specifications, for cabling channels constructed from balanced single-pair cabling components, primarily intended for use in industrial automation and process control applications. The cabling channel specifications are intended to support ISO/IEC/IEEE 8802-3 single-pair Ethernet (SPE) link segment specifications in the following SPE physical…

This document provides detailed and rigorous procedures for the independent performance testing of all forms of ship in-water cleaning (IWC), including on all types of biofouling (i.e. biofilms/microfouling and macrofouling), all external submerged surfaces (i.e. hull and niche areas), and both proactive and reactive IWC systems with or without the capture, processing, and disposal of debris.…

This document specifies: —     the physical and chemical tests on raw rubbers; —     the standard materials, the standard test formulations, the equipment and the processing methods to evaluate the vulcanization characteristics for general-purpose chloroprene rubbers (CRs).

Contains more than 220 standard sheets covering device outline drawings and the types of semiconductor devices generally mounted in the packages. Published in the IEC since 1966, the drawings given in this publication represent the unification of national standards. The database version of this publication avails the standard sheets in PDF format and it also provides search facilities for easy…

1 Scope Replacement This part of IEC 61558 deals with the safety of separating transformers for general applications and power supply units incorporating separating transformers for general applications. Transformers incorporating electronic circuits are also covered by this document. NOTE 1 Safety includes electrical, thermal and mechanical aspects. Unless otherwise specified, from here…
