IEC 60728-11:2023 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 60728-11:2023 deals with the safety requirements applicable to fixed sited systems and equipment. As far as applicable, it is also valid for mobile and temporarily installed systems, for example, caravans. Additional requirements may be applied, for example, referring to: - electrical installations of buildings and overhead lines, - other telecommunication services distribution systems, - water distribution systems, - gas distribution systems, - lightning systems. This document is intended to provide requirements specifically for the safety of the system, personnel working on it, subscribers and subscriber equipment. It deals only with safety aspects and is not intended to define a standard for the protection of the equipment used in the system. IEC 60728-11:2023 cancels and replaces the fourth edition published in 2016. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition. a) Replacement of references to IEC 60065 and IEC 60950-1 with references to IEC 62368-1. b) Addition of subclauses 4.4 to 4.6. c) Revised definition of class I equipment, class II equipment, main earthing terminal, see 3.1.6, 3.1.8 and 3.1.31. d) Addition of definitions for harm, hazard, ordinary person, instructed person, skilled person, see 3.1.22, 3.1.23, 3.1.39, 3.1.40 and 3.1.41. e) Additional requirement to provide details on the equipment installed, see 4.1. f) Additional mechanical, design and construction requirements, see 4.2.2. g) Changes to the accessible part requirements, see 4.2.3. h) The current carrying capacity and dielectric strength of components is now obligatory, see 8.1.3. i) The assessment of the risk of lightning strike is now obligatory, see Figure 10. j) Extension of remote feeding voltage on subscriber feeder, see Table 1.
