IEC/IEEE 80005-1:2019+AMD1:2022+AMD2:2023 describes high-voltage shore connection (HVSC) systems, onboard the ship and on shore, to supply the ship with electrical power from shore. This document is applicable to the design, installation and testing of HVSC systems and addresses: - HV shore distribution systems, - shore-to-ship connection and interface equipment, - transformers/reactors, -…

This document specifies a titration method for the determination of rare earth content in 15 kinds of individual rare earth metals (lanthanum, cerium, praseodymium, neodymium, samarium, europium, gadolinium, terbium, dysprosium, holmium, erbium, thulium, ytterbium, lutetium and yttrium) and their oxides. The determination ranges for the rare earth content in mass fraction are as follows: —    …

IEC TR 63222-100:2023, which is a Technical Report, collects relevant information on power quality impacts from, e.g., CIGRE reports, case studies, research findings, etc., in order to uncover the mechanisms of how electrical equipment/installations/system are impacted by power quality disturbances, as well as to fully understand the guidelines for power quality management. The contents of this…

This document specifies a reference method for the determination of the nitrogen content of meat and meat products by the Kjeldahl principle.

This document specifies two reference methods for the determination of the moisture content of meat and meat products: a direct drying method and a distillation method. The direct drying method is applicable to meat and meat products with low volatile substances in addition to moisture. The distillation method is applicable to meat and meat products with high volatile substances in addition to…

IEC TS 61496-5:2023 provides particular requirements for the design, construction and testing of non-contact electro-sensitive protective equipment (ESPE) designed specifically to provide whole-body detection of a person or persons as part of a safety-related system, employing radar protective devices (RPDs) responsive to diffuse reflection of radar signals for the sensing function using…

IEC 62271-202:2022 specifies the service conditions, rated characteristics, general structural requirements and test methods of enclosed high-voltage prefabricated substations. These prefabricated substations are cable-connected to AC high-voltage networks with an operating voltage up to and including 52 kV and power frequencies up to and including 60 Hz. They can be manually operated from inside…

2 SCOPE This standard applies to any products containing a claimed recycled plastic content of at least 5%, which is either credited according to the Chain of Custody (CoC) mass balance model or actual physical recycled content. This standard is not intended to determine the mechanical, physical and chemical qualities and properties of a product, nor the adequacy of the product’s constraint…

This document specifies an analytical procedure for the determination of very high purity gold with a nominal content of and above 999,99 ‰ (parts per thousand, by mass), using an inductively coupled plasma mass spectrometer (ICP-MS).

This document specifies four methods for the determination of the content of the following groups of organic peroxides used as rubber vulcanizing agents. There are three titration methods and one gas-chromatography method. a)       titration method A for group a: Peroxyketals: 1,1-Di(tert-butylperoxy)cyclohexane (DTBPC; CAS Registry Number®:3006-86-8) 1,1-Di(tert-butylperoxy)-2-methylcyclohexane…
