IEC 61439-2:2020(E) defines the specific requirements for the power switchgear and controlgear assembly (abbreviated ‘PSC-assembly’ throughout this document see 3.1.101) as follows: <ul> <li>assemblies for which the rated voltage does not exceed 1 000 V AC or 1 500 V DC;</li> <li>assemblies designed for a nominal frequency of the incoming supply or supplies not exceeding…

IEC 60120:2020 define the dimensions of a series of standard ball and socket couplings using the standard locking devices (see IEC 60372) in order to permit the assembly of insulators or metal fittings supplied by different manufacturers. This document applies to string insulator units of the cap and pin and long rod types and their associated metal fittings. For the pin ball and the socket,…

The ISO/IEC 10373 series defines test methods for characteristics of identification cards according to the definition given in ISO/IEC 7810. Each test method is cross‑referenced to one or more base standards, which can be ISO/IEC 7810 or one or more of the supplementary standards that define the information storage technologies employed in identification card applications. NOTE 1 Criteria for…

This document describes the characteristics of a Common Transport Service Account System (CTSA). It presents the common transport service account framework and associated use cases. The objective of the CTSA role model is to cover relevant transport services, the payment methods, the account types where the user of the service is charged for the service and that requires a more overall role and…

This document specifies requirements for Coriolis mass flow meter (MFM) systems installed on and used by vessels for the accurate measurement of bunker fuels received. It defines metrology and security requirements as well as testing requirements of the MFM system for the receiving vessel. This document complements ISO 8217, ISO 22192 and OIML R117. This document does not cover mass flow meters…

IEC 62373-1:2020 provides the measurement procedure for a fast BTI (bias temperature instability) test of silicon based metal-oxide semiconductor field-effect transistors (MOSFETs). This document also defines the terms pertaining to the conventional BTI test method.

IEC 62966-2:2020 is dedicated to aisle containment techniques for information technology (IT) equipment typically used in data centres, describes the quantification of its air tightness, in particular the air loss ratio that describes the content of the volumetric flow not used for cooling the IT equipment. This ratio provides an index of efficiency, being inversely proportional to efficiency (…

IEC 61760-1:2020 defines requirements for component specifications of electronic components that are intended for usage in surface mounting technology. To this end, it specifies a reference set of process conditions and related test conditions to be considered when compiling component specifications. The objective of this document is to ensure that a wide variety of SMDs can be subjected to the…

This document specifies requirements for three types of textile-reinforced thermoplastics hoses and hose assemblies of nominal size from 3,2 to 25. Each type is divided into two classes dependent on electrical conductivity requirements. They are suitable for use with: — oil-based hydraulic fluids HH, HL, HM, HR and HV as defined in ISO 6743‑4 at temperatures ranging from −40 °C to +93 °C…
