IEC 62271-200:2021 is applicable to prefabricated metal‑enclosed switchgear and controlgear assemblies designed for: – alternating current; – rated voltages above 1 kV and up to and including 52 kV; – service frequencies up to and including 60 Hz; – indoor and outdoor installation. The assembly can include air-insulated and/or fluid-filled compartments. This third edition cancels and…

IEC PAS 63267-3-30:2021 which is a publicly available specification, certain dimensional limits of an 16F MM angled PC rectangular polyphenylene sulphide (PPS) ferrule optical interface in order to meet specific longitudinal offset requirements for fibre-to-fibre interconnection. Ferrules made from the material specified in this document are suitable for use in categories C, OP, OP+, I and E as…

IEC 63002:2021 defines common charging interoperability guidelines for power sources (external power supplies (EPSs) and other Sources) used with computing and consumer electronics devices that implement IEC 62680-1-3 (USB Type-C Cable and Connector Specification). This document defines normative requirements for an EPS to ensure interoperability; in particular, it specifies the data…

This document specifies minimum requirements for personal vibration exposure meters (PVEM). This document is applicable to instruments designed for measurements of whole-body vibration in the context of industrial hygiene applications (according to ISO 2631-1, ISO 2631-2 and ISO 2631-4) and/or hand-arm vibration (according to ISO 5349-1) together with the associated exposure times. This document…

in 1.2. These devices are intended to be used indoors only or as outdoor use devices in a commercial or industrial environment. The device is battery powered using either lead acid batteries or lithium based batteries that, if rechargeable, are charged through a conductive system while either on board or off board the device. 1.2 Mobile platforms that are covered by this Standard are intended…

IEC 60335-2-68:2021 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 60335-2-68:2021 deals with the safety of electrical portable, non-self-propelled motor-operated spray…

IEC 60335-2-68:2021 deals with the safety of electrical portable, non-self-propelled motor-operated spray extraction machines with or without attachments and with or without electrical heating elements, intended for commercial indoor use. This standard applies to machines for commercial use. The following list, although not comprehensive, gives an indication of locations that are included in the…

This document specifies test methods and performance metrics to evaluate the behaviour of a vehicle equipped with lane keeping assistance system (LKAS, see 3.2). For this purpose, variables relevant to vehicle dynamics as well as controllability of a vehicle with LKAS and their measurement methods are defined. A system requiring a driver intervention is excluded from the scope. This document…

IEC 61557-12:2018+A1:2021 specifies requirements for power metering and monitoring devices (PMD) that measure and monitor the electrical quantities within electrical distribution systems, and optionally other external signals. These requirements also define the performance in single- and three-phase AC or DC systems having rated voltages up to 1 000 V AC or up to 1 500 V DC. These devices are…

This document describes and defines the five metrics of skills and capabilities. This document also provides the formula for each metric and describes the common metrics which employ the five metrics. This document also highlights issues that need to be considered when interpreting the skills and capabilities data, especially when deciding on the appropriate intervention internally and when…
