IEC TR 60601-4-3:2018 contains a series of recommendations developed by an expert working group of IEC subcommittee 62A in response to questions of interpretation of IEC 60601-1:2005 and related collateral standards in the IEC 60601 series. IEC TR 60601-4-3:2018 is primarily intended to be used by: – manufacturers of medical electrical equipment; – test laboratories and others responsible for…

IEC 62056-8-4:2018 specifies DLMS/COSEM communication profiles for narrow-band OFDM power line carrier PRIME neighbourhood networks using the modulation as specified in Recommendation ITU-T G.9904:2012. Three communication profiles are specified: • a profile using the IEC 61334-4-32 LLC layer; • a profile using TCP-UDP/IPv4; • a profile using TCP-UDP/IPv6.

IEC 62056-8-4:2018 spécifie les profils de communication DLMS/COSEM pour les réseaux de voisinage OFDM utilisant les courants porteurs en ligne PRIME utilisant la modulation conformément à la Recommandation UIT-T G.9904:2012. Trois profils de communication sont spécifiés: • un profil utilisant la couche LLC IEC 61334-4-32; • un profil utilisant TCP-UDP/IPv4; • un profil utilisant TCP-UDP/IPv6.

IEC 62464-1:2018 specifies measurement procedures for the determination of many essential image quality parameters for MR EQUIPMENT. Measurement procedures as addressed in this document are suitable for – quality assessment in the ACCEPTANCE TEST, and – quality assurance in the CONSTANCY TEST. Required levels of performance for ACCEPTANCE TESTS are not provided for all tests. This document…

Les procédures de mesure développées dans le présent document conviennent pour – l'évaluation de la qualité dans le cadre de L'ESSAI D'ACCEPTATION, et – l'assurance qualité dans le cadre de L'ESSAI…

This specification describes the form and establishes the interpretation of programs written in the C# programming language. It describes: — The representation of C# programs; — The syntax and constraints of the C# language; — The semantic rules for interpreting C# programs; — The restrictions and limits imposed by a conforming implementation of C#. This…

IEC 60479-1:2018(E) provides basic guidance on the effects of shock current on human beings and livestock. This basic safety publication is primarily intended for use by technical committees in the preparation of standards in accordance with the principles laid down in IEC Guide 104 and lSO/lEC Guide 51. It is not intended for use by manufacturers or certification bodies.

This document provides an overview of approaches of sample preparation (i.e. pre-treatment and size-fractionation) for analytical measurements applied to surface and drinking water, potentially containing relevant amounts and types of metal and metal oxide nano-objects, including collection from source and storage of samples, pre-concentration of analytes, and their fractionation.

This document establishes a procedure to calibrate IR-TRACC displacement transducers. Like all other sensors used on dummies, calibration is required. The calibration is carried out with the sensor disassembled from the dummy. The procedure is valid for sensors with analogue as well as digital output.
