This document describes a method for testing the susceptibility to antifungal agents of yeasts, including Candida spp. and Cryptococcus neoformans, that cause infections. The reference method described here has not been used in studies of the yeast forms of dimorphic fungi, such as Blastomyces dermatitidis and/or Histoplasma capsulatum variety capsulatum. Moreover, testing filamentous fungi (…

IEC 60034-9:2021 specifies test methods for the determination of sound power level of rotating electrical machines and specifies maximum A-weighted sound power levels for factory acceptance testing of network-supplied, rotating electrical machines in accordance with lEC 60034-1, having methods of cooling according to lEC 60034-6 and degrees of protection according to lEC 60034-5, and having the…

IEC 60034-9:2021 CMV contains both the official standard and its commented version. The commented version provides you with a quick and easy way to compare all the changes between IEC 60034-9:2021 edition 5.0 and the previous IEC 60034-9:2003+AMD1:2007 CSV edition 4.1. Futhermore, comments from IEC TC 2 experts are provided to explain the reasons of the most relevant changes. IEC 60034-9:2021…

IEC TS 62607-9-1:2021(E) establishes a standardized method to characterize spatially varying magnetic fields with a spatial resolution down to 10 nm for flat magnetic specimens by magnetic force microscopy (MFM). MFM primarily detects the stray field component perpendicular to the sample surface. The resolution is achieved by the calibration of the MFM tip using magnetically nanostructured…

IEC TS 62607-6-19:2021(E) establishes a standardized method to determine the chemical key control characteristic • elemental composition for powder consisting of graphene-based material by • CS analyser and ONH analyser. The method as described in this document determines the content of carbon (C), sulfur (S), oxygen (O), nitrogen (N) and hydrogen (H). The carbon (C) and sulfur (S) content…

IEC TS 62607-6-6:2021(E) establishes a standardized method to determine the structural key control characteristic • strain uniformity for single-layer graphene by • Raman spectroscopy. The width of the 2D-peak in the Raman spectrum is analysed to calculate the strain uniformity parameter which is a figure of merit to quantify the influence of nano-scale strain variations on the electronic…

IEC TS 62607-6-10:2021(E) establishes a standardized method to determine the electrical key control characteristic – sheet resistance (Rs) for films of graphene-based materials by – terahertz time domain spectroscopy (THz-TDS). In this technique, a THz pulse is sent to the graphene-based material. The transmitted or reflected THz waveform is measured in the time domain and transformed to the…

This document specifies the International Standards, including clauses and subclauses, with which conformity to the quality requirements of ISO 3834-2, ISO 3834-3 or ISO 3834-4 can be claimed. NOTE      For brazing, see ISO 22688.

IEC 61850-7-420:2021 defines the IEC 61850 information models to be used in the exchange of information with distributed energy resources (DER) and Distribution Automation (DA) systems. DERs include distribution-connected generation systems, energy storage systems, and controllable loads, as well as facility DER management systems, including aggregated DER, such as plant control systems, facility…

This document defines a method for the sizing of non-functional software requirements. It complements ISO/ IEC 20926:2009, which defines a method for the sizing of functional user requirements (FUR).1 This document also describes the complementarity of functional and non-functional sizes, so that sizing both functional and non-functional requirements (NFR) do not overlap. It also describes how…
