Gas analysis — Analytical methods for hydrogen fuel — Proton exchange membrane (PEM) fuel cell appli...
This document specifies the validation protocol of analytical methods used for ensuring the quality of the gaseous hydrogen (H2) at hydrogen distribution bases and hydrogen fuelling stations for road vehicles using proton exchange membrane (PEM) fuel cells. It also gives recommendations on the calculation of an uncertainty budget for the amount fraction.
This document is established mainly for…
Specification for radio disturbance and immunity measuring apparatus and methods - Part 2-3: Methods...
CISPR 16-2-3:2016+A1:2019 specifies the methods of measurement of radiated disturbance phenomena in the frequency range of 9 kHz to 18 GHz. The aspects of measurement uncertainty are specified in CISPR 16-4-1 and CISPR 16-4-2. It has the status of a basic EMC publication in accordance with IEC Guide 107, "Electromagnetic compatibility - Guide to the drafting of electromagnetic compatibility…
Rotating electrical machines - Part 18-41: Partial discharge free electrical insulation systems (Typ...
IEC 60034-18-41:2014+A1:2019 defines criteria for assessing the insulation system of stator/rotor windings which are subjected to voltage-source pulse-width-modulation drives. It applies to stator/rotor windings of single or polyphase AC machines with insulation systems for converter operation. It describes qualification tests and quality control (type and routine) tests on representative samples…
Industrial systems, installations and equipment and industrial products — Structuring principles and...
IEC 81346-2:2019 establishes classification schemes with defined object classes and their associated letter codes, and is primarily intended for use in reference designations and for designation of generic types.
The classification schemes are applicable for objects in all technical disciplines and all branches of industry.
IEC 81346-2:2019 is a horizontal publication also intended for for use by…
Environmental testing - Part 2-69: Tests - Test Te/Tc: Solderability testing of electronic component...
IEC 60068-2-69:2017+A1.2019 outlines test Te/Tc, the solder bath wetting balance method and the solder globule wetting balance method to determine, quantitatively, the solderability of the terminations. Data obtained by these methods are not intended to be used as absolute quantitative data for pass–fail purposes. The procedures describe the solder bath wetting balance method and the solder…
