This document specifies a method for the determination of the moisture and volatile matter content of oilseeds.

This document specifies the preparation methods of the test samples for the qualitative and quantitative analysis of specific chemical substances in fireworks. The document applies to the following substances to be tested using ISO 22863 (all parts): — hexachlorobenzene; — lead and lead compounds; — arsenic or arsenic compounds; — mercury compounds; — chlorates; — white…

This document specifies a method for the determination of the whey to casein protein ratio, ranging from 20:80 to 80:20 in cow milk-based infant formula powders. This method does not apply to the analysis of infant formulas containing hydrolysed protein or proteins from other sources (e.g. plants or milk from other mammals).

IEC TS 62749:2020 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 TS 62749:2020 specifies the expected characteristics of electricity at the SUPPLY TERMINALS of public low,…

This document describes simplified methods for taking samples of solid biofuels in small scale applications and storages including preparation of sampling plans and reports. The main focus is on storages with a size of ≤100 t. This document is applicable to the following solid biofuels: 1) fine (up to about 10 mm nominal top size) and regularly-shaped particulate materials that can be sampled…

IEC TS 62749:2020 specifies the expected characteristics of electricity at the SUPPLY TERMINALS of public low, medium and high voltage, 50 Hz or 60 Hz, networks. NOTE 1 The boundaries between the various voltage levels can be different for different countries/regions. In the context of this TS, the following terms for system voltage are used: - low voltage (LV) refers to less than or equal to 1…

This document specifies a flame atomic absorption spectrometric method (FAAS) for the determination of the vanadium content in steel. The method is applicable to vanadium contents between 0,01 % (mass fraction) and 0,80 % (mass fraction), provided that the tungsten content in a 1,0 g test portion is not higher than 1,0 % and/or the titanium content is not higher than 0,5 %.

IEC TS 62607-4-8:2020 specifies a test method for the determination of water content in electrode nanomaterials for nano-enabled electrical energy storage devices, using the Karl Fischer coulometric titration method. This document includes: - recommendations for sample preparation, - outlines of the experimental procedures used to measure electrode nanomaterial properties, and - methods of…

This document specifies a gravimetric method for the determination of the silicon content in steel and cast iron. The method is applicable to silicon contents between 0,10 % (mass fraction) and 5,0 % {mass fraction). NOTE For samples containing molybdenum, niobium, tantalum, titanium, tungsten, zirconium or high levels of chromium, the results are less accurate than for unalloyed matrixes.

This document specifies the CXPI data link layer and the CXPI physical layer. The DLL is based on: — priority-based CXPI network access; — non-destructive content-based arbitration; — broadcast frame transfer and acceptance filtering; and — node related error detection and error signalling. The CXPI physical layer (PHY) requirements comprise of: — physical signalling (PS) sub-…
