Leather — Chemical tests — Determination of matter soluble in dichloromethane and free fatty acid co...
This document specifies a method for the determination of the substances in leather which are soluble in dichloromethane. This method is applicable to all types of leather.
Not all fatty and similar substances can be extracted from leather with organic solvents; they may be in part soluble and partly bound to the leather. On the other hand, the solvent can dissolve non-fatty substances, for…
Leather — Chemical determination of chromic oxide content — Part 3: Quantification by atomic absorpt...
This document describes a method for the determination of chromium in aqueous solution obtained from leather. This is an analysis for total chromium in leather; it is not compound specific or specific to its oxidation state.
This method describes the determination of chromium by atomic absorption spectrometry and is applicable to leathers which are expected to have chromic oxide contents in…
Leather — Chemical determination of chromic oxide content — Part 1: Quantification by titration
This document describes a method for the determination of chromium in aqueous solution obtained from leather. This is an analysis for total chromium in leather; it is not compound specific or specific to its oxidation state.
This method describes the determination of chrome by iodometric titration and is to be applicable to chromium-tanned leathers which are expected to have chromic oxide…
Wind turbines - Part 11: Acoustic noise measurement techniques
IEC 61400-11:2012+A1:2018 presents measurement procedures that enable noise emissions of a wind turbine to be characterised. This involves using measurement methods appropriate to noise emission assessment at locations close to the machine, in order to avoid errors due to sound propagation, but far away enough to allow for the finite source size. The procedures described are different in some…
Copper, lead, zinc and nickel concentrates — Sampling procedures for determination of metal and mois...
This document sets out the basic methods for sampling copper, lead, zinc and nickel concentrates from moving streams and stationary lots, including stopped-belt sampling, to provide samples for chemical analysis, physical testing and determination of moisture content, in accordance with the relevant International Standards. Where the concentrates are susceptible to significant oxidation or…
Industrial automation systems and integration — Standardized procedures for production systems engin...
ISO 18828-4:2018 specifies a set of key performance indicators in production planning, which allow comparison and monitoring of the production planning process in a standardized framework.
As a first step, the utilization of the KPIs is elaborated in order to organize the indicators in a multi-level system taking different ranges of the planning process into account. This development of a multi-…
