Soil quality — Screening method for water content — Determination by refractometry
This document specifies a method for rapid determination of water content in soils. The method is based on refractive index measurement of a sucrose solution after it is mixed with a soil sample.
It is applicable to the determination of water content in geological or geotechnical research as well as geotechnical engineering. In addition, it can be used for commercial work in a variety of fields,…
Cards and security devices for personal identification — Contactless proximity objects — Part 3: Ini...
This document describes the following:
- polling for proximity cards or objects (PICCs) entering the field of a proximity coupling device (PCD);
- the byte format, the frames and timing used during the initial phase of communication between PCDs and PICCs;
- the initial Request and Answer to Request command content;
- methods to detect and communicate with one PICC among…

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…
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…
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…
