The document provides a general methodology for improving the accuracy and completeness of circular economy related information based on the usage of a Product Circularity Data Sheet when acquiring or supplying products. This general methodology contains then a set of requirements that need to be established by an organization aiming to use the concerned data sheet when acquiring or supplying…
Ferrotitanium — Determination of titanium content — Titrimetric method
The method is applicable to ferrotitanium having titanium contents between 20 and 80 % (m/m). Specifies principle, reagents, apparatus, sample, procedure, expression of results and test report. Figures show the Bunsen valve and the apparatus for titration.
Chromium ores and concentrates — Determination of chromium content — Titrimetric method
The method is applicable to products having a chromium content greater than 7 % (m/m). Should be read in conjunction with ISO 6629. Specifies principle, reagents, apparatus, procedure and expression of results.
Plastics — Polymer dispersions — Determination of free formaldehyde
This International Standard describes two methods for the determination of free formaldehyde (HCHO) in polymer
dispersions. The procedure has been evaluated using acrylic, acrylonitrile butadiene, carboxylated styrenebutadiene
and vinyl acetate polymer dispersions. Both test methods may also be applicable to polymer dispersions
of other compositions.
Method A is the preferred method for polymer…
