Iron ores — Determination of manganese content — Periodate spectrophotometric method
This second edition cancels and replaces the first edition (ISO 3886:1977), some clauses and annex A of which have been technically revised. The method is applicable to a concentration range of 0,02 to 8 % (m/m) of manganese in natural iron ores, and iron ore concentrates and agglomerates including sinter products.
Cold-reduced carbon steel strip with a maximum carbon content of 0,25 %
Applies to strip furnished to two levels of closer tolerances than cold-reduced carbon steel sheet, with specific quality, specific hardness requirements or mechanical properties, specific edge and specific finish. This product is commonly produced in thicknesses of 6 mm and under, and in widths up to 600 mm exclusive, in coils and cut lengths. Temper requirements or mechanical properties may be…

This third edition cancels and replaces the second edition (ISO 312-1980), of which it constitutes a minor revision. Specifies principle, reagents, apparatus, sample, procedure and expression of results. A figure gives an example of apparatus.
Commercially dry virgin cork, ramassage, gleanings, corkwood refuse and corkwaste — Definitions and ...
Applies to material defined in ISO 633 the moisture content of which is not higher than 14 % as determined in accordance with ISO 2386. Gross mass of bales is the size of commercially dry cork including packaging. The type of cork and the name of the exporting country shall be indicated on the bales.
High nitrogen content, straight ammonium nitrate fertilizers — Determination or oil retention
The result of the method is a measure for the porosity of the material. The method is applicable to substances which do not contain materials soluble in gas oil and which are prilled or granular. It consists in total immersing of a test portion in gas oil for a specified period, followed by the draining away and the removal of surplus gas oil under specified conditions, and measuring of the…
