Fruits, vegetables and derived products — Determination of mercury content — Flameless atomic absorp...
The method consists in decomposing of organic matter in a sulfuric-nitric acid medium, reducing of mercury(II) to metallic mercury by the action of tin(II)chloride, entraining of the mercury vapour by a current of air and determing in an enclosed apparatus.
Manganese ores and concentrates — Determination of nickel content — Dimethylglyoxime spectrometric m...
Two methods are specified. Method A is applicable to products having a nickel content of 0.01 to 1.0 % (m/m), method B is applicable to products having a nickel content of 0.005 to 1.0 % (m/m). Both methods specify principle, reactions (method A only), reagents, apparatus, sample, procedure and expression of results.
Fertilizers — Determination of total nitrogen content — Titrimetric method after distillation
The method consists in reducing of nitrate to ammonia by chromium powder in acid medium, converting of organic and urea nitrogen into ammonium sulfate by digestion with concentrated sulfuric acid in the presence of a catalyst, distilling of the ammonia from an alkaline solution and absorbing in an excess of standard volumetric sodium hydroxide solution. The method is not recommended for materials…
Copper and copper alloys — Determination of phosphorus content — Molybdovanadate spectrometric metho...
The method is applicable to the determination of phosphorus contents between 0.000 5 and 0.5 % (m/m). ISO 4741 specifies principle, reagents, apparatus, procedure, expression of results and test report.
Copper and copper alloys — Determination of chromium content — Flame atomic absorption spectrometric...
The method is applicable to the determination of chromium contents between 0.003 and 2.0 % (m/m). ISO 4744 specifies principle, reagents, apparatus, sampling, procedure, expression of results and test report. An International Standard dealing with the sampling of copper and copper alloys is in preparation.
Manganese ores — Sampling — Part 1: Increment sampling
Specifies methods for taking samples of manganese ores to be used at the places of dispatch and acceptance of ores for determining the chemical composition and moisture content of a consignment.The methods are applicable to both the manual and mechanical sampling of natural or processed ores. Details of the hammer and shovel method are given in the annex.
