Solid fertilizers-Reduction of samples

BS DD CEN/TS 15479:2006 肥料.光谱测定法测定尿中缩二脲

This Technical Specification specifies a method for the determination of biuret in urea. The method is applicable to urea and urea-based fertilizers.

Fertilizers - Spectrophotometric determination of biuret in urea

BS DD CEN/TS 15475:2006 肥料.测定氨态氮

This Technical Specification specifies a method for the determination of the ammoniacal nitrogen content in fertilizers. The method is applicable to all nitrogenous fertilizers including compound fertilizers, in which nitrogen is found exclusively either in the form of ammonium salts or ammonium salts together with nitrates. The document is not applicable to fertilizers containing urea, cyanamide or other organic nitrogenous compounds.

Fertilizers - Determination of ammoniacal nitrogen

BS DD CEN/TS 15477:2006 肥料.测定水溶液中尿中钾含量

This Technical Specification specifies a method for the determination of water-soluble potassium, which is applicable to all potassium fertilizers listed in Annex I of the Regulation (EC) No 2003/2003.

Fertilizers - Determination of the water-soluble potassium content

BS DD CEN/TS 15476:2006 肥料.用氏合金还原蒸馏法测定氮和氨态氮

This Technical Specification specifies a method for the determination of nitrate and ammoniacal nitrogen with reduction using Devarda alloy (modified for each of the variants a, b and c). The method is applicable to all nitrogenous fertilizers, including compound fertilizers, in which nitrogen is found exclusively in nitrate form or in ammoniacal and nitrate form.

Fertilizers - Determination of nitric and ammoniacal nitrogen according to Devarda

ISO 7742:1988 固体肥料 试样的缩分

The method consists in passaging of the material through a rotating sample divider and collecting of the fractions, followed by rejection or recombination of some of the fractions. By choosing suitable equipment it is applicable to any mass above a minimum defined by size and number of particles.
