3. Testing methods
• Appearance: visual • Total Nitrogen: according to SR EN 15478:2009. The Nitrogen from the urea is mineralised in
the presence of concentrated sulphuric acid; ammonia is distilled in an alkaline environment, and it is absorbed in an excess solution of sulphuric acid; the excess of sulphuric acid is titrated.
• Biuret: according to STAS 8495-89 and SR EN 15479:2009. A red-purple complex is formed between biuret and the divalent copper ion, in an alkaline environment, in the presence of a potassium sodium tartrate solution; the coloured complex is photometrically measured at a wavelength of 546 nm.
• Water content determination: according to SR EN 13466-1:2002, Karl–Fischer method. It is a testing method for specific determination of the water contained in fertilizers, through titration with Karl–Fischer reagent, using methanol as a medium for water extraction.
• Granulometry (determination of particle size): according to STAS 8495-89, section 4.6, mechanical sieving on sieves with mesh size of 1 and 3.15 mm and to SR ISO 2591-1:1998.
• Alkalinity: is determined according to SR ISO 1593:1999 (standard cancelled) and STAS 5698-87 section 4.8., by dissolving 50 g of urea in 200 cm3 of water and 0.01N HCl titration in the presence of a mixed indicator solution (Methyl Red–Methylene Blue). • Formaldehyde: the determination is based on compounding the formaldehyde in a strong acid
environment with chromotropic acid and measuring the absorbency of the pink-purple compound at a wavelength of 570 nm.
