This standard is one nitrate fertilizer, P and K series of standard test methods for nitrate, which are listed below national standards. --- GB/T 10511-2008 "After distillation of total nitrogen content for nitrophosphate titration method"; --- GB/T 10512-2008 "nitrate fertilizer phosphorus content - Quinoline phosphomolybdate gravimetric method"; --- GB/T 10514-2012 "nitrophosphate determination of water content - Oven method"; --- GB/T 10515-2012 "Determination of particle size Nitrophosphates"; --- GB/T 10516-2012 "nitrate fertilizer particles have an average crush strength of determination." This standard replaces GB/T 10513-1989 "nitrophosphate determination of water content Karl Fischer method." The main difference between this version and the previous version are. --- Reagent solution, such as a standard titration solution preparation and calibration methods are the implementation of HG/T2843 standard; --- Volume to absorb the test solution by 10.0mL 5.0mL; --- Increased content security warning. The standard proposed by China Petroleum and Chemical Industry Association. This standard by the National Standardization Technical Committee fertilizer and soil conditioner. This standard was drafted. Tianji Coal Chemical Industry Group Co., Ltd., National Fertilizer Quality Supervision and Inspection Center (Shanghai). The main drafters. Zhang Jiahong, Wang Yin, Li Yongping, Guo Lian Hong, Yang. This standard was first published in 1989. Nitrophosphate determination of free water content Karl Fischer1 ScopeThis standard specifies the determination of P and K fertilizer nitrate, the free water content by the Karl Fischer method. This standard applies to all kinds of technology, the nitrate fertilizer, measuring water content of phosphorus and potassium nitrate free.2 Normative referencesThe following documents for the application of this document is essential.
