Preface
Article 8.1 in Chapter 4, Chapter 7 and Chapter 8 of this standard are mandatory provisions, and the rest are recommended provisions. This standard is for (GI310205-1988 "Ammonium phosphate, diammonium phosphate (granular)", GB10206-1988 "Ammonium phosphate by slurry method", HG/T32821990 "Powdered monoammonium phosphate" HG25581994 "Slurry" The revision of "Method of Diammonium Phosphate" merges the four standards mentioned in 1: into one item.
The main differences between this edition and the previous edition are:
1 The scope of application of the standard has been changed to "solid monoammonium phosphate and diammonium phosphate fertilizers suitable for production by various processes". 2 Product classification has been added .
3 Based on the actual situation of my country's phosphate rock resources, the existing production conditions of ammonium phosphate and diammonium phosphate, and the physical quality of water, the requirements for ammonium phosphate and ammonium phosphate... were adjusted, and the matching formula was added. As an indicator, the water-soluble phosphorus indicator is changed to the water-soluble phosphorus percentage of available phosphorus indicator.
This standard will replace GB10205-1988, GB10206--1988, HG/T3282-1990 and HG2558---1994
This standard is proposed by the State Administration of Petroleum and Chemical Industry. This standard is under the jurisdiction and interpretation of the National Fertilizer and Soil Conditioner Standardization Technical Committee. The drafting unit of this standard is: National Fertilizer Quality Supervision and Inspection Center ( Shanghai), Sichuan Shihua Co., Ltd. The main drafters of this standard: Yang - Yi, Huang Daxiong, Yang Xiaoxia, Jing Wenzhong, Shang Zhaocong. This standard was first published in 1988

This standard specifies the product classification, requirements, test methods, and inspection of solid monoammonium phosphate (MAP) and diammonium phosphate (DAP) fertilizers Rules, labeling, packaging, transportation and storage. This standard applies to solid monoammonium phosphate and diammonium phosphate fertilizers produced by various processes. 2 Reference standards
The provisions contained in the following standards are adopted in this standard. The references constitute the provisions of this standard. When this standard is published, the versions shown are valid. All standards will be revised, and parties using this standard should explore the possibility of using the following new versions of the standard GB/T1250-1989. Numerical expression and judgment methods GB/T6679-1986 General principles for sampling of solid chemical products GB8569--1997 Solid chemical fertilizer packaging GB/T10209.1-2001 Determination of total nitrogen content in ammonium phosphate and diammonium phosphate (post-distillation titration method) GB/T10209.2-2001 Determination of available phosphorus content in ammonium phosphate and diammonium phosphate GB/T10209.3--2001 Determination of moisture content in ammonium phosphate and diammonium phosphate GB/T10209.4--2001 Ammonium phosphate, Determination of diammonium phosphate particle size GB18382-2001 Fertilizer labeling content and requirements (neqISO7409:1984) 3 product classification | Ammonium and diammonium phosphate: granular ammonium phosphate and diammonium phosphate obtained by using phosphoric acid concentration method, neutralizing phosphoric acid with ammonia or using other methods other than slurry concentration method. 3.2 Granular monoammonium phosphate and diammonium phosphate by slurry method: granular monoammonium phosphate and diammonium phosphate obtained by neutralizing phosphoric acid with ammonia using the slurry concentration method
3.3 Powdered monoammonium phosphate: without Granulated monoammonium phosphate is divided into two categories: those made from high-quality phosphate rock as raw materials and made by phosphoric acid concentration method are Category 1 products, and those made from medium and low-grade phosphate rocks with high magnesium, iron and aluminum content are used as raw materials. The product obtained by slurry concentration method is a genuine product. 4 Requirements
