GB 10205-2009Monoammonium phosphate and diammonium phosphate (English PDF)

Foreword

The standard Chapter 4, Section 6, Chapter 7 and Chapter 8 in 8.1 are mandatory, others are recommended.

This standard replaces GB 10205-2001 "monoammonium phosphate and diammonium phosphate." the main difference between this version and GB 10205-2001 are.

--- According to the status and monoammonium phosphate production process conditions and the level of physical quality of DAP phosphate resources of MAP, DAP-soluble phosphorus and water accounted for the percentage of phosphorus and other indicators have been adjusted.

Since the implementation of standards from products manufactured should implement the new standards; six months after the date of implementation of the standard, the market monoammonium phosphate, diammonium phosphate production Product packaging prohibit labeling GB 10205-2001.

The standard proposed by China Petroleum and Chemical Industry Association.

This standard by the National Standardization Technical Committee and soil conditioners Fertilizers (SAC/TC105) centralized.

1 Scope

This standard specifies the solid monoammonium phosphate (MAP) and diammonium phosphate (DAP) fertilizer product classifications, requirements, test methods, inspection regulations Then, labeling, packaging, transportation and storage.

This standard applies to all kinds of technology, the use of solid MAP and DAP fertilizer.

3 Product Categories

MAP and DAP product by the appearance of granular and powdered into two categories, according to the production process is divided into two categories.

3.1 by slurry MAP and DAP. magnesium, iron, high aluminum content of low grade phosphate rock as raw material, the slurry was concentrated legal system Monoammonium phosphate, diammonium phosphate.

3.2 MAP and DAP traditional method. the use of other methods than the slurry concentration was monoammonium phosphate, diammonium phosphate.

4 Requirements

4.1 Traditional method of granular MAP and DAP should meet the requirements of Table 1, and shall comply with the indicated values.
