Foreword

GB/T 8570 "Determination of liquid anhydrous ammonia method" is divided into seven parts. - Part 1. Adoption of laboratory samples; - Part 2. Ammonia content; - Part 3. Residue content weight method; - Part 4. Residual content volumetric method; - Part 5. Moisture Fisher Fischer; - Part 6. Oil content gravimetric and infrared absorption spectroscopy; - Part 7. Iron content - phenanthroline spectrophotometric method. This part is part 4 of the GB/T 8570. This part of the replacement of GB/T 8570.4-1988 "liquid anhydrous ammonia residue content determination capacity method." The main differences between this edition and the previous edition are. Preparation and calibration of reagent solutions, standard titration solutions, etc. Execution of HG/T 2843 standards; --- increase the contents of the security warning; - standardize the standard format according to the new requirements. This section is proposed by the China Petroleum and Chemical Industry Association. This section is under the jurisdiction of the National Technical Committee on Standardization of Fertilizers and Soil Conditioners (SAC/TC105). This part of the drafting unit. the National Fertilizer Quality Supervision and Inspection Center (Shanghai), the Eastern Airlines Co., Ltd. Security Department. The main drafters of this section. Wu Juan, Feng Zhuo, Ji Min, Chen Jie. This part was first published in 1988. Determination of liquid anhydrous ammonia Part 4. Residue content volumetric method WARNING - Personnel using this standard should have practical experience in formal laboratory work. This standard does not indicate all possible security questions question. It is the responsibility of the user to take appropriate safety and health measures and to ensure compliance with the conditions of the relevant national laws. Liquid anhydrous ammonia high Toxic to the skin, mucous membranes and eyes are corrosive, contact can cause severe burns. Operation should be properly protected.
