1 Scope

This standard specifies nitrate fertilizers capable of self-sustaining decomposition of the classification procedures, test methods and acceptance basis. This standard applies to ammonium nitrate fertilizer can continue to self-decomposition of the classification test.

2 Normative references

Terms of the following documents become provisions of this standard by reference in this standard. For dated reference documents, all later Amendments (not including errata content) or revisions do not apply to this standard, however, encourage the parties to agreements based on this standard Whether the latest versions of these documents. For undated references, the latest version applies to this standard. GB 6944 Classification and code of dangerous goods UN "Recommendations on the Transport of Dangerous Goods. Model Regulations" (Fifteenth revised edition)

3 Terms and Definitions

GB 6944 and the United Nations "on the Recommendations on the Transport of Dangerous Goods. Model Regulations" (Fifteenth revised edition) established the following terms and And definitions apply to this standard. 3.1 9 substances and articles (miscellaneous dangerous substances and articles) substancesandarticlesofClass9 (miscelaneousdan- geroussubstancesandarticles) Dangerous substances and articles not included in other classes during transport. 3.2 Fertilizer can be self-sustaining decomposition fertilizerscapableofself-sustainingdecomposition In partial-induced decomposition can be extended to the whole of the fertilizer.

4 classification program

If you submit a new product transportation component in line with its UN number UN2071 definition, classification should be implemented before the program paid transportation. 4.1 Sorted Test to determine the new products in the local decomposition caused by whether it will be extended to all the material. Recommended test methods, see section 5 of this standard Zhang, whether a product is ammonium nitrate fertilizer Class 9 substances and articles depends on the test results. 4.2 Packaging division All articles and 9 species of nitrate fertilizers are classified Ⅲ packing. 4.3 Exceptions Ammonium nitrate fertilizer having the composition UN2071 if self-sustaining experiments show that they are not easily decomposed and contained excess nitrate The mass fraction of less than 10%, can be considered from the UN "Recommendations on the Transport of Dangerous Goods. Model Regulations" constraints.

5 Test methods

5.1 Principle The transportation to be submitted in the form of nitrate fertilizers charged level Mounting wire mesh tank by heating the underlying fertilizer portion initiator Board solution. After removal of the initiating heat source, measuring the decomposition of fertilizer spread to the whole slot to determine whether a product is capable of self-sustaining decomposition of fertilizers. 5.2 Equipment and Materials 5.2.1 groove wire mesh 1.5mm, wire diameter 1mm square hole wire mesh (recommended stainless steel) mesh made with about an upper opening, the internal dimension 150mm × 150mm × 500mm groove, as shown in FIG. 1, the width of the groove placed 15mm, having a thickness of 2mm steel strip holder , The ends of the slots are available wire mesh 1.5mm thick stainless steel plate instead of 150mm × 150mm square. If the particle size of the fertilizer composition of the fertilizer to make the most of the screen pass undetected grooves, holes, slots smaller mesh lined with the application or use of a smaller mesh Screen test slot. During initiation, and should provide sufficient heat to maintain adequate to produce a uniform decomposition front. A --- steel sheet (150mm × 150mm, thickness 1mm ~ 3mm); B --- gas burner; C --- heat shield plate (thickness 2mm); D --- bracket (width of 15mm, a thickness of 2mm steel strip made); E --- Network (150mm × 150mm × 500mm) slot. FIG wire mesh tank 1 with gas burners And heating means mounted 5.2.2 Selection of one of the following two heating means for heating. 5.2.2.1 electric heating means A power means in a stainless steel box for the electric heater is 250W, which is placed at one end of the slot, as shown in FIG. stainless Steel cassette size is 145mm × 145mm × 10mm, steel wall thickness of about 3mm. While the box is not in contact with the fertilizer available 5mm Thick protective insulation board, while heating the protective foil or stainless steel plate. In millimeters A --- aluminum or stainless steel sheet (thickness 3mm); B --- insulation panel (5mm thick); C --- aluminum or stainless steel sheet (thickness 3mm); D --- the position of the heating means in the groove. Electrical heating means in FIG. 2 (power 250W) Gas heating means 5.2.2.2 A groove disposed in an end of 1mm thick steel sheets ~ 3mm and contact with the screen, as shown in FIG. The two gas burners solid Held on the holder groove. Sheet to the steel sheet is heated and maintained at a temperature of 400 ℃ ~ 600 ℃, i.e., dark red hot. 5.2.3 Thermal shield device In order to prevent the thermal spread along the outside of the groove, the groove away from the end of the heating installation at about 5cm 2mm thick steel plate as a heat shield. 5.2.4 Thermocouple Use the appropriate thermocouple. 5.3 Test procedure 5.3.1 placement test cell The test cell holder and placed under a fume hood to eliminate the decomposition gas, or placed in the open field in the flue gas can be easily dispersed. although This test is not risk of explosion, but it is recommended that a transparent plastic plate or the like between the protective shield and the observer test tank. 5.3.2 Fill release fertilizer In the transport vessel is loaded to be delivered in the form of fertilizers and fertilizer thermocouple placed in different positions. 5.3.3 heating caused by decomposition Heating or gas heating in the form of decomposition of the initiator used in the electrical end of the slot. Heating was continued until a sufficiently decomposed to produce the fertilizer, and observed Until propagation fronts (3cm ~ 5cm). In the case of products having high thermal stability, may be necessary to continue heating 2H; if fertilizer Show a tendency to melt, it should be carefully heated, such as using a small flame. 5.3.4 Record After the heating is stopped for about 20min, the recording position of the reaction front of the decomposition. The reaction front may be determined by differences in color, such as brown (not Decomposition fertilizer) to white (decomposed fertilizer), or by determining interposed therebetween adjacent two pairs of thermocouple display fronts from the reaction temperature. Propagation speed Level may be determined or recorded by thermocouples be determined by observing and timing. Whether or not a note should be decomposed after the heating is stopped or spread points Whether the solution spread to all the material. 5.4 results found 5.4.1 If the decomposition after heating is stopped continues to spread to all the material, the result referred to as "", which can be self-sustaining decomposition of ammonium nitrate fertilizer. 5.4.2 If the decomposition did not continue to propagate all the material after heating is stopped, the result as "-." 5.4.3 Sample test results are shown in Table 1. Note. ratio of NPK fertilizer as if it will not self-sustaining decomposition of standard, because depending on whether self-sustaining decomposition of chemical classes. Part of the sample test results in Table 1 Test substance propagation distance/cm Results Compound fertilizer NPK ratio of 50 17-11-22a Compound fertilizer NPK ratio of 15-11-8b 10 - Compound fertilizer NPK ratio of 14-14-14a 10 - Compound fertilizer NPK ratio of 21-14-14a 10 - Compound fertilizer NPK ratio of 50 12-12-18b a chloride-containing. b containing traces of cobalt and copper, but the chloride content is less than 1%. 0102-
