explosive substances as a whole tatalcnntents All substances or articles may not have a compatihility group gmnp in the class of explosives. If two or more substances or articles can be safely stowed or transported together without significantly increasing the risk of accidents or increasing the degree of hazard in quantitative conditions, they can be regarded as a compatibity group. 4 Classification 4.1 Classification of civil explosives According to the model of the transport protocol for dangerous goods (13th revised edition), civil explosives belong to Class 1. Class 1 is specifically divided into S, see Table 1. Table 1 Classification of civil explosives. : Item 1 includes materials and items that are both explosive and non-explosive. Item 2 includes materials and items that are both explosive and non-explosive. Item 3 includes materials and items that are both explosive and non-explosive. Item 4 includes materials and items that are both explosive and non-explosive. Item 5 includes materials and items that are both explosive and non-explosive. Item 6 includes materials and items that are both explosive and non-explosive. Item 7 includes materials and items that are both explosive and non-explosive. Item 8 includes materials and items that are both explosive and non-explosive. Item 9 includes materials and items that are both explosive and non-explosive. Articles, the impact of which is limited to the twisted parts, it is estimated that there will be a large error in the film, and it is not far from the view. The external fire is almost the same as the explosion of the gold packaging contents. There is a risk of explosion, but it is not sensitive. This refers to the overall external risk, but it can be converted into a small explosion or burn under normal transportation. The weight of the material is very small. You do not know that there is an overall explosion. This item includes only a few explosive materials that have been exposed to pressure and have a small possibility of causing accidents. Note that 1. The risk of explosion of the most important article is the explosion of the most important article. 4.2 Classification of groups The physical and chemical properties, frying properties, inner and outer packaging styles, special hazards and other different characteristics of explosives are divided into A, C, DFF, G, IIJ, K, L, N and S, a total of 13 groups, see Table 2. Table? The description of the article is that the article contains explosive substances and does not contain two or more effective fuses. If the article itself does not have a first-class fuse, it has explosive properties and needs a first-class detonator and a special fire effect. The price of the fire group will be included in the output. Products with explosive qualifications or their enhancing properties as propellants, or with slow-acting explosive substances: for example, products with two types of explosives or heat-propellant, or products containing "special products lacking selected explosive materials and/or containing more than one effective protective device, products with two types of explosive materials, without initiating devices, with safety propellants (combined with filter bodies, rubber or naturally occurring substances outside the limit). Products containing secondary ignition charges, low initiating devices, with triggering charges (containing dangerous substances or self-contained substances outside the limit) or with small propelling charges.
Pyrotechnics Products with pyrotechnic properties or containing three types of explosives, more sensitive substances (water-sensitive substances, more sensitive substances, more sensitive substances) or more sensitive substances. , self-degrading products, products that change into colloids, cold products, etc. (except those that contain explosive substances and degradable substances).

Type (a) — Random test. Type (b)
Kennan test, Type () — Time/stress test. For the test method, see the Test and Standard Specification for Dangerous Goods (4th edition). 6.2.2 The purpose of the test is to answer the question in bottle 4 in the picture of the identification process for dangerous goods <Figure A1>: "Is it an explosive substance?" In the test, as long as one of the test results is "10", the test group is considered to be explosive. 6. 3 Test series 2
6.3.1 Test items:
Type of test (a) — gram test, type 1) — electric test, (c) — time/film force test, see the "Manual of Test Standards and Methods for the Diagnosis of Materials" (1st revised edition) 6.3.2 The purpose of the test is to answer the question in Figure 5 (A) whether the material is strong enough to be recognized as an explosive. In the test, as long as one of the test items is correct, the answer to the question is "+" or "-". 6.4 Test series 3
6.4.1 Type of test - sensitivity test
6.4.1.1 Test apparatus
The Federal Material Inspection Bureau HAM instrument or other equivalent apparatus shall be used. 6.4.1.2 Test products
For solid materials other than in the form of grit or strands, the following points shall be observed:-- Powdered materials shall be sieved (with a sieve opening of 0.1 mm). For materials with more than one component, the residue used for testing shall be representative of the original material. - Materials compressed, injected or otherwise grown shall be sieved in small pieces. The residue passing through a 1.5 mm sieve but not exceeding 0.5 mm shall be used for testing. For materials containing more than one component, the residue used for testing shall be representative of the original material.
- Materials obtained in commercial form shall be tested in the form of tablets (small pieces) with a diameter of 4 mm (largest diameter, m, thickness 3 mm).
For powdered materials, the sample shall be measured using a measuring device with a capacity of 40 mm (diameter 3.7 mm, height 3.7 mm). For liquid materials, use a pipette with a diameter of 1 m. For powder, paste or glue, light material, the upper part of the test rail is in contact with the test rail, but not flattened. The liquid is filled in the test sample and the pressure between the control surface and the guide ring is applied. The impact on the depth gauge is determined by the impact on the column.
6.4.1.3 Test procedure
According to the formula = (J)m#ax (kp)g (take 10N/kg) × (m). The test is carried out once every 13 minutes. If during this test "explosion, spark or flame" is detected, the test is then gradually reduced until "decomposition" or "large reaction" is observed. Repeat the test for half an hour and if no explosion occurs, repeat five times: if not, then gradually reduce the energy again until the limit test is completed. If within 10 and a half hours the energy level is lowered and "decomposition" (change in energy or large reaction) or "large reaction" (no explosion) is observed, then the test is then gradually increased until "explosion" is observed for the first time: then reduce the energy again until the limit test is completed. The energy is increased until the low-pass impact energy is determined. 6.4.1.4 Test decision
If the minimum exchange impact energy of a "detonation" is 2 in the 6-pass test, the test conclusion is "one", which means that the material has not been transported in the form of a test. Otherwise, the result is "one". Note that other methods that are equivalent to this method may be used. 6.4.2 Type (h) - Friction test E.4.2.1 Test receiver
National Bureau of Material Inspection BAM friction tester or other equivalent instrument, 5
GI 19455—2004
6.4.2.2 Test samples
Usually, the test is carried out in the form of the material or the size when it is received. The material with the smallest amount of moisture is tested. In addition, for solid materials other than cooked or colloid, the following points should be observed: 1. The light powder is collected through a sieve (full hole 1.5m) and the material that has been sieved is used for sugar test! For materials containing more than one ingredient, the original quality can be changed before the test. The material with more than one ingredient should be sieved through a sensitive block. The material can be separated by a 0.5m dynamic force. For materials with more than one ingredient, the sieved material can be used for the test. The quality is tested in the form of a small round piece with a volume of 1mm (the center of the test is about 1mm). The source of the test is about 2.3m (2.3m in diameter and 2.4m in depth). The plate or colloidal material is measured with a 2mm.5mr belt. 6.4.2.3 Test process
Each porcelain table can only be used for 1 minute. The two ends of the sample can be tested twice, and the two surfaces of the dense plate can be tested once. Fix the porcelain plate on the frame so that the sea pattern can be cut in the direction of movement. Put the rod on the sample, add the required appropriate pressure on the drop, and start the test switch. Pay attention to ensure that you are sticking to the sample F..When the porcelain plate is really covered with a 3-load test, start the test with 3 loads. If any explosion, spark or fire is detected in the second test, then reduce the load step by step and continue the test until there is "decomposition" (color change or taste) or "no reaction" (that is, "explosion" is detected in the third test, then reduce the load step by step until there is no "explosion" (color change or taste) or "no reaction" (that is, "explosion" is detected in the fourth test, then reduce the load step by step until there is no "explosion" in the fifth test, and then reduce the load step by step until the lowest load is determined. If the result of the third test is "decomposition" or "no reaction", then remember to repeat the test. For example, in this test with the highest weight of 6 If the test results are "no reaction" or "no reaction" in all six tests, the substance is considered to be non-irritating to the friction. If the test results are "no reaction" in one of the six tests, the load is reduced as described above. 5.4.2.4 Test results If the minimum friction load is less than N in one of the tests, the test result is "no reaction", i.e. the substance is too dangerous to be returned in its test form. If the test result is "no reaction", the substance is considered to be non-irritating to the friction. 5.4.3 Type 6.4.3.1 Test only: The temperature is recorded at 75°C. The temperature of the electric box with a motor and ventilation device is 200 °C.
6.4.3.2 Test procedure for thermoelectricity:
Put a small amount of test sample in a hot water tank. If the sample does not have a drying reaction during the test, the following steps should be performed. If a drying reaction or pyrophoric material occurs, it is not heated enough for transportation. Put the 506 sample into a melting cup and put it into a drying oven after heating. Place the sample at 75℃ and keep the sample at 51℃ or until it explodes. The earlier one shall prevail. If no pyrophoric or pyrophoric reaction occurs but the sample is self-heated (or decomposed), the following test shall be performed: If the sample does not show any unstable phenomenon, it is not necessary to perform a separate test.
Put a 10g or 100m3 sample in a hot water tank. If the change is less than 1r/min, place the sample in a hot water tank. - Place the sample in the test tube and place the sample on a scale. Wait until the valves T1 and T2 are halfway up the tube. Heat the test and reference materials together and place the thermocouples. Place the thermocouples 1 and 2 in the test tube. When the sample reaches 48°C, measure the temperature difference between the sample and the reference and record the decomposition temperature.
6.4.3.3 Test judgment: If fire or explosion occurs in step 2 of the procedure, give the result. If no changes are observed, give the result: If fire or explosion occurs in step 3 of the procedure, give the result. If the temperature difference (heating temperature) is 3 or more, give the result. 19455—2C04
“，”. If the expected heat recorded is less than 3 degrees, but certain phenomena are observed, additional test sections shall be performed to evaluate the test results. If the test result is “10”, the material is too thermally unstable to be transported. G.4.4 Type (a) - Small-scale combustion test 6.4.4.1 Test material: unsaturated sawdust? 6.4.4.2 Test procedure: Change 10 mg of the test substance into the filter cup, insert the filter cup through the wooden base (30 cm long, 30 cm wide, 1.3 cm thick). For substances that are not easy to ignite, the floating height is increased to 2.5 cm>. Then ignite the wooden net with the igniter. The test is carried out twice with 000. The explosion risk is increased to 6.4.4.3 Test judgment: The test sample is empty and the "selective explosion" occurs. The test result is "+", the substance is too dangerous. Not transported in the form in which it was tested. If the sample is not ignited or is "ignited and then burned", the test result is "-" "E, 5 test series to 1
