All packages should be leak-free. For packages with inner coating (plating), the inner coating (plating) layer should also be intact. b) For packages containing solids, after the drop test, even if the closure device no longer has the ability to prevent leakage, the inner packaging or contents should still remain intact and leak-free.
c) The outer packaging of composite packaging or combination packaging shall not have any damage that may affect transportation safety, and the contents shall not leak from the inner packaging or inner container, and the inner container or inner packaging shall not leak. If there is an inner coating (plating) layer, it should be intact. d) The outermost layer of the bag or the outer packaging shall not have any damage that may affect transportation safety. e) A small amount of the contents may leak from the closure when it falls, but it shall not continue to leak after falling. ") The packaging of Class 1 substances is not allowed to leak during the drop process. No leakage
No leakage
The test sample has no leakage. The inner container of the composite packaging and the inner packaging of the close-fitting packaging are also leak-free. The test sample does not have damage that may have an adverse effect on transportation safety, or deformation that may reduce its strength or cause unstable stacking of the package. Before evaluation, the plastic container should be cooled to ambient temperature. 7.2.1.1 The performance test items of various common air transport dangerous goods packaging containers are shown in Appendix A. 7.2.1.2 Each packaging container used to hold liquids should be subjected to an airtightness test. If the outer packaging of the combination packaging can meet the airtightness requirements or its cushioning and adsorbent material can completely absorb the retained contents and prevent it from leaking from the outer packaging, then its Inner packaging may be exempted from this test. 7.2.1.3 If the outer packaging of a combination package and different types of inner packaging have passed the test, the outer packaging may also be equipped with multiple inner packagings similar to these different types. In addition, the following types of inner packaging are allowed to be used without further testing when they have the same effectiveness in performance.

7.2.6.2.1 The total gauge pressure inside the package measured at 55°C (i.e. the pressure of the substance contained plus the pressure of air or inert gas minus 100kPa) multiplied by a safety factor of 1.5. pr=(pMsX1.5)kPa, not less than 95kPa. 7.2.6.2.2 1.75 times the vapor pressure of the cargo to be transported at 50°C, minus 100kPa. Pr=(Vp5×1.75)-100kPa, not less than 100kPa.
7.2.6.2.3 1.5 times the vapor pressure of the cargo to be transported at 55°C, minus 100kPa. pr=(Vp55×1.5)100kPa, not less than 100kPa.
Where:
test pressure, in kPa;
total gauge pressure measured in the container at 55°C; PMss
Vsa——vapor pressure of goods at 50°C;
Vps5——vapor pressure of goods at 55°C. 7.2.6.2.4 The test pressure of packaging containers intended to contain Class I liquid dangerous goods is 250kPa. 7.2.6.3 Test method
Start the hydraulic dangerous packaging tester, apply hydraulic pressure continuously and evenly to the inner packaging, open the exhaust valve at the same time, exhaust the residual gas in the test container, and then close the exhaust valve. Plastic and plastic composite packaging, including their closures, should withstand the specified constant hydraulic pressure (gauge pressure) for 30 minutes, and other containers, including their closures, should withstand the specified constant hydraulic pressure (gauge pressure) for 5 minutes. 7.2.7 Stacking test
7.2.7.1 Test equipment
According to the requirements of GB/T4857.3.
7.2.7.2 Test method
Plastic barrels, plastic cans and composite packaging 6HH1 and 6HH2 intended to contain liquids shall be subjected to a stacking test at a temperature of 40°C for 28 days. The stacking time for other packaging containers is 24 hours. Other test methods shall be in accordance with the requirements of GB/T4857.3. 7.2.7.3 Stacking load
Where:
P——Load applied, in kilograms (kg); K——Deterioration coefficient, K value is 1;
H—Stacking height (not less than 3m), in meters (m); h—Height of a single package, in meters (m); m-
Hh,
—Gross mass (gross weight) of a single package, in kilograms (kg). 7.3 Performance inspection rules
7.3.1 The manufacturer shall ensure that the packaging of dangerous goods for air transport produced by it complies with the provisions of this standard and shall be inspected by the relevant inspection departments in accordance with this standard. The user has the right to request acceptance inspection of the received products in accordance with the provisions of this standard. 7.3.2 Inspection items: Inspect each item according to the requirements of 7.2. 7.3.3 Performance test conditions
Performance test should be carried out when any of the following conditions occur in the packaging of dangerous goods for air transport: when a new product is put into production or an old product is switched to another product;
After formal production, if there are major changes in structure, materials, or processes that may affect product performance;
During normal production, once every six months; When resuming production after a long-term suspension of production: 10
