For solid packaging, other items with similar physical properties (such as mass, particle size, etc.) to the intended goods can be used instead; for liquid packaging, other items with similar physical properties (such as density, viscosity) to the intended goods can be used instead. Generally, water can be used instead. 8.1.2 The packaging containing solids should be filled to 95% of its volume, and the packaging containing liquids should be filled to 98% of its volume. 8.1.3 Paper and hard fiberboard packaging should be pre-treated with temperature and humidity according to the requirements of GB/T4857.2 according to the circulation environment conditions.
8.1.4 Before the drop test of plastic packaging, the temperature of the sample and the contents should be reduced to -18°C or below. When the contents are liquids: they should still be liquid after the temperature is reduced, and antifreeze can be added if necessary. 8.1.5 The venting device on the package should be replaced by a closure device similar to ventilation or the vent hole should be closed. 8.1.6 Before the performance test, the containers and protective materials such as seals, adsorbents, and pads that directly contain dangerous goods should also be tested for compatibility with the intended contents for a certain period of time (e.g., 6 months). 8.2 Main test items and qualified standards

Class I packaging: 250kPa; Class II packaging: 200kPa. Class III packaging: 200kPa. 8.2.1.2 The stacking test and qualification standards for various types of transport packaging are shown in Table 1. 8.2.2 Drop test 8.2.2.1 The test method should comply with the requirements of GB/T4857.5. Qualification standards The container is considered qualified if it does not leak. The jar or bottle is considered qualified if it does not break. |tt||8.2.2.2 If water is used instead for the test, the density of the liquid inside should be calculated according to the following formula: Group I packaging:
Density ≤1.2, then the drop height = 1.2×1.5 = 1.8 (m) Density p>1.2, then the drop height = p×1.5 (m) Group II packaging:
Density p≤1.2, then the drop height is 1.2 (m) Density p>1.2, then the drop height = p×1.0 (m) Group III packaging:
Density ≤1.2, then the drop height = 1.2-1.5 = 0.8 (m) Density p>1.2, then the drop height = p1.5 (m) Where:
p—liquid density, in grams per cubic centimeter (g/cm*); 1.0, 1.5—coefficients.

The airtightness test and qualification standards for various types of packaging containers are shown in Table 3. 10
All containers intended to contain
liquids shall be subjected to hydraulic pressure test.1 Stacking test
Test method
Install the test container with the indicator
Hydraulic test
Test pressure
Packaging: 250kPa;
pressure gauge, tighten the barrel cover, connect the hydraulic pump, and inject water into the container to pressurize it.
When the pressure gauge pointer reaches the required pressure
, plastic containers and composite packaging with plastic inner containers should be subjected to a 30-minute pressure test. Containers and composite packaging of other materials should be subjected to a 5-minute pressure test. The test pressure should be applied evenly and continuously, and kept stable. If the sample is supported, it shall not affect the test effect. Install an indicator pressure gauge on the test container, tighten the barrel cover, connect the hydraulic pump, and fill water into the container to pressurize it. When the pressure gauge pointer reaches the required pressure, change the constant pressure for 5 minutes. 8.2.1.1 The test method shall comply with the provisions of GB/T4857.3.
