Classification and performance test of chemical packaging

according to the structural strength and protective performance of the packaging and the degree of danger of the contents, the packaging of dangerous goods is divided into three categories:

class I packaging: the goods are relatively dangerous, and the packaging strength requirements are high

class II packaging: the goods are of medium risk and the requirements for packaging strength are high

class III packaging: the goods have little danger and the requirements for packaging strength are general

the general technical conditions for transport packaging of dangerous goods (GB) stipulates four test methods for dangerous goods packaging, namely stacking test, drop test, air tightness test and hydraulic test

stacking test: place the hard load plate on the top surface of the test package, place heavy objects on the plate, and observe whether the stacking is stable under a certain stacking height (3 meters by land and 8 meters by sea) and a certain time (generally 24 hours), and whether the packaging of gbt17104 (1) 997 metal tube ring tensile test method is deformed and damaged

drop test: according to the drop packaging of different drop directions and heights, the fixed assets of the paper industry increased by 5.1% year-on-year in 2018. Observe whether the packaging is damaged and leaked. For example, the falling direction of the steel barrel is: for the first time, the convex edge of the barrel is impacted on the ground in an oblique line; if there is no convex edge, it is impacted at the joint between the barrel body and the barrel bottom. The second time, the weakest place that was not tested for the first time, will be found after thinking, such as longitudinal welds, closures, etc

air tightness test: immerse the package into the water, inflate and pressurize the package, and observe whether there are bubbles, or apply soap or other suitable liquids on the bucket joints or other places prone to leakage, and then inflate and pressurize the package to observe whether there are bubbles

hydraulic test: according to different packaging types, select different pressures to pressurize for 5min, and observe whether the packaging is damaged. For example, acid resistant jars and ceramic jars are used in different fields according to the needs of different users. The selection pressure of class I packaging is 250kPa, the pressure of class II packaging is 200KPa, and the pressure of class III packaging is 200KPa

the package containing chemicals must be inspected by the designated department and can be used only after meeting the relevant test standards
