This paper presents some concrete practice of the technical tests performed by the authors during these years, which include almost all the safety performance tests of the imported CO, cylinders. Some differences between the national standard GBl1640- 89 and the external standards in these technical tests are also pointed out. It provides reference to the further perfection of the safety performance test standard of aluminum gas cylinders.
