After the vacuum test program is started, when the pressure in the chamber reaches the standard required
relative vacuum value, the vacuum system stops, and the equilibration time of 5 minutes is turned on. After the
balancing time elapses, the vacuum test is started for 10 minutes. After the test is completed, the system returns
to normal pressure.
After the vacuum test is finished, the system will prompt the result on the program end interface and save the
record in the memory. If the automatic printing function is set and the printer is connected, the test result will be
printed at the same time.
When the vacuum test is passed, the message is “vacuum test success”. Indicates that the system's leak rate
meets the design requirements. Print the information as follows:

B&D Test
B&D test is used to check the steam penetration of this sterilizer to porous permeable loads, such as cotton
fabrics. Select the B&D test in the test program interface (Figure 5.1).
Test methods and test results are judged in accordance with the
information and requirements provided by the test package
manufacturer.
