What is a leak?

Gas leakage is the amount of gas flowing through a section in a unit time. Gas volume is pressure and volume or mass. The basic formula of volume leakage is as follows:

Why talk about air tightness?

1. Service life

2. Safety considerations

3. Quality of experiment

4. Environmental regulations

5. Universal quality standards

6. End users trust product quality

7. Reproduce the experimental conditions

How is air tightness defined?

1. Actual leak detection of samples

Step 2: Experience

3. Calculate the allowable leakage rate according to the experimental requirements

4. Developer observations (should be very good and hard to implement)

Typical leakage protection standards (as shown below)
