What are the standards for air tightness detection leakage?It is determined by the upper and lower intake limits and the upper and lower leakage limits artificially set in the program.

So how do manufacturers set the values ​​of "upper and lower air intake limits" and "upper and lower leakage limits"?

The upper and lower air intake limits are generally set based on the test pressure of the product.The lower limit of air intake is generally greater than or equal to the product test pressure; the upper limit of air intake is generally 5-50kpa higher than the test pressure; there are three methods for setting the upper and lower limits of leakage:

1. Experience method,Air tightness detector manufacturer/产品生产厂家根据过往的检测经验进行设置；

2. Experimental method: Use the manufacturer to conduct small batch testing based on the samples, and analyze and obtain relevant values ​​​​according to the method of "first gas inspection, then soak in water";

3. Customer-given standards: Customers have their own standard values.For example, within 50pa, within 100pa, within 3ml/min, etc.

But the most common one is the second method - experimental method. I have shared relevant knowledge in the following article.Click the link below to get there.

It talks about one-to-one correspondence between the air inspection and traditional water inspection results through experiments to obtain the judgment standards for air tightness testing.If you are interested, you can click to read it to understand the operation and principles.

After introducing how the judgment criteria for air tightness testing are obtained, let’s share which air tightness testing equipment is better to use.

Air tightness detectorRoughly divided into two types:

1. Direct pressure

2. Differential pressure

When we are choosing instruments, there are many instruments from various brands and manufacturers on the market, and the styles are also confusing.

Therefore, when selecting instruments, we generally consider the following factors:

1. Whether you can understand the text;

2. Is screen interaction button-based or touch-based?

3. Whether the program is simple and easy to use;

4. Whether the instrument complies with human body mechanics;

5. Whether the fault can be quickly found;

6. Is the after-sales service convenient and fast?
