How to conduct air tightness testing in Shenzhen?Complete step-by-step guide

Shenzhen, as an important base for scientific and technological innovation in China, is not only a center for high-tech enterprises, but also a laboratory for cutting-edge fields such as materials science and construction technology.For high-standard companies that pay attention to product and construction quality, air tightness testing is an important link that cannot be avoided.The company passes air tightness testing to ensure the safety and durability of the product in actual usage scenarios.This not only improves the market competitiveness of the product, but also meets the growing high-performance needs of users.If you want to know how to conduct air tightness testing in Shenzhen, Hirays will provide you with comprehensive guidance to help you deal with this important step calmly.

1. Preparation

Before starting the air tightness test, adequate preparations need to be made.Including understanding specific test standards, determining test items and objects, preparing test instruments, etc.For enterprises in Shenzhen, air tightness testing is usually carried out in accordance with international standards such as ASTM E283, ISO 9972 or national standard GB/T 7106.It is important to emphasize that understanding these standards in advance can ensure the accuracy and validity of the test.It is also necessary to prepare relevant test equipment, such as air tightness tester, flow meter, pressure gauge, etc.The selection of these devices should be based on the test object and the test standard.It is also necessary to ensure that the test object is in a stable state and has no external interference factors.

2. Clean the test object

Before testing can begin, the test object must be thoroughly cleaned.Whether it is building doors and windows, electronic product casings, or other test objects, the surface must be completely clean and free of dust, oil, or other impurities, as these impurities may affect the air tightness test results.In an environment with high humidity and high dust content like Shenzhen, cleaning work is particularly important.Use professional cleaners and lint-free cloths to complete the cleaning work to ensure the accuracy and reliability of test results.

3. Install test equipment

Once the cleaning is complete, installation of the air tightness testing equipment can begin.Normally, the test equipment needs to be sealed and connected to the object being tested for subsequent air tightness testing.Taking building doors and windows as an example, ensure that all openings and gaps are sealed during installation.If it is an air tightness test of an electronic product shell, the air inlet and outlet of the air tightness tester need to be connected according to the standard interface.During the installation process, attention should be paid to the fact that the connections should be well sealed to prevent virtual connections or air leakage, which is directly related to the accuracy of the test.

4. Set test parameters

After the equipment is installed, the next step is to set the test parameters.This step mainly includes setting test pressure, test time, and other related parameters.For different test objects, the parameter settings will be different.Taking building doors and windows as an example, the test pressure is usually set between 50Pa and 100Pa, and the test time is usually between 15 minutes and 30 minutes.For air tightness testing of electronic products, the test pressure and time may be different and set according to the specific requirements of the product.Parameters must be set appropriately in accordance with relevant industry standards and specific product and test requirements.

5. Start testing

After all preparations are completed, the air tightness test can be officially started.The air tightness of the object being tested is tested through testing equipment.During this process, the equipment will test its sealing performance by inflating or pumping air into the object to be measured.Normally, the device will display real-time test data, including core indicators such as air pressure and flow rate.At this time, you need to pay close attention to the values ​​displayed by the device to ensure that the data during the test is accurate.If abnormal values ​​are found, it may be necessary to pause the test and check that the device connections are properly sealed.

6. Record and analyze data

After the test is completed, the test data needs to be fully recorded and analyzed.This step mainly includes organizing data, drawing data curves, and analyzing the air tightness of the tested object.The data obtained from the test equipment includes key indicators such as air pressure changes and flow changes.These data can not only be used to determine whether the measured object meets the air tightness requirements, but can also be used to find out the specific reasons for poor air tightness through further analysis.If it is found that the test object has air tightness problems, it can be improved and optimized accordingly.

7. Respond to emergencies

During the actual air tightness test, various emergencies may be encountered, such as equipment failure, data anomalies, etc.For these emergencies, contingency plans are needed.For example, if an equipment fault is discovered during the test, the test needs to be paused immediately and all parts of the equipment inspected to ensure their normal operation.For data anomalies, the device needs to be restarted and tested again to ensure the reliability and accuracy of the data.In Shenzhen, a high-tech city, companies usually have complete emergency plans to deal with various emergencies.

8. Make improvements

The final step is to improve and optimize based on the test results.The test results not only help companies understand the air-tightness performance of current products, but also provide a reference for subsequent product development.If the test results show that the air-tightness performance of the product does not meet the standards, the product design needs to be optimized.For specific air tightness problems, it may be necessary to improve sealing materials, adjust structural design, etc.Through continuous optimization and improvement, the air-tightness performance of the product is improved, and the market competitiveness of the product is ultimately enhanced.
