Accurate temperature control is crucial in the operation of clean rooms (areas), which directly affects the quality of products and the safety of the production environment. According to the needs of temperature testing, the following are the specifications for clean room temperature testing, including test types, methods, implementation requirements and recording standards.
Test types
The Temperature detection of clean rooms is divided into two categories:
1. General temperature test
This test is applicable to temperature monitoring of clean rooms (areas) in "empty" conditions, mainly used to confirm the basic performance and operating status of the system.
2. Functional temperature test
This test will be used when the clean room (area) needs to strictly control the temperature accuracy, or when the builder requires testing under specific "static" or "dynamic" conditions. The purpose of the functional temperature test is to ensure the temperature stability and consistency of the clean room under specific process requirements.
Test tools
Temperature testing can be performed using a variety of instruments, and commonly used equipment includes:
1. Glass thermometer
2. Resistance temperature detection device
3. Digital thermometer
Choosing the right measuring tool can improve the accuracy and reliability of the test.
Preparation before testing
Before conducting a temperature test, the following preparations must be completed:
1. Airflow uniformity test
Ensure that the air flow in the clean room (area) is uniform to avoid local temperature differences affecting the test results.
2. Continuous operation
The purification Air conditioning system should run continuously for at least 24 hours to ensure that the system is stable and achieve the expected temperature control effect.
General temperature test requirements
The implementation requirements of general temperature testing are as follows:
1. Measurement point setting
Set a measurement point in each temperature control area or each room, and the height of the measurement point should be consistent with the height of the work surface.
2. Measurement time
The measurement time should be no less than 1 hour, and a reading should be taken at least every 6 minutes, and records should be made after the reading is stable.
Functional temperature test requirements
The implementation requirements of functional temperature test are more stringent:
1. Grid measurement points
The clean work area should be divided into grids of equal area, and the area of each grid should not exceed 100 square meters, or determined according to the negotiation of the construction party. Each grid should have at least one measurement point, and each room should have at least two measurement points.
2. Measurement point height
The height of the measurement point should be the height of the working surface, and the distance from the ceiling, wall and floor of the clean room (area) should be no less than 300mm to avoid interference from factors such as heat sources.
3. Measurement time
It should also be no less than 1 hour, and a reading should be taken at least every 6 minutes, and records should be made after the reading is stable.
By strictly following the above temperature detection specifications, it can effectively ensure that the temperature in the clean room (area) is controlled within the set range, ensuring the smooth progress of the production process and the quality and safety of the product. Regular temperature testing and recording will provide strong support for the long-term stable operation of the clean room.
