National standard for high temperature aging test
The high-temperature aging test simulates the performance changes and failures of the product in a certain high-temperature environment and within a certain period of time to evaluate the weather resistance and reliability of the product. In order to ensure the accuracy and reliability of the test, the high-temperature aging test needs to follow certain national standards.
First, the test conditions.
The test conditions of the high-temperature aging test include temperature, humidity, light, etc. In the national standard, there are clear provisions on the test conditions. For example, the temperature range should be between 40 -70, the humidity range should be between 40%-85%, and the light intensity should be 05w/m²-4.5w m between. The setting of these conditions should be determined according to the actual use environment of the product to ensure the accuracy and reliability of the test results.
2. Test samples.
The test samples of the high-temperature aging test should be representative and reflect the actual use of the product. In the national standard, there are clear provisions on the selection and preparation of test samples. For example, test samples should be randomly selected from the products on the production line, in quantities of no less than 5. When preparing the test sample, the product should be kept in its original state, and no treatment should be carried out that may affect the test results.
3. Test procedures.
The test procedure of the high-temperature aging test includes the preparation before the test, the monitoring during the test and the treatment after the test. In the national standards, there are clear provisions on the test procedures. For example, test samples should be visually inspected and tested for performance prior to testing. During the test, the test samples should be checked and recorded regularly. After the test, the test sample should be tested for performance and visual inspection, and its aging should be evaluated.
4. Data processing and analysis.
The data processing and analysis of the high-temperature aging test is a very important part of the test. In the national standards, there are clear provisions on the methods of data processing and analysis. For example, data should be processed and analysed using appropriate statistical methods to assess product performance changes and failures. At the same time, the test results should be interpreted and evaluated according to the actual use of the product.
5. Test report.
After the high-temperature aging test, a test report should be prepared to record and summarize the process and results of the test in detail. In the national standard, there are clear provisions on the content of the test report. For example, the test report should include the purpose of the test, the test conditions, the test samples, the test procedures, the data processing and analysis, the test conclusions, etc. At the same time, the test report should be clear, accurate, and complete, and be able to provide valuable information and suggestions to readers.
The national standard for high temperature aging test is formulated to ensure the accuracy and reliability of the test. In the process of testing, the requirements of national standards should be followed, and every link should be carefully implemented to ensure the accuracy and reliability of the test results. At the same time, the test results should be interpreted and evaluated according to the actual use of the product, so as to provide strong support for the optimization and improvement of the product.
