Analysis of High Temperature Resistance Test for Electronic and Electrical Products

In the research and production process of electronic and electrical products, high temperature resistance testing is an important testing step. Through high-temperature resistance testing, the performance stability and safety of the product in high-temperature environments can be evaluated, ensuring that the product can work stably and reliably in practical use. This article will introduce the high temperature resistance test of electronic and electrical products, including standards, application process, and testing items.

standard

The standards for high temperature resistance testing usually follow the relevant standards of the International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC). Among them, commonly used standards include:

1. ISO 16750-4: Environmental testing for automotive electronic products, including high-temperature testing.

2. IEC 60068-2-2: Basic environmental testing standards for electronic and electrical products, including high-temperature testing.

These standards specify the specific requirements and testing methods for high temperature resistance testing to ensure accuracy and comparability.

Application process

Conducting a high temperature resistance test requires a series of application processes, including the following steps:

1. Determine test standards: Firstly, it is necessary to determine the applicable test standards, such as selecting the corresponding ISO or IEC standards based on product type and market requirements.

2. Select testing institution: Next, choose a qualified and reputable testing institution to conduct the experiment. Ensure that the testing agency has relevant certifications and equipment to conduct testing in accordance with standard requirements.

3. Submit application: Submit a test application to the testing agency, including product information, test standards, test requirements, and other content.

4. Sample preparation: According to the requirements of the testing agency, prepare samples that meet the requirements and ensure that the quantity and quality of the samples meet the standard requirements.

5. Conduct experiments: Under the guidance of the testing agency, conduct high-temperature resistance tests and ensure that operations are carried out in accordance with standard requirements.

6. Obtain report: After completing the experiment, the testing agency will issue a test report, which includes information such as the test method, results, and conclusions.

Test items

The high temperature resistance test usually includes the following testing items:

1. Temperature cycling test: Conduct cyclic changes within the specified temperature range to evaluate the performance of the product in temperature changing environments.

2. Constant temperature test: Place the product in a constant high temperature environment to evaluate its performance stability under prolonged high temperatures.

3. Insulation performance test: Test the insulation performance of the product in high temperature environments to ensure that the product will not experience insulation faults in high temperature environments.

4. Electrical performance testing: Test the electrical performance of the product in a high-temperature environment, including the stability and safety of parameters such as current and voltage.

Through the above testing items, the performance of the product in high-temperature environments can be comprehensively evaluated, providing important references for product design and production.The high temperature resistance test of electronic and electrical products is an important link to ensure product quality and safety. Following relevant standards, strictly following the application process, and conducting comprehensive testing projects can ensure the stability and reliability of the product in high-temperature environments, providing strong support for the market promotion and application of the product.
