How to handle the testing report of the sample? What are the scope and standards of testing? Today, the editor of Baijian Testing will take you to understand the specific tests required for the relevant testing business. At the same time, Baijian can also design testing plans based on corresponding testing standards or according to your needs

Testing process

1. Sending samples

2. Checking requirements

3. Targeted quotation

4. Both parties confirm, sign a contract, and start the experiment

5. Completing the experiment: The testing cycle (can be expedited) may change according to the sample and its testing items/methods, and engineers can be consulted

6. Issuing the testing report and providing post service.

Testing items:

Low temperature test, circuit resistance measurement, partial discharge measurement, power frequency withstand voltage test, mechanical test, temperature rise test, humidity test, lightning impulse voltage test, high temperature test, IP code inspection, measurement of main circuit resistance, power frequency voltage test, mechanical operation test at room temperature, mechanical impact test, mechanical characteristic test, creepage distance, design and appearance inspection, voltage test of auxiliary and control circuits, protection level inspection, temperature rise test/continuous current test, additional test of auxiliary and control circuits, AC withstand voltage test, measurement of dielectric loss angle tangent value, use of remote operating devices to check the operation of the operating mechanism, measurement of conductive circuit resistance, and closing time of circuit breakers Check the minimum operating voltage of the closing contactor and opening solenoid of the operating mechanism, determine the leakage current, measure the insulation resistance and DC resistance of the closing contactor and opening solenoid coil, measure the simultaneity of the circuit breaker contacts opening and closing, and measure the parallel resistance, parallel capacitance, and parallel capacitance tg of the arc extinguishing chamber δ (%), Insulation Resistance Measurement
