GB/T 39006-2020 in English

Standard Background and Technological Evolution

With the widespread application of industrial robots in fields such as automobile manufacturing and electronic assembly, their environmental adaptability has become a key quality indicator. GB/T39006-2020 systematically regulates the reliability requirements of industrial robots under extreme climatic conditions for the first time, filling the gap in domestic standards in this field.

Comparison of core test requirements

Detailed explanation of key test methods

6.3.2 High temperature operation test

After the controller and operator reach temperature stability, continue to operate at Tmax±2℃ for 4 hours. It is recommended to use the step temperature increase method, and the temperature increase should not exceed 5℃ every 10 minutes.

6.6.1 Salt spray test

Use 5% sodium chloride solution, and the collector is required to have a salt spray deposition of 1.0-2.0mL per hour. For key components such as harmonic reducer, additional inspection of grease performance changes is required.

Implementation suggestions

1. Pretreatment: All tests must be balanced in an environment at 25℃±5℃ for 24 hours
2. Test sequence: It is recommended to conduct the test in the order of temperature and humidity → mechanical stress → corrosion test
3. Failure judgment: If the IP level drops and the repeat positioning accuracy exceeds ±0.1mm, it will be judged as unqualified
