Introduction
GB/T 5170.2—2017 Standard Overview
GB/T 5170.2—2017 "Test Methods for Environmental Test Equipment Part 2: Temperature Test Equipment" is a key standard for evaluating and verifying the performance of temperature test equipment. This standard specifies in detail the test items, test methods and technical requirements for temperature test equipment to ensure the stability and accuracy of the equipment under different temperature conditions.
Main inspection items
| Serial number | Inspection items |
|---|---|
| 1 | Temperature deviation |
| 2 | Temperature fluctuation |
| 3 | Temperature uniformity |
| 4 | Temperature indication error |
| 5 | Temperature change rate |
| 6 | Average temperature change rate within 5 minutes |
| 7 | Temperature recovery time |
| 8 | Temperature overshoot |
Inspection instruments and requirements
Temperature measurement system: Response time is less than 0.5 seconds, and the maximum allowable error is divided into five levels according to the temperature range.
Anemometer: The induction is not greater than 0.05m/s, used to measure the air flow velocity inside the equipment.
Sound level meter: The maximum allowable error does not exceed ±1dB, used to evaluate the noise level of the equipment.
Comparison of standard frameworks
| Dimensions | GB/T 5170.2—2017 | Old version of the standard GB/T 5170.2—2008 |
|---|---|---|
| Scope | Applicable to GB/T 2423 series temperature test equipment inspection | Only for temperature test equipment for electrical and electronic products |
| Technical requirements | Detailed instrument response time and error range | No detailed technical parameters |
| Test methods | Reorganized and added verification steps | The test method is relatively simple |
Implementation Recommendations
1. When selecting a test instrument, ensure that its response time and measurement accuracy meet the standard requirements.
2. For complex equipment, it is recommended to conduct additional tests under load conditions and record relevant data for reference.
3. Regularly calibrate the test instrument to ensure the accuracy of the measurement system.
4. It is recommended to establish a detailed test report template to ensure that all necessary information is fully recorded.
