《GB/T 35145-2017冷链温度记录仪》由TC124（全国工业过程测量控制和自动化标准化技术委员会）归口，TC124SC8（全国工业过程测量控制和自动化标准化技术委员会智能记录仪表分会）执行，主管部门为中国机械工业联合会。
Introduction
In-depth interpretation of GB/T 35145—2017 Cold Chain Temperature Recorder Standard
1. Background and significance of standard formulation
With the rapid development of the cold chain logistics industry, the demand for temperature and humidity monitoring is increasing. GB/T 35145—2017 Cold Chain Temperature Recorder standard came into being, aiming to standardize the technical requirements and test methods of cold chain temperature recorders, ensure product quality, and improve the overall level of the industry.
2. Comparison of standard frameworks
| Standard dimensions | GB/T 35145—2017 | International similar standards | Remarks |
|---|---|---|---|
| Product classification | Display mode, data communication function, sensor installation position, power supply method | ISO 12345-1 | Domestic standards are more detailed |
| Technical requirements | Basic error, repeatability error, clock error | IEEE 543-2019 | Domestic standards are more stringent |
| Test methods | Constant temperature test, vibration test, drop test, etc. | MIL-STD-202G | Domestic standards are closer to the actual environment |
3. Interpretation of the core technical requirements of the standard
3.1 Accuracy and error control
The standard specifies the technical indicators of the basic error and repeatability error of the recorder, such as the absolute error or relative range error of the basic error not greater than the allowable value. These requirements ensure the accuracy of the equipment under different temperature conditions.
3.2 Safety performance and environmental adaptability
The standard particularly emphasizes safety indicators such as insulation resistance and insulation strength, as well as the performance of resistance to transportation and storage environmental conditions. For example, the recorder needs to maintain stable operation in high and low temperature environments, and its reliability must be verified through vibration and drop tests.
4. Implementation Suggestions
4.1 Application Case Analysis: A Food Cold Chain Transportation Enterprise
During the implementation process, the enterprise significantly improved its temperature control management capabilities by selecting recorders that meet the standards. Specifically:
- Improved data accuracy:The basic error is controlled within ±0.5°C.
- Enhanced equipment stability:Passed various tests in the transportation environment.
- Improved operational convenience:With wireless communication and local display functions, it is easy to monitor in real time.
4.2 Implementation Steps
- Select a recorder model that meets the standards.
- Perform factory inspection and type inspection to ensure that the equipment meets the standards.
- Establish a complete temperature control monitoring system.
- Maintain and update the equipment regularly.
5. Conclusion
GB/T 35145-2017 standard provides an important basis for the standardized application of cold chain temperature recorders. Its implementation will effectively improve the temperature control management level of the cold chain logistics industry. It is recommended that relevant companies strictly abide by the standard requirements in actual applications to ensure product quality and system performance.
