2Expert Interpretation
Interpretation of GB/T 35401-2017 "General Technical Specifications for Mobile Laboratories for Groundwater Testing", covering the background of standard formulation, technical requirements, laboratory cabin design and instrument equipment configuration, and providing professional analysis and implementation suggestions.
Foreword
GB/T 35401-2017 "General Technical Specifications for Mobile Laboratories for Groundwater Testing" was proposed and managed by the National Mobile Laboratory Standardization Technical Committee, and the main drafting units include Qingdao Jiaming Measurement and Control Technology Co., Ltd., Chinese Academy of Environmental Sciences, etc. The formulation of the standard aims to standardize the design, manufacture and use of mobile laboratories for groundwater testing to ensure their reliability and functionality in different environments.Comparison of standard frameworks
| Chapter | Technical requirements | Test methods | Scope of application |
|---|---|---|---|
| 4.1 | Basic requirements (working environment, vehicle selection) | Overall test and functional verification | Applicable to land use |
| 4.3 | Experimental cabin design (rationality of layout, interior materials) | Partition inspection and safety assessment | Laboratory internal facilities requirements |
| 5.6 | Instrument and equipment configuration | Equipment performance test and data analysis | Technical parameters of testing equipment |
Technical requirements interpretation
4.1 Basic requirements
The working environment of the mobile laboratory must comply with the provisions of GB/T 29600-2012 on temperature and humidity control to ensure the accuracy of the experimental data. At the same time, the laboratory should be equipped with a satellite positioning system and a driving record system to meet the needs of field operations.
4.3 Experimental cabin design
The interior materials of the experimental cabin must comply with the provisions of GB/T 29471-2012 to ensure environmental protection and durability. In addition, the laboratory should be equipped with ultraviolet germicidal lamps (in accordance with GB19258-2012) to ensure the safety of the internal environment of the laboratory.
4.6 Instrument and equipment requirements
The instruments and equipment of the mobile laboratory must be automated, intelligent and portable. For example, the application of high-end equipment such as ion chromatograph and gas chromatography-mass spectrometry (GC-MAS) has significantly improved the efficiency and accuracy of groundwater detection.
Implementation suggestions
- Strictly select carriers and laboratory cabins in accordance with the standards to ensure that they meet the restrictions on external dimensions and axle loads in GB/T 1589-2016.
- When selecting instruments and equipment, give priority to products with modular design to improve the maintainability and scalability of the laboratory.
- Strengthen personnel training to ensure that operators are familiar with the safety requirements and emergency response procedures of mobile laboratories.
