Introduction
Analysis of the core framework of the standard
| Classification dimensions | Testing laboratories | Calibration laboratories |
|---|---|---|
| Number of first-level fields | 14 categories (01-14) | 11 categories (60-70) |
| Classification methods | Mainly surface classification method (by subject/product) | Mainly line classification method (by metrology major) |
| Typical fields | Biology (01), medical devices (08) | Geometric quantity (60), radio (65) |
| Coding structure | 6 digits (XX XX XX) three-level subdivision | |
Detailed explanation of key areas of testing laboratories
Typical classification in the electrical field (04)
Using the surface classification method to divide into 32 subcategories:
- General environmental testing (0401): 16 tests including salt spray and vibration
- Photovoltaic products (0421): 6 subcategories including components and inverters
- Battery testing (0404): Covers 5 categories including lithium-ion/lead-acid
Key Points of Calibration Laboratory Technology
Equipment Case for Geometric Measurement (60)
| Secondary Field | Typical Instruments | Calibration Parameters |
|---|---|---|
| Line Grain (6001) | Laser Interferometer | 633nm Wavelength Stability |
| Engineering Parameters (6006) | Coordinate Measuring Machine | Spatial Dimension Error |
| Gear Measurement (6005) | Coordinate Measuring Machine | Spatial Dimension Error |
| Gear Measurement (6005) | Involute template | Tooth profile deviation |
Standard implementation recommendations
- Capability declaration: Select the last code according to the three-level classification (such as 010101 Conventional microorganisms in food)
- Cross-domain processing: Electromagnetic compatibility of medical devices requires simultaneous declaration of 08 and 12 fields
- Dynamic expansion: Use "99" code to handle emerging technologies (such as 0213 new fuel additives)
Technology evolution analysis
Main changes compared with the previous version:
- Added Software products and information security (14) independent field
- Refine new energy vehicle testing (0426 Motors and electric pumps)
- IoT Device Calibration Supplement (6506 Wireless Communication Test)
