Introduction
Analysis of the core content of the standard
The GB/T40412-2021 standard builds a complete technical system for military and civilian general resource data carriers, mainly including the identification specifications of three types of carriers: one-dimensional code, two-dimensional code and radio frequency tag. The standard innovatively proposes two types of data structures (the basic structure of commodity circulation code and the ISO/IEC15434 encapsulation structure), and provides a detailed coding comparison table and implementation examples in the form of an appendix.
Comparison of key technologies
| Carrier type | Applicable data structure | Core standard | Storage capacity |
|---|---|---|---|
| One-dimensional code | Class I/Class II | GB/T15425, GB12904 | ≤30 characters |
| Two-dimensional code | Mainly Class II | GB/T21049, GB/T18284 | ≤2953 bytes |
| RFID tag | Second category priority | GB/T29768, ISO/IEC18000-63 | ≥256bit |
Implementation points
Military medical device identification case
Take Zhejiang Youyi Medical Devices as an example, when the second category data structure is used:
- The item unique identification area writes DSFID=03h and AFI=08h
- The user area stores maintenance records (A075-A077) and life indicators (A072-A073)
- The QR code symbol level must meet the 1.5/06/660 detection requirements
Special requirements for military applications
- Dangerous goods must be equipped with an application attribute indicator of 1Fh=1
- Special identifiers (A000-A083) must give priority to the 200 extended fields defined by the military
- RFID tags must pass the 7mm/min rain test and the 95% humidity test
