Introduction
Analysis of the core content of the standard
This standard establishes an electronic query structure framework based on XML, which includes a three-level classification system:
| Level | Type | Example |
|---|---|---|
| Non-leaf characterization class | Major categories that can be subdivided | Ball bearings, roller bearings |
| Leaf characterization class | Specific bearing types | Deep groove ball bearings, tapered roller bearings |
| Characteristics | Technical parameters | Seal type, clearance grade |
Key technical characteristics
Typical bearing characteristic system
Take deep groove ball bearing as an example, its characteristic parameters include:
- Seal type: 6 options including double-sided seal/dust cover combination
- Clearance grade: 5 standard grades from CN to C5
- Tolerance grade: 6 precision grades including P0 to P2
Implementation suggestions
| Application scenarios | Implementation points |
|---|---|
| E-commerce platforms | Need to establish a dynamic value range filtering mechanism to exclude incompatible parameter combinations |
| Enterprise ERP | It is recommended to expand the "other" value field to be compatible with non-standard products |
| Data exchange | Use standard XML format to ensure cross-system compatibility |
Technology evolution analysis
Advantages of this standard over traditional paper catalogs:
- Realize multi-dimensional cross-query (such as screening material + precision + clearance at the same time)
- Support standardized description of non-standard parameters
- Provide data architecture foundation for the intelligent selection system
