Introduction
Interpretation of the core content of the standard
This standard replaces GB/T16759-2017, and for the first time includes services in the scope of comparative testing. It adopts the ISO/IEC Guide46:2017 international guide framework, and focuses on the following specifications:
| Dimensions | Requirements of this standard | Differences between international standards |
|---|---|---|
| Scope of application | Product + Service | Product only |
| Definition of terms | Modify 3 key terms | Keep the original expression |
| Reference to standards | GB/T27000 replaces ISO17000 | Directly quotes ISO standards |
Analysis of implementation points
Sampling principles
Emphasis on market availability and randomness, requirements:
- The sample status must be consistent with what consumers actually obtain
- Service sampling needs to consider industry characteristics (such as fast food vs. financial services)
- When publishing results, it is necessary to ensure that the product is still on sale
Feature selection
Priority should be given to 12 core features that affect consumer decisions:
Case: The comparative test of household appliances needs to test mandatory standard indicators such as energy consumption (GB21455) and noise (GB19606), as well as non-standard characteristics such as APP control convenience.
Difference from related activities
| Activity type | Testing purpose | Result form |
|---|---|---|
| Comparative test | Quality difference analysis | Grading and sorting |
| Market supervision | Compliance verification | Pass/fail |
| Quality control | Production stability | Process parameters |
Laboratory implementation recommendations
- Prioritize the use of laboratories accredited by GB/T27025
- Non-standard methods require method validation
- Major risk results must be reported to the manufacturer within 24 hours
- Service testing should be combined with special methods such as mystery shoppers
Note: This standard is not applicable to the identification of counterfeit goods. Related activities should be carried out in accordance with ISO22383:2020
