Introduction
Analysis of the Standard's Core Content
RB/T 186-2017 is my country's first specialized standard for proficiency testing in qualitative testing, filling a gap in qualitative proficiency testing evaluation methods both domestically and internationally. The standard applies to proficiency testing activities in non-numerical testing areas such as microbiological testing, species identification, and medical grading.
Comparison of key technical elements
| Evaluation dimensions | Quantitative proficiency testing | Qualitative proficiency testing |
|---|---|---|
| Result type | Numerical result | Descriptive judgment (negative/positive, grade, etc.) |
| Determination of designated value | Metrological traceability | Expert consensus (≥80% consistency) |
| Source of difference | Instrument accuracy, method bias | Feature identification, logical reasoning |
Detailed explanation of implementation points
1. Requirements for item preparation
The standard requires that qualitative proficiency testing items must pass consistency testing and stability testing:
- Natural samples: Require joint calibration with multiple methods (such as standard microbial strains)
- Artificially prepared samples: Require verification of matrix interference (such as simulated samples for medical testing)
2. Method for establishing designated values
Case: In the identification of animal and plant quarantine species, the standard requires that designated values should be obtained through authoritative determination by expert laboratories or comparison with standard charts, and complete traceability records must be retained.
Industry application suggestions
- Medical testing field: A double-blind sample design is recommended for conformity judgment projects such as blood typing.
- Forensic identification field: An expert arbitration mechanism should be established for projects with high subjectivity, such as note identification.
- Microbiological testing: Participants are required to submit characteristic trait observation records as process evidence.
Background of standard evolution
The formulation of this standard is based on my country's accumulated practical experience in entry-exit inspection and quarantine, medical diagnosis and other fields. For the first time, it systematically proposes three types of evaluation for qualitative proficiency testing:
- Nomenclature (classification) determination
- Sequencing (grading) determination
- Conformity determination
