PROCUREMENT EVIDENCE GUIDES
Common Chinese-report questions,
organised by equipment family.
Use these starting points to identify which target clauses and test evidence to supply. They are navigation aids, not substitutes for the governing standard or project specification.
TRANSFORMERSGB/T 1094 and IEC 60076 evidence
Check whether ratings, frequency, insulation levels, temperature rise, losses, sound level and special dry-type classifications are supported for the offered unit.
- Type-test applicability
- Offered unit versus tested unit
- Project environmental classes
Review transformer evidence →MV SWITCHGEARGB 3906 and IEC 62271 evidence
Separate basic ratings from project-specific service continuity, internal arc classification, compartment accessibility and test configuration.
- IAC and LSC evidence
- Short-circuit duty
- Accessories and interlocks
Review switchgear evidence →LV ASSEMBLIESGB/T 7251 and IEC 61439 evidence
Verify the assembly design, short-circuit strength, temperature-rise limits and form of separation instead of relying only on component certificates.
- Design verification route
- Assembly versus components
- Declared operating conditions
Review LV assembly evidence →BUYER CHECKLISTHow to read a Chinese type-test report
Identify the report owner, tested model, referenced edition, test laboratory, page continuity and the relationship between the tested and offered configurations.
- Scope and traceability
- Missing versus failed evidence
- Questions for the manufacturer
