The seven fields of a reviewable claim
| Field | Required information | Why it matters |
|---|---|---|
| Identity | Model, version, firmware, battery, motor, impeller and accessories | Small configuration changes can alter performance and document scope. |
| Metric | What was measured, unit and acceptance limit | Prevents mixing RPM, air speed, airflow and pressure. |
| Method | Fixture, distance, position, instrument and procedure | Makes the result understandable and repeatable. |
| Conditions | Mode, battery state, ambient conditions and background noise | Explains variation between tests. |
| Result | Measured value, sample count, variation and pass/fail rule | Separates evidence from promotional wording. |
| Control | Date, report number, reviewer and revision | Supports traceability and change management. |
| Scope | Models, markets and limitations covered | Stops one result being generalized to unrelated products. |
Evidence classes used on this site
Class A
Public controlled evidence
A dated method, result and scope are publicly accessible and can be reviewed without an account.
Class B
Available on request
A controlled document may be reviewed by a qualified buyer under appropriate confidentiality terms.
Class C
Configuration reference
An image or general description supports discovery only; it does not prove a performance or compliance claim.
Certification and transport documents
Verify the applicant or certificate holder, issuing body or laboratory, standard and edition, report or certificate number, issue date, model list, critical components and destination-market relevance. A battery-cell report is not automatically an approval for the complete fan, and a document for one charger or motor should not be generalized to every configuration.
Commercial details such as price, MOQ, availability, lead time, warranty and territory arrangements are time-sensitive. The current written quotation and signed agreement control.
