Certification Reports

Photobiological Safety

EN 62471:2008 — Exempt Group

Report No. YDL061092366C

The report classifies the tested QZ-808 production samples in the Exempt Group for the evaluated photobiological hazard categories.

Electromagnetic Emissions

FCC Part 15 Subpart B — Class B Pass

Report No. YDL061092365C

The tested samples passed the applicable Class B emissions requirements for consumer electronic equipment.

Electromagnetic Compatibility

CE EMC — Pass

Report No. YDL061092361C

The report covers applicable electromagnetic compatibility testing, including emissions and immunity-related requirements.

Restricted Substances

RoHS — All Below Limit

Report No. YDL061092362C

The tested component samples were reported below the applicable limits for the restricted substances evaluated under the report.

Wavelength Verification

Measured 660nm + 850nm Output

Spectral measurements reported for tested QZ-808 samples confirm peak output ranges close to the specified 660nm red and 850nm near-infrared wavelengths.

660nmRed Light

Measured peak range: 660.4–662.3nm.

850nmNear-Infrared Light

Measured peak range: 852.3–853.5nm.

What “Exempt Group” Means

EN 62471 classifies optical radiation risk from lamps and lamp systems. “Exempt Group” is the lowest risk classification under the standard for the conditions evaluated in the laboratory report.

Important: this classification describes the tested device samples under the standard. It is not a medical efficacy claim and does not replace the product instructions or normal-use precautions.

About the Testing Laboratory

Ningbo Youdeli Testing Technology Service Co., Ltd.

The reports referenced on this page were issued for QZ-808 production samples by this independent testing laboratory.

Scope of These Results

Testing results relate to the specific QZ-808 production samples evaluated in the referenced reports. Individual production units may vary. These reports verify the tested characteristics and compliance results described above; they do not establish that NASHIMPRO commissioned the testing, and they do not by themselves prove treatment outcomes for any medical condition.
