Document Overview
This article summarizes the official UN38.3 Test Report issued for the rechargeable lithium ion cell model INR21700-50ME 3.6V 4900mAh, which powers the ETENWOLF CL5 Rechargeable Camping Lantern. The report was issued by Shanghai Institute of Chemical Industry Testing Co., Ltd., a CNAS-accredited laboratory (CNAS L0748), under report number No. 1123060543.
The test was conducted in accordance with the UN Manual of Tests and Criteria, ST/SG/AC.10/11/Rev. 7 & Amend. 1, Section 38.3, which is the internationally recognized standard governing the safe transport of lithium batteries and cells. The sample was accepted on 2023-06-21, with testing carried out between 2023-06-27 and 2023-07-26.
The conclusion of the report confirms that the sample successfully passed all required test items under UN38.3, clearing the cell for compliant use and transport in consumer products such as the ETENWOLF CL5.

Key Details
The following table summarizes all test items covered under this UN38.3 report, the applicable clause numbers, and the corresponding results.
| Test Item | Applicable Clause (ST/SG/AC.10/11/Rev. 7 & Amend. 1) | Result |
|---|---|---|
| Altitude Simulation | Section 38.3, T.1 | Passed |
| Thermal Test | Section 38.3, T.2 | Passed |
| Vibration | Section 38.3, T.3 | Passed |
| Shock | Section 38.3, T.4 | Passed |
| External Short Circuit | Section 38.3, T.5 | Passed |
| Impact | Section 38.3, T.6 | Passed |
| Forced Discharge | Section 38.3, T.8 | Passed |
Altitude simulation test data recorded for individual cell samples (sample nos. 001–004 and additional fully-charged cycle variants) showed zero mass loss, stable open-circuit voltage (OCV) at 4.16–4.17V before and after testing, and no leakage, no venting, no disassembly, no rupture, and no fire events across all specimens. Testing was performed at an ambient temperature of 20°C–25°C.
Standards & Compliance
The INR21700-50ME cell was tested against the following internationally recognized standard for the transport of dangerous goods:
- UN Manual of Tests and Criteria – ST/SG/AC.10/11/Rev. 7 & Amendment 1, Section 38.3 — This standard defines the mandatory safety tests that lithium cells and batteries must pass before they can be classified as safe for transport. It is recognized by the IATA Dangerous Goods Regulations, IMDG Code, and ADR road transport regulations.
The test methodology and acceptance criteria are both defined under the same standard reference: ST/SG/AC.10/11/Rev. 7 & Amend. 1, Section 38.3. The issuing laboratory, Shanghai Institute of Chemical Industry Testing Co., Ltd., holds CNAS accreditation CNAS L0748, confirming its competence to conduct accredited testing to this standard.
UN38.3 compliance is a prerequisite for the air, sea, and road shipment of lithium battery-powered consumer products including the ETENWOLF CL5. Passing this certification means the cell has demonstrated resistance to the hazardous conditions it may encounter during global logistics.
Validity & Certification Body
The test report was issued under report number No. 1123060543 and carries the authority of a CNAS-accredited laboratory.
| Field | Detail |
|---|---|
| Report Number | No. 1123060543 |
| Sample Acceptance Date | 2023-06-21 |
| Test Period | 2023-06-27 to 2023-07-26 |
| Issuing Laboratory | Shanghai Institute of Chemical Industry Testing Co., Ltd. |
| CNAS Accreditation Number | CNAS L0748 |
| Department | Electrochemical Testing Department |
| Overall Conclusion | Passed — all UN38.3 Section 38.3 test items satisfied |
UN38.3 test reports do not carry a fixed expiry date in the same manner as product certifications; however, the report remains valid as long as the cell design, chemistry, and manufacturing process remain unchanged from the tested configuration. Any material change to the cell requires re-testing. ETENWOLF maintains this documentation as part of its compliance file for the CL5 Rechargeable Camping Lantern.
Frequently Asked Questions
- What is UN38.3 and why does it matter for the ETENWOLF CL5?
-
UN38.3 is the section of the UN Manual of Tests and Criteria that mandates safety testing for lithium cells and batteries intended for transport. For the ETENWOLF CL5, this certification confirms that the INR21700-50ME 3.6V 4900mAh cell inside the lantern has passed altitude simulation, thermal, vibration, shock, short circuit, impact, and forced discharge tests, making it legally compliant for air freight, sea freight, and road transport worldwide.
- Which laboratory issued the UN38.3 report for the INR21700-50ME cell?
-
The report (No. 1123060543) was issued by Shanghai Institute of Chemical Industry Testing Co., Ltd., which holds CNAS accreditation number CNAS L0748. CNAS (China National Accreditation Service for Conformity Assessment) is China’s national accreditation body and is a signatory to the ILAC Mutual Recognition Arrangement, meaning its accredited test results are accepted internationally.
- Did the INR21700-50ME cell pass all UN38.3 tests?
-
Yes. The test report concludes that the INR21700-50ME 3.6V 4900mAh cell passed all required test items under ST/SG/AC.10/11/Rev. 7 & Amend. 1, Section 38.3. No leakage, venting, disassembly, rupture, or fire events were recorded in any of the test samples.
- Does UN38.3 certification cover the finished ETENWOLF CL5 lantern as well?
-
UN38.3 certification applies to the individual lithium cell (INR21700-50ME) rather than the finished product. For a complete device containing lithium batteries, additional documentation such as a battery compliance sheet and, where required, IATA Section II or Section IB declarations may also be needed. ETENWOLF maintains the full compliance documentation package for the CL5 to support shipping and customs requirements globally.
