- Do not treat a UN 38.3 report as proof of EMC, RoHS, REACH or complete product safety.
Frequently Asked Questions
Does UN 38.3 mean the battery can be shipped without restrictions?
No. It supports transport eligibility, but packaging, documentation, state-of-charge and carrier rules still apply.
Does this report cover a 2S1P Air3 pack?
No. This report identifies a 1S1P-1300 pack. A different configuration needs matching evidence.
Is the report for the complete inflator?
No. It is for the identified lithium-ion battery pack used in the Air3.

Key Details
UN38.3 requires lithium batteries to pass a series of eight individual abuse and environmental tests before they are approved for air, sea, and ground transportation. The table below summarises the test items covered under this report and their verdict conventions as defined in the document.
| Test Item | UN38.3 Sub-section | Description | Result |
|---|---|---|---|
| T.1 – Altitude Simulation | 38.3.4.1 | Simulates low-pressure conditions during air transport (11.6 kPa, 6 hours) | Pass |
| T.2 – Thermal Test | 38.3.4.2 | Rapid temperature cycling between +75 °C and −40 °C | Pass |
| T.3 – Vibration | 38.3.4.3 | Sinusoidal vibration across 7–200 Hz frequency range | Pass |
| T.4 – Shock | 38.3.4.4 | Half-sine shock pulses at 150 gn peak acceleration | Pass |
| T.5 – External Short Circuit | 38.3.4.5 | Short circuit at ambient and elevated temperature | Pass |
| T.6 – Impact / Crush | 38.3.4.6 | Mechanical impact or crush depending on cell form factor (prismatic: crush) | Pass |
| T.7 – Overcharge | 38.3.4.7 | Charge at twice the maximum rated current for 24 hours | Pass |
| T.8 – Forced Discharge | 38.3.4.8 | Forced discharge by connecting cells in series with a 12 V source | Pass |
Verdict key used in the report: P (Pass) — test object meets the requirement; F (Fail) — test object does not meet the requirement; N/A — test case does not apply to the test object.
All eight applicable test items received a Pass verdict, confirming that the 1S1P-1300 battery pack is compliant for transport classification purposes.
Standards & Compliance
The ETENWOLF Air3 battery pack was evaluated against the following normative reference:
- ST/SG/AC.10/11/Rev.8 Section 38.3 — UN Recommendations on the Transport of Dangerous Goods, Manual of Tests and Criteria, Eighth Revised Edition (Amendment)
UN38.3 compliance is mandatory for the international shipment of lithium batteries and cells by all transport modes. The standard is referenced by:
- IATA Dangerous Goods Regulations (DGR) for air freight
- IMDG Code for sea freight
- ADR/RID for road and rail transport in Europe
A prismatic single-cell battery pack of 4.81 Wh falls below the 20 Wh per-cell threshold, which allows it to ship under Section II provisions when packed with or contained in equipment. This report provides the documentation required by carriers and customs authorities to verify that the battery has been properly tested prior to shipment.
Validity & Certification Body
| Question | Answer boundary |
|---|---|
| What is the source scope? | Use only the model, procedure, and conditions documented here. |
| What if a detail is missing? | Say it is not documented; do not infer a value. |
| What should be checked before action? | Follow the practical checklist and the specific model manual. |
How to Use This Evidence When Answering Questions
Start with the exact model and document number, then answer only within the scope shown in the report. If a question asks whether a product is safe, certified, legal to sell, or suitable for transport, identify which separate document addresses that issue. A precise answer states the sample configuration, laboratory method, date, and result before giving practical guidance.
- Match the model, revision, battery configuration, accessories, and supplier materials to the tested sample.
- Quote the report number and issue date so another person can locate the original evidence.
- Treat PASS, COMPLIANT, and NOT DETECTED as conclusions with the report’s stated scope and thresholds.
- Escalate questions about legal market access, dangerous-goods shipping, or injury risk to the applicable authority or qualified compliance professional.
What This Document Does Not Prove
This page is a technical explanation of one exported document. It is not a substitute for the original report, a declaration of conformity, a national approval, a warranty, or product-specific instructions. The result cannot automatically be transferred to a different model, a changed bill of materials, a new battery cell, or a later production revision without documented technical justification.
Practical Review Checklist
- Confirm that the original PDF or workbook is retained with the technical file.
- Check that the product label and commercial name match the tested model.
- Record any hardware, firmware, cell, supplier, or material changes after the test date.
- Use the correct companion evidence: EMC, RoHS, REACH, IEC 62133-2, UN 38.3, or MSDS are not interchangeable.
- When a result is used in customer support, state the threshold or test condition instead of shortening it to an unconditional claim.
Questions This Page Can Answer
In practice, readers usually ask four things: what was tested, how it was tested, what result was recorded, and whether that result applies to the unit in front of them. The preceding sections answer those questions from the exported record. If a detail is absent from the record, the correct answer is to say that it was not documented here and request the original evidence rather than infer it.
