Sample quantities were in accordance with Table 1 of IEC 62133-2:2017 and IEC 62133-2:2017/AMD1:2021. The overall conclusion is that the samples comply with the requirements of IEC 62133-2:2017 and IEC 62133-2:2017/AMD1:2021.
The report includes two attachments: Attachment No. 1 — 3 pages of Republic of Korea National Differences; Attachment No. 2 — 5 pages of Photo Documentation.
Regarding measurement uncertainty, no decision rule is specified by the IEC standard. Decisions on conformity were made without applying measurement uncertainty, using the simple acceptance (accuracy method) decision rule. Uncertainty calculations are on file with the NCB and testing laboratory.
Standards & Compliance
The ETENWOLF S1 battery pack was evaluated against the following standards and frameworks:
| Standard | Scope |
|---|---|
| IEC 62133-2:2017 | Safety requirements for portable sealed secondary lithium cells and batteries — Part 2: Lithium systems |
| IEC 62133-2:2017/AMD1:2021 | Amendment 1 to IEC 62133-2:2017, updating safety test requirements for lithium systems |
| EN 62133-2:2017/A1:2021 | European harmonized equivalent; compliance confirmed for CENELEC member countries |
| BS EN 62133-2:2017+A1:2021 | British Standard equivalent; compliance confirmed |
| KR National Differences | Republic of Korea national differences evaluated (see Attachment No. 1) |
The test was executed under the IECEE CB Scheme, an international mutual recognition framework that allows a single test report to support certification in multiple member countries. The TRF template used was IECEE OD-2020-F1:2024, Ed.1.7, with the TRF form originated by DEKRA Certification B.V.
National differences were evaluated for CENELEC member countries (EN and BS EN compliance confirmed) and for the Republic of Korea (KR). No additional IECEE member countries with unpublished national differences were identified as not applicable.

Frequently Asked Questions
- What does the CB Test Report 085-28225577-000 certify for the ETENWOLF S1?
- The report confirms that the lithium-ion battery pack (model 2S1P-2600, rated 7.4 V / 2600 mAh) inside the ETENWOLF S1 portable tire inflator passed all required safety tests under IEC 62133-2:2017 and IEC 62133-2:2017/AMD1:2021. Tests covered short circuit, thermal abuse, crush, overcharge, forced discharge, vibration, mechanical shock, and more.
- Which countries accept this CB Test Report?
- The IECEE CB Scheme is an international mutual recognition arrangement. This report supports certification in all IECEE member countries. Compliance with EN 62133-2:2017/A1:2021 and BS EN 62133-2:2017+A1:2021 was confirmed for CENELEC member countries (covering most of Europe), and Republic of Korea (KR) national differences were also evaluated.
- Who conducted the testing for the ETENWOLF S1 battery pack?
- Testing was performed by TÜV SÜD Certification and Testing (China) Co., Ltd. Shenzhen Branch, under the oversight of NCB TÜV SÜD PSB Pte. Ltd. in Singapore. The report was tested by West Li (Project Handler) and approved by Saga Shen (Project Reviewer).
- Is the IEC 62133-2 CB certificate the same as a UN38.3 transport certification?
- No. IEC 62133-2 covers electrical safety for portable lithium battery use, while UN 38.3 covers transport safety requirements for lithium batteries (vibration, altitude simulation, thermal, shock, etc.). The ETENWOLF S1 may hold separate UN38.3 certification for shipping compliance.
