Standards & Compliance
The battery pack was tested and found to be in full conformity with the following international safety standards:
Primary Standards:
- IEC 62133-2:2017 – Secondary cells and batteries containing alkaline or other non-acid electrolytes – Safety requirements for portable sealed secondary cells, and for batteries made from them, for use in portable applications – Part 2: Lithium systems
- IEC 62133-2:2017/AMD1:2021 – Amendment 1 to IEC 62133-2:2017, incorporating updated safety requirements and test procedures
Regional Harmonized Standards:
- EN 62133-2:2017/A1:2021 – European harmonized version of IEC 62133-2 with regional modifications
Testing Scope: The certification testing program evaluated mechanical safety, electrical safety, thermal performance, and abuse condition resistance. Tests included external short circuit, thermal abuse, crush, impact, vibration, shock, and overcharge protection verification.
National Differences Evaluated: The product has been assessed against specific national requirements for South Korea (KR) and Great Britain (GB), ensuring compliance with local market regulations in addition to the base IEC standards.
Validity & Certification Body
Issuing Authority: TÜV SÜD PSB Pte Ltd
TÜV SÜD PSB is an accredited National Certification Body (NCB) authorized to issue CB Test Certificates under the IECEE CB Scheme. The organization operates from its Singapore facility at 15 International Business Park, TÜV SÜD @ IBP, Singapore 609937.
Authorized Signatory: Kevin Zou, on behalf of TÜV SÜD PSB Pte Ltd
Certificate Validity: CB Test Certificates remain valid as long as the product construction, manufacturing processes, and applicable standards remain unchanged. Any modifications to the battery design, cell chemistry, protection circuitry, or manufacturing location may require re-evaluation and issuance of a new certificate.
Supporting Documentation: This certificate is accompanied by Test Report No. 085-28225577-000, which provides detailed test results, methodology, and technical findings. The test report forms an integral part of this certification and must be presented together with the certificate for market approval purposes.
CB Scheme Recognition: This certificate is recognized by over 50 countries participating in the IECEE CB Scheme, facilitating streamlined market access for the ETENWOLF S1 battery system across international markets.
Frequently Asked Questions
Q: What is a CB Test Certificate and why is it important?
A: A CB Test Certificate is an internationally recognized document issued under the IECEE CB Scheme that confirms a product meets IEC safety standards. For the S1 battery pack, this certificate enables market access across 50+ countries without requiring duplicate testing, significantly reducing time-to-market and certification costs for global distribution.
Q: Does this certificate cover the entire ETENWOLF S1 tire inflator?
A: No, this specific CB certificate (SG PSB-BT-07583) covers only the lithium-ion battery pack component (model 2S1P-2600) used within the S1 inflator. The complete product typically requires additional certifications for the motor assembly, charging circuitry, and overall system safety compliance.
Q: What does compliance with IEC 62133-2 mean for battery safety?
A: IEC 62133-2 compliance confirms the battery has passed rigorous safety tests including external short circuit protection, thermal abuse resistance, mechanical stress tests (crush, impact, vibration), and overcharge protection. This ensures the battery pack can safely withstand abnormal conditions and misuse scenarios without fire or explosion risks.
Q: How does this certificate help with Korean and UK market access?
A: The certificate explicitly states evaluation to National Differences for KR (Korea) and GB (Great Britain), meaning the battery pack has been tested against additional requirements specific to these markets. This streamlines the KC certification process in Korea and UKCA marking requirements in the UK, as authorities in these regions will accept the CB certificate as primary evidence of conformity.
