Certification Scope: The verification confirms compliance with FCC Rules and Regulations Part 15, Subpart B, which governs unintentional radiators – devices that generate radio frequency energy during operation but are not designed to intentionally emit radio waves.
Standards & Compliance
The S1 tire inflator underwent testing according to the following regulatory frameworks and technical standards:
47 CFR Part 15 – Radio Frequency Devices:
This FCC regulation establishes technical standards and operational requirements for radio frequency devices. Part 15 Subpart B specifically addresses unintentional radiators – equipment that contains digital circuitry or switching power supplies that may generate electromagnetic interference.
ANSI C63.4:2014 +A1:2017:
This American National Standards Institute specification provides standardized methods for measuring radio-noise emissions from low-voltage electrical and electronic equipment. The measurement procedure ensures consistent, repeatable test results across different testing facilities.
Compliance Verification Method:
- Testing conducted according to Supplier’s Declaration of Conformity (SDoC) procedures per Section 2.906 of FCC rules
- Device labeled according to Section 15.19(a) requirements
- Test reports and compliance documentation maintained by responsible party for FCC review
- Electromagnetic emissions tested to ensure they remain below FCC limits for unintentional radiators
The verification confirms the device does not cause harmful interference to radio communications and accepts any interference received, including interference that may cause undesired operation, as required by FCC Part 15.19(b).

Important Notice: This Verification of Conformity is based on testing of a single sample unit. It does not constitute an assessment of the entire production run. The responsible party must maintain test reports and provide them to the Federal Communications Commission upon request. Marketing the device in the USA requires filing a Supplier’s Declaration of Conformity according to Section 2.906 of FCC rules prior to sale.
Frequently Asked Questions
What does FCC-SDOC certification mean for the S1 tire inflator?
FCC-SDOC (Supplier’s Declaration of Conformity) certification confirms that the ETENWOLF S1 tire pump has been tested and complies with FCC Part 15 regulations for electromagnetic compatibility. This means the device has been verified not to cause harmful interference to radio communications and is legally authorized for sale and use in the United States market.
Is the S1 tire inflator safe from electromagnetic interference?
Yes, the S1 has been tested according to ANSI C63.4:2014 measurement standards and found compliant with 47 CFR Part 15 Subpart B requirements. This certification confirms the device’s electromagnetic emissions remain within acceptable limits and will not interfere with other electronic equipment or wireless communications under normal operating conditions.
Who is responsible for maintaining FCC compliance documentation?
The responsible party (Guangdong Bestek Technology Co., LTD) must maintain complete test reports and compliance documentation. These records must be provided to the Federal Communications Commission upon request. Before marketing the S1 in the USA, the responsible party must file a Supplier’s Declaration of Conformity according to FCC Section 2.906 requirements.
Can the FCC logo be displayed on the S1 tire pump?
Yes, devices authorized under Supplier’s Declaration of Conformity may voluntarily display the FCC logo. However, use of the FCC logo is limited to products that fully comply with SDoC procedures and maintain all required documentation. The device must also meet Section 15.19(a) labeling requirements regardless of whether the FCC logo is used.
