Standards & Compliance
The Air3 was evaluated against the following regulatory standards and test methods to confirm compliance with US electromagnetic compatibility (EMC) requirements.
- 47 CFR Part 15, Subpart B (October 2020 edition) — The core FCC rule governing unintentional radiators. It sets limits on spurious radio frequency emissions from digital devices to prevent interference with licensed radio communications.
- ANSI C63.4:2014 + A1:2017 — The American National Standard for methods of measurement of radio-noise emissions from low-voltage electrical and electronic equipment in the range of 9 kHz to 40 GHz. This standard defines the specific test procedures used during the EMC evaluation.
- FCC Section 2.906 — Governs the SDoC procedure, requiring the responsible party (Guangdong Bestek Technology Co., LTD) to retain test records and supply them to the FCC upon request before marketing the device in the United States.
- FCC Section 15.19(a) — Mandates that the device bear the required FCC compliance label. Voluntary use of the FCC logo is permitted only for products that fully satisfy all SDoC procedures.
Validity & Certification Body
The Verification of Conformity bearing Reference No. WTH25H07182969E was issued on July 25, 2025 and is valid as long as the product configuration, components, and manufacturing processes remain unchanged from the tested sample. Any material change may require re-evaluation.

Frequently Asked Questions
- What does FCC SDoC mean for the ETENWOLF Air3?
- FCC SDoC (Supplier’s Declaration of Conformity) means that Guangdong Bestek Technology Co., LTD has self-declared, supported by third-party test results from Waltek Testing Group HCT, that the Air3 complies with the radio frequency emission limits in 47 CFR Part 15, Subpart B. This authorises the product to be legally marketed and sold in the United States.
- Which test standard was used to evaluate the Air3?
- The Air3 was tested using ANSI C63.4:2014 + A1:2017, the American national standard for measuring radio-noise emissions from low-voltage electronic equipment, in accordance with 47 CFR Part 15, Subpart B (October 2020).
- Is the FCC logo printed on the Air3?
- The FCC rules allow voluntary use of the FCC logo on SDoC-authorised products. The Air3 must carry the mandatory FCC compliance statement per Section 15.19(a). Use of the FCC logo itself is optional but is only permitted when the product fully meets all SDoC procedures.
- Does this certificate cover all units produced?
- No. As stated in the VoC document (Ref. WTH25H07182969E), the certification is based on a single sample test and does not imply an assessment of the entire production run. The responsible party is required to maintain production consistency with the tested sample to sustain compliance.
