Standards & Compliance
The HB3 Air Pump was tested against the following regulatory standards and specifications to achieve FCC SDoC compliance for the US market.
Primary Test Standard
| Standard | Scope | Applicability |
|---|---|---|
| FCC CFR 47 Part 15 Subpart B | Unintentional Radiators – Conducted and Radiated Emissions limits | Mandatory for all unintentional digital/electronic devices sold in the US |
Test Report Form Reference
The testing was conducted using standardized test report form TRF FCC CFR 47 Part 15 Subpart B-EMC-001-V01, which defines the measurement procedures, limit lines, instrumentation setup, and pass/fail criteria applicable to unintentional radiators under FCC jurisdiction.
Compliance Pathway
The product follows the Supplier’s Declaration of Conformity (SDoC) pathway, which requires the responsible party (the applicant/manufacturer) to self-declare compliance based on third-party test evidence. The SDoC pathway is applicable to Class B unintentional radiators under FCC Part 15 Subpart B, and does not require FCC registration or a granted authorization number. The test result of Pass across all applicable emission categories supports a valid SDoC declaration.

Frequently Asked Questions
- What does FCC SDoC mean for the HB3 Air Pump?
-
FCC SDoC stands for Supplier’s Declaration of Conformity. It means that the responsible party — in this case Guangdong Bestek Technology Co., LTD — has tested the HB3 Air Pump through an accredited laboratory and confirmed that it meets the electromagnetic emissions limits defined in FCC CFR 47 Part 15 Subpart B. This declaration allows the product to be legally marketed and sold in the United States without additional FCC registration, as long as the product matches the tested configuration.
- What test report number covers the HB3 Air Pump FCC compliance?
-
The FCC SDoC compliance of the HB3 Air Pump is supported by test report reference number WTH25H09260769E, issued on 2025-10-16 by Waltek Testing Group HCT (Shenzhen) Co., Ltd. The internal lab reference for this report is HCT/RF-23-21.
- Which emissions tests were performed and what were the results?
-
The testing covered both conducted emissions and radiated emissions as required by FCC CFR 47 Part 15 Subpart B for unintentional radiators. The HB3 Air Pump passed all applicable test categories. The test was conducted between 2025-09-30 and 2025-10-09 on a sample received on 2025-09-28.
- Does the FCC SDoC certification expire or become invalid?
-
An FCC SDoC does not have a fixed expiration date, but it becomes invalid if the product undergoes changes that could affect its electromagnetic emissions — such as modifications to the PCB, motor, power supply, or enclosure. If such changes occur, the HB3 would need to be re-tested. The current report (WTH25H09260769E) is valid for the exact product configuration tested in September–October 2025.
