The report covers the following major test sections as listed in its table of contents:

Section 1 – General Information: Product description, test standards, summary, methodology, and test facility details
Section 2 – System Test Configuration: EUT justification, exercise software, equipment modifications, test procedures, and decision rule application
Section 3 – Conducted Emission: Measurement uncertainty, emission limits, EUT and instrument setup, and test procedure for conducted emissions

Conducted emission testing verifies that the HB2 does not inject excessive electromagnetic noise back into the AC mains or power lines beyond the permissible limits set by the FCC for Class B devices.

Standards & Compliance

The HB2 PUMP 2 was evaluated against the following regulatory standard:

Standard	Scope	Applicability
FCC CFR 47 Part 15 Subpart B	Unintentional Radiators – Limits and methods for radiated and conducted emissions from digital devices	Primary compliance standard

About FCC CFR 47 Part 15 Subpart B: This subpart of the Federal Communications Commission’s rules governs unintentional electromagnetic emissions from digital electronic devices sold or operated in the United States. It sets limits for both conducted emissions (measured at the power port) and radiated emissions (measured in an open area or semi-anechoic chamber). Class B limits, which apply to devices intended for use in residential environments, are more stringent than Class A limits.

Compliance with FCC Part 15 Subpart B is a prerequisite for the FCC SDoC authorization, which allows the responsible party — in this case Guangdong Bestek Technology Co., Ltd. — to self-declare conformity without the need for a separate FCC grant of equipment authorization for this device class.

The test methodology employed in this report followed the standardized Test Report Form TRF FCC CFR 47 Part 15 Subpart B-EMC-001-V01, which provides a structured procedure for measuring and recording emission data, instrument calibration status, and comparison against regulatory limits.
