Standards & Compliance
The T200 Tire Pressure Detector was evaluated against the following regulatory standard:
| Standard | Scope | Authority |
|---|---|---|
| FCC CFR 47 Part 15 Subpart B | Unintentional Radiators — Conducted and Radiated Emission Limits | Federal Communications Commission (FCC), USA |
FCC CFR 47 Part 15 Subpart B establishes the technical standards for unintentional radiators — devices that generate radio frequency energy incidentally as a byproduct of their operation. Compliance demonstrates that the T200 does not cause harmful interference to other electronic devices or communication services operating within the United States.
The test methodology followed the Test Report Form TRF FCC CFR 47 Part 15 Subpart B-EMC-001-V01 and included:
- Conducted emission measurements using a calibrated spectrum analyzer and LISN (Line Impedance Stabilization Network)
- Radiated emission measurements performed in a suitable RF test facility with corrected amplitude and margin calculations
- Application of the laboratory’s documented decision rule for pass/fail determination
- Full recording of test equipment used, including calibration traceability (Sections 3.6 and 4.7 of the report)
Validity & Certification Body
The test report was issued on 2025-07-21 by Waltek Testing Group HCT (Shenzhen) Co., Ltd., an accredited EMC and RF testing laboratory operating under the internal quality reference HCT/RF-23-21.

FCC SDoC test reports do not carry a fixed expiration date in the same manner as third-party certifications; however, the declaration remains valid as long as the product continues to be manufactured to the same specifications tested. Any design change that could affect RF emissions would require re-evaluation against FCC CFR 47 Part 15 Subpart B.
Frequently Asked Questions
- What does the FCC SDoC for the T200 Tire Pressure Detector confirm?
-
The FCC Supplier’s Declaration of Conformity (SDoC), supported by test report WTH25H07183012E, confirms that the T200 Tire Pressure Detector complies with the conducted and radiated emission limits set out in FCC CFR 47 Part 15 Subpart B. This means the device can be legally sold and used in the United States without causing harmful electromagnetic interference to other equipment.
- Which test laboratory performed the FCC emission testing for the T200?
-
Testing was conducted by Waltek Testing Group HCT (Shenzhen) Co., Ltd., located in Longgang District, Shenzhen, Guangdong, China. The tests were carried out between 2025-07-14 and 2025-07-17, and the report was issued on 2025-07-21. The report was prepared by Snow Zeng and approved by Tony Wu.
- What is the difference between FCC SDoC and FCC ID certification?
-
FCC SDoC (Supplier’s Declaration of Conformity) is a self-declaration path available for certain unintentional radiators under Part 15 Subpart B. The manufacturer or importer tests the product and declares compliance without requiring FCC authorization. FCC ID certification, by contrast, involves third-party review and results in a registered FCC ID number on the device. The T200 qualifies under the SDoC route as a Part 15 Subpart B unintentional radiator.
- Does this FCC test report cover the T200 for markets outside the United States?
-
No. Report WTH25H07183012E specifically addresses FCC CFR 47 Part 15 Subpart B requirements for the US market. For other markets, separate certifications may be required — for example, CE marking for the European Union, KC certification for South Korea, or other regional EMC approvals.
