Key Details
The test report covers three major EMC test areas as required under the applicable CE directives. The following table summarises the scope of each test section as documented in the report’s table of contents and header information.
| Test Section | Standard Applied | Test Focus | Result |
|---|---|---|---|
| Disturbance Voltage at Mains Terminals (Conducted Emissions) | EN IEC 61326-1:2021 | Measurement of conducted radio-frequency disturbance voltage on power supply lines | Pass |
| Harmonic Current Emissions | EN IEC 61000-3-2:2019+A1:2021 | Limits for harmonic current emissions for equipment with input current up to and including 16 A per phase | Pass |
| Voltage Fluctuations and Flicker | EN 61000-3-3:2013+A2:2021 | Limitation of voltage changes, voltage fluctuations and flicker in public low-voltage supply systems | Pass |
The report spans 44 pages in total, including detailed measurement data, instrument calibration records, test configuration diagrams, and decision rule applications. All measurements were conducted within the laboratory’s accredited scope under controlled conditions.
Standards & Compliance
The T300/T300PLUS was evaluated against the following harmonised European standards, which support the CE marking declaration for the EMC Directive 2014/30/EU:
| Standard | Title | Relevance |
|---|---|---|
| EN IEC 61326-1:2021 | Electrical equipment for measurement, control and laboratory use — EMC requirements — Part 1: General requirements | Primary EMC standard for the product category; covers both emissions and immunity |
| EN IEC 61000-3-2:2019+A1:2021 | Electromagnetic compatibility — Limits for harmonic current emissions | Controls harmonic distortion injected into the mains supply |
| EN 61000-3-3:2013+A2:2021 | Electromagnetic compatibility — Limitation of voltage changes, voltage fluctuations and flicker | Ensures the product does not cause perceptible flicker on the public supply network |
Compliance with these standards demonstrates that the T300/T300PLUS meets the essential requirements of the EU EMC Directive and is eligible to bear the CE mark for sale throughout the European Economic Area. The test report form used (TRF EN IEC 61326-1:2021-EMC-001-V01) is the standardised template for this product class.

Frequently Asked Questions
- What does CE-EMC certification mean for the T300/T300PLUS tire pressure gauge?
-
CE-EMC certification means the T300/T300PLUS has been independently tested and found to comply with EU Directive 2014/30/EU on electromagnetic compatibility. This confirms that the device neither emits electromagnetic disturbances above permitted limits nor is susceptible to interference in ways that would impair its operation. The CE mark allows the product to be legally placed on the market across all European Economic Area member states.
- Which specific standards were tested in report WTH25H07183005E?
-
Report WTH25H07183005E covers three standards: EN IEC 61326-1:2021 (general EMC requirements for measurement and control equipment), EN IEC 61000-3-2:2019+A1:2021 (harmonic current emission limits), and EN 61000-3-3:2013+A2:2021 (voltage fluctuation and flicker limits). All three tests returned a Pass result.
- Who conducted the EMC tests for the T300/T300PLUS?
-
The tests were conducted by Waltek Testing Group HCT (Shenzhen) Co., Ltd., an accredited third-party testing laboratory based in Shenzhen, Guangdong, China. The report was prepared by Snow Zeng and approved by Tony Wu. Testing took place between 2025-07-15 and 2025-07-17, with the report issued on 2025-07-17.
- Does this EMC report cover both T300 and T300PLUS models?
-
Yes. Report WTH25H07183005E explicitly lists both the T300 and T300PLUS as the model numbers under test. Both variants of the electronic tire pressure gauge are covered by the same test findings and Pass result recorded in this document.
