Key Details
The following standards were applied during EMC testing of the T300 / T300PLUS. All tests were conducted by Waltek Testing Group HCT (Shenzhen) Co., Ltd. on a representative product sample, and the results confirmed full compliance with the listed requirements.
| Standard | Scope | Result |
|---|---|---|
| EN IEC 61326-1:2021 | Electrical equipment for measurement, control and laboratory use — EMC requirements — Part 1: General requirements | Pass |
| EN IEC 61000-3-2:2019+A1:2021 | Limits for harmonic current emissions (equipment input current ≤16 A per phase) | Pass |
| EN 61000-3-3:2013+A2:2021 | Limitation of voltage changes, voltage fluctuations and flicker in public low-voltage supply systems for equipment with rated current ≤16 A per phase and not subject to conditional connection | Pass |
The test reports referenced under this certificate demonstrate that the product meets the essential EMC requirements under Directive 2014/30/EU. Compliance with other relevant EU Directives remains the responsibility of the applicant.
Standards & Compliance
The T300 / T300PLUS was evaluated against three harmonised European standards that together constitute the EMC compliance framework for measurement and control equipment sold within the European Economic Area (EEA).
- EN IEC 61326-1:2021 — Establishes general EMC requirements (immunity and emissions) for electrical equipment used in measurement, control, and laboratory environments. This is the primary product-family standard applicable to electronic gauges.
- EN IEC 61000-3-2:2019+A1:2021 — Sets limits on harmonic current emissions injected into the public supply network by equipment drawing ≤16 A per phase, preventing interference with other connected devices.
- EN 61000-3-3:2013+A2:2021 — Controls voltage fluctuations and flicker caused by equipment operating on public low-voltage supply systems, ensuring grid stability and protection of other users.
Compliance with these harmonised standards provides a presumption of conformity with the essential requirements of EU EMC Directive 2014/30/EU, authorising the CE mark to be affixed to the product and its packaging.
Validity & Certification Body
This certificate was issued on July 21, 2025 and is signed by Tony Wu, General Manager of Waltek Testing Group HCT (Shenzhen) Co., Ltd. The evaluation is based on a single sample assessment and does not constitute an audit of the entire production line.

Frequently Asked Questions
- What does the CE-EMC certification mean for the T300 / T300PLUS tire pressure gauge?
-
CE-EMC certification means the T300 / T300PLUS has been independently tested and confirmed to comply with the EU EMC Directive 2014/30/EU. It demonstrates that the device neither generates harmful electromagnetic interference nor is susceptible to interference that would affect its performance. The CE mark signals legal market access across the European Economic Area.
- Which specific standards were used to test the T300 / T300PLUS?
-
Three harmonised standards were applied: EN IEC 61326-1:2021 (general EMC requirements for measurement 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 passing result.
- Who conducted the EMC testing and issued the certificate?
-
Testing and certification were carried out by Waltek Testing Group HCT (Shenzhen) Co., Ltd., a professional third-party testing and certification body based in Shenzhen, China. The certificate (Reference No. WTH25H07183005E) was signed by Tony Wu, General Manager, on July 21, 2025.
- Does this certificate cover all units produced, or only the tested sample?
-
As stated in the certificate, the evaluation is based on a single product sample. It does not imply an assessment of the entire production batch. The applicant — Guangdong Bestek Technology Co., Ltd. — is responsible for maintaining production consistency and preparing the full technical documentation and EU Declaration of Conformity.
