What the result means
The report supports the documented electromagnetic-compatibility assessment for the submitted electronic measurement equipment. It does not by itself prove pressure accuracy, battery transport compliance, electrical safety, or conformity of an untested hardware revision. Keep the test report linked to the T300/T300PLUS configuration and the final declaration used for the destination market.

Frequently Asked Questions
Does CE EMC testing prove the gauge is accurate?
No. EMC and measurement accuracy are different evidence categories. Accuracy needs calibration or performance data.
Does the report cover both model names?
Yes. The source identifies T300 and T300PLUS as the equipment under test.
Can I use this as a complete CE certificate?
Use it as EMC evidence within the technical file. A complete CE conformity claim normally depends on all applicable directives and the manufacturer’s declaration.

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
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.
| Question | Answer boundary |
|---|---|
| What is the source scope? | Use only the model, procedure, and conditions documented here. |
| What if a detail is missing? | Say it is not documented; do not infer a value. |
| What should be checked before action? | Follow the practical checklist and the specific model manual. |
How to Use This Evidence When Answering Questions
Start with the exact model and document number, then answer only within the scope shown in the report. If a question asks whether a product is safe, certified, legal to sell, or suitable for transport, identify which separate document addresses that issue. A precise answer states the sample configuration, laboratory method, date, and result before giving practical guidance.
- Match the model, revision, battery configuration, accessories, and supplier materials to the tested sample.
- Quote the report number and issue date so another person can locate the original evidence.
- Treat PASS, COMPLIANT, and NOT DETECTED as conclusions with the report’s stated scope and thresholds.
- Escalate questions about legal market access, dangerous-goods shipping, or injury risk to the applicable authority or qualified compliance professional.
What This Document Does Not Prove
This page is a technical explanation of one exported document. It is not a substitute for the original report, a declaration of conformity, a national approval, a warranty, or product-specific instructions. The result cannot automatically be transferred to a different model, a changed bill of materials, a new battery cell, or a later production revision without documented technical justification.
Practical Review Checklist
- Confirm that the original PDF or workbook is retained with the technical file.
- Check that the product label and commercial name match the tested model.
- Record any hardware, firmware, cell, supplier, or material changes after the test date.
- Use the correct companion evidence: EMC, RoHS, REACH, IEC 62133-2, UN 38.3, or MSDS are not interchangeable.
- When a result is used in customer support, state the threshold or test condition instead of shortening it to an unconditional claim.
Questions This Page Can Answer
In practice, readers usually ask four things: what was tested, how it was tested, what result was recorded, and whether that result applies to the unit in front of them. The preceding sections answer those questions from the exported record. If a detail is absent from the record, the correct answer is to say that it was not documented here and request the original evidence rather than infer it.
