How to Verify an EMC Report (Dont Get Fooled)

The direct answer

Verify an EMC report in six steps: check that the certificate cites the report number, the model matches your product, the dates are recent, the lab is accredited, the standards match your target market, and the N/A lines make sense. Ten minutes of checking kills most borrowed or mismatched documents - because the reports that fool people are not clever, they are just never read.

The six-point checklist

Check	What to verify	Where
1. Certificate matches report	The verification cites a report number; the report exists with that number	Both documents
2. Model matches	Product name and model match your SKU exactly	Cover page
3. Dates are current	Sample and test dates recent; report date before the verification	Header pages
4. Lab is accredited	Recognized accreditations and registrations, verifiable	Test facility section
5. Standards match your market	EN standards for EU; FCC Part 15 for US	Standards list
6. N/A lines make sense	The scope matches the product's power design	Test summary

Check 4 in detail: the lab

The test facility section of an EMC report lists the registrations that make the results meaningful. Our report's lab, Global United Technology Services (Shenzhen), lists:

Registration	What it means
FCC Registration No. 381383	Registered with the US FCC for testing
ISED Registration No. 9079A	Registered with Canadian ISED
NVLAP LAB CODE 600179-0	Accredited under the US NVLAP program

These identifiers are public and checkable. A report with no accreditation or registration section is a summary with a logo, not laboratory evidence.

Check 5 in detail: standards and market

The standards list is where market mismatches hide:

EN IEC 55014-1/2:2021 - EU emissions and immunity for household electrical equipment. This is what a CE/EMC program needs.
FCC Part 15 - the US framework for unintentional radiators. A different assessment, even when the lab is FCC-registered.
CISPR/EN 61000 series - the underlying methods and immunity basics.

If your market is the US and the factory hands you an EN report, it is evidence but not the right evidence. Ask for the FCC Part 15 scope or confirm with the factory what the report actually covers.

Check 6 in detail: the N/A lines

The N/A column tells you whether the scope matches the product:

A battery-powered product should show the mains tests as N/A - that is correct (Article E5).
An AC-powered product showing the same tests as N/A is a red flag.
The applicable tests - radiated emission, ESD, radiated immunity - should be present and passed on any electronic product.

The red flags

A certificate with no report number. A verification should cite its report.
A report with no test facility section. Real reports always name and accredit the lab.
Model mismatch. A report for "a series" without your model covers nothing.
Impossible dates. Verification dated before the report, or a report older than your product.
Wrong market standards. An EN report presented as US compliance, or vice versa.
All-N/A summaries. If every test line is N/A, the report is documenting nothing.
No criterion column in immunity results. Without A/B/C, "pass" has no meaning (Article E6).

Factory data: We publish this checklist because our own documents have to survive it. Every request for our EMC evidence gets the same response: the report, the verification, the lab registrations and a straight answer about what the documents do and do not cover. A buyer who cannot verify a document should not trust it - and we would rather lose the sale than the trust.

What a complete set looks like

Using our Model 1338 as the example:

Element	What it shows
Report No. GTS2025080251E01	Tests, standards, results, criterion column, lab section
Verification No. GTS2025080251EV1	Cites the report, names the standards, states the CE responsibility chain
Test summary	Pass on applicable items, N/A with a clear cause on the mains family
Test facility section	FCC 381383, ISED 9079A, NVLAP 600179-0

Every element cross-references another. That is what a genuine document chain looks like - and it is exactly what borrowed or fabricated documents cannot produce.

FAQ

How do I check a lab's accreditation?

Look up its registration numbers (FCC, ISED, NVLAP and similar) on the respective public databases. The numbers in the report should resolve to the lab and be current.

Is an EN report valid for the US market?

It is evidence of EU-scope testing, not US compliance. US market access for the electronics typically needs an FCC Part 15 assessment. Check the standards list before assuming coverage.

What if the factory sends only the certificate?

Ask for the report. A verification without its report is an unverifiable claim; the report is where the model, dates, limits and criteria live.

How recent should an EMC report be?

Current enough that the product configuration and standards versions have not changed. EMC reports do not expire like certificates, but material changes to the electronics or power supply invalidate the coverage.

What does an all-N/A report mean?

It means no tests were applicable - which is suspicious for any product with electronics. Radiated emission, ESD and immunity apply to electronic products regardless of power source.
