Test Failure Triage
Failed a test? Get a fix plan before you rebook the lab
A failed test report tells you that a limit was exceeded. It rarely tells you why. Teams often go back to the lab with a guess, pay for another slot, and fail again — while the launch date moves each time.
Most failures have a short list of usual suspects: cable and enclosure emissions, clock harmonics, power supply noise, antenna placement, a test configuration that doesn't represent the product. Narrowing that list from the report and the design is engineering work, and it is far cheaper than a second failed visit.
Triage gives you a ranked list of causes, the fixes to try first and a retest plan in three business days. If you want us to see it through, the fee comes off the engagement.
What you receive
- A plain-language read of the failing results: which limits, which frequencies, which test setup
- The most likely causes, ranked, with the design or setup evidence that points to each
- Specific fixes to try first, and what to measure to confirm them before going back to the lab
- A retest plan: what to retest, what can stand, and what to ask the lab for
Who this is for
- Your product failed emissions, immunity, radio or safety testing
- You have a lab report but no clear idea what to change
- You're deciding whether to redesign or to argue the test setup
- You need a credible plan to show your team or investors before rebooking the lab
How it runs
- 1
Send the report
The lab report, plus whatever helps: schematics, layout, photos of the test setup, the product's cabling and power arrangement.
- 2
We read the results
Failing limits, frequencies and conditions are mapped against the standard and the likely sources in your design.
- 3
Causes and fixes
A ranked list of probable causes, with the fixes to try first and how to verify each before the lab.
- 4
Retest plan
What to retest, what can stand, and a fixed quote if you'd like us to take it from here.
Worth knowing
Checkable facts, with the source. Useful whether or not you buy anything from us.
Pre-compliance review work is widely reported to cut first-pass lab failure rates from roughly 50% to under 10%.

Re-test fees after a failed formal submission are commonly reported in the $10,000–$30,000 range once redesign and lab time are included.

Common questions
Is the fee credited?
Yes. If you start a Compliance Rescue, Market Launch or Multi-Market Launch within 60 days of the triage, the full $300 comes off it.
Can you guarantee the fix will pass?
No one honestly can from a report alone. What you get is the most likely causes, ranked, and a way to check each one cheaply before you spend money on another lab slot.
What if the problem is bigger than a fix?
Then the triage says so, and Compliance Rescue is the follow-on: hands-on recovery through to a passing report.
Do you test the product yourselves?
No. Krono is not a test lab. We read the evidence, advise on fixes and coordinate with your lab; accredited testing stays with the lab.
