Resources 02 · The test laboratories

We don’t own labs. We know exactly which one your question needs.

Photometry, EMC, safety, IP, thermal, reliability — each test lives in a different accredited laboratory around us. Our job is to specify the right test, place it at the right lab, witness what matters, and pass the fee through at cost. No markup. Ever.

01 / The network

What we can place, and where it runs.

These are the test families we arrange routinely. Accreditation status is verified before any booking — an unaccredited report is worse than none.

PHOTOMETRY
Integrating sphere · goniophotometer
Flux, efficacy, CCT/CRI/R9, spatial distribution, IES/LDT files. The goniophotometer rooms we use are among the few qualified to issue files a European lighting designer will actually trust.
EMC
EMI emission + immunity chambers
EN 55015 conducted and radiated, EN 61000-3-2/-3-3 harmonics and flicker, EN 61547 immunity suite. Full anechoic chambers within the region — pre-compliance debugging and formal runs in the same building.
SAFETY
Electrical safety to IEC 60598
Dielectric, creepage/clearance, thermal rise at rated conditions, fault conditions — the backbone of a credible CE technical file.
INGRESS
IP / IK verification
Dust chambers and jet-nozzle rigs. Where a factory "self-declares IP65" without a test, this is the room that ends the argument.
THERMAL & LIFE
Thermal imaging · ageing racks
Tc-point verification with thermocouples, long-duration life-test racks for driver and engine samples — the evidence layer behind the lifetime chain lock.
COMPONENT
LM-80 / reliability partners
For LED packages and drivers we work with labs maintaining LM-80-class equipment, plus destructive analysis (X-ray, cross-section) for failure cases.
02 / How we place a test

Four steps, and who does what.

You never deal with the lab directly — but you see every document it issues.

STEP 1

Specify

We translate your engineering question into a test plan: which standard, which samples, which conditions, which pass/fail limits.

OUT · test plan
STEP 2

Pre-approve

Cost, duration and sample logistics are quoted to you before anything ships. You approve the spend; there is no surprise line later.

OUT · LTO order form
STEP 3

Witness

Samples are delivered under our chain of custody. For judgement-critical runs, we witness the test in person — the lab is a drive away.

OUT · witness record
STEP 4

Report & interpret

The accredited report comes to you untouched. On top of it, you get our interpretation: what the numbers mean for your purchase decision.

OUT · accredited report + note
03 / At cost — the fee rule

Why a buying agent with no lab markup matters.

This page has a second argument, and it is structural.

STRUCTURE

The lab works for us, not for the factory

A factory-nominated lab has a customer relationship with the factory. The lab we nominate has none — it gets paid by the test, and its accreditation is on the line for every report.

STRUCTURE

At cost keeps the incentive clean

If tests carried a margin, every failure analysis would magically recommend more testing. Ours don't: the lab fee on your invoice is the lab fee on ours, and the LTO form shows it.

STRUCTURE

Accreditation is checked, not assumed

CNAS / ISO 17025 scope is verified against the accreditation body's database before booking — the same discipline we apply to factory certificates at the audit gate.

04 / What we don't do

The lab boundary, stated plainly.

Because this is where ambiguity would cost you later.

✕We don't issue certificates — accreditation bodies do. We specify tests, place them and interpret them.
✕We don't mark up lab fees — the LTO form shows the lab's own cost, passed through unchanged.
✕We don't accept factory-chosen labs — for judgement-critical tests. The nomination right is part of the evidence chain.
✕We don't skip pre-approval — no test is booked before you have seen the cost and approved it in writing.

Have a test question or a dispute that needs evidence?

Describe the product and the doubt. We'll come back with the test family, the standard, the accredited lab and the at-cost fee — usually within 24 hours.
