Compliance is a design input, not a paperwork phase
€8–25k of EMC retests trace back to four decisions you make at architecture.
Component choice, antenna placement, ground plane partitioning, and enclosure aperture math determine whether your first EMC lab visit ends in a Declaration of Conformity or a 6-week PCB redesign. We work the compliance route into the architecture, not into the final week before shipping.
CE marking — directive triage
Which directives actually apply to your product (RED, EMC, LVD, MD, RoHS, EU Battery, EU CRA, GPSR)? Each adds a different harmonised standard, test scope, and label requirement. The wrong directive list = wrong lab quote, wrong technical file.
FCC, IC, UKCA routes
FCC Part 15 vs Part 18 vs Part 22/24/27. Modular vs intentional vs unintentional radiator. UKCA divergence from CE post-Brexit. The right path saves €3–15k vs the wrong one and 2–6 weeks of timeline.
EMC pre-compliance scan
3-metre semi-anechoic chamber scan costs €1.5–3k vs €8–15k for a full formal lab retest. We define the test list, the failure margin to aim for, and the PCB or shielding changes if the scan misses.
Battery & transport compliance
UN 38.3 for transport (€4–6k per cell variant), IEC 62133 for cell safety, EU Battery Regulation 2023/1542 for passport + due-diligence, plus PI966/PI967/PI970 air-shipping classes by Wh/cell.
Technical file & DoC
Full technical file: schematics, BOM, test reports, risk assessment (EN 62366 for usability if medical, ISO 12100 if machinery), instructions, labels, traceability. Stored 10 years after last unit. The CE auditor checks the file, not the product.
Production conformity
Every shipped unit must match the certified sample. Serial number traceability, AQL inspection on critical features, supplier change control (PCN), and field-failure reporting per GPSR Article 9. The certification is the start, not the end.
