2026-04-22

Timeline varies drastically by product and certification route.

Step 1: Confirm Certification Route

Choose between KATS (Safety/EMC) and RRA (radio).Missing one route causes severe delays.

Step 2: Prepare Samples & Documents

·Samples: full functional units

·Documents: manual, circuit diagram, BOM, model difference statement

Preparation: 1–2 weeks (longer with repeated revisions)

Step 3: Laboratory Testing

·KC Safety: 2–4 weeks

·KC EMC: similar

·KC (RRA): 3–5 weeks (standard products)

Step 4: Review & Certification

·Mandatory Safety: review + factory inspection

·EMC / RRA: direct certification after review

Step 5: Certificate Validity & Maintenance

·Mandatory KC: 5-year validity with annual follow-up audit

·Voluntary / SDoC: 5-year validity, no annual inspection

Realistic Timeline

·Low-risk voluntary: 3–6 weeks

·Standard mandatory: 2–4 months

·Full radio + safety + EMC: 2–4 months+

Delays occur from testing failures and incomplete documents.
