Certification follows EU core rules (EU)2024/1180 & supplementary (EU)2025/1871 amendment based on EN17184:2024, EN17240:2024 and UN R144 regulation with three sequential core phases.

Phase1 Pre-Certification Preparation (1~2 months)

Complete EU REP legal entity signing and full technical documentation compilation; most schedule delay originates from inconsistent MSD V3 ASN.1 coding mapping with vehicle CAN bus definition requiring repeated document revision. Full document portfolio includes hardware schematic, BOM, antenna spec, firmware registry, GDPR file, marking drawing and vehicle integration specification finished before lab sample delivery.

Phase2 Formal Laboratory Testing (Official 2~3 months with variable actual cycle)

Split into component IVS testing and full vehicle testing with biggest uncertainty coming from on-board audio tuning and GNSS antenna layout modification:

-Component IVS Protocol Test: Lab simulation of MNO base station & PSAP platform to verify IMS registration, SIP session and MSD V3 transmission; pre-certified off-the-shelf cellular module largely eliminates protocol failure risk with occasional RF & coding revision needed. eCall-only SIM card registration test requires dedicated simulated operator network coverage unavailable via standard RF simulator without unnecessary commercial live network testing cost.

-Full Vehicle Physical Testing Key Risk Items:

·Audio Validation: ITU-T P.1140:2021 acoustic test affected by microphone installation location, vehicle interior resonance and HVAC ambient noise; AEC echo cancellation DSP parameter modification plus repeated real-car testing often consumes over four weeks for one round of tuning.

·GNSS Position Calibration: Metal A-pillar shielding, dashcam signal interference and heated windshield attenuation easily exceed open-sky 3m positioning threshold requiring antenna layout redesign and retest.

·Backup Battery Endurance Test: Mandatory 5+56+5min discharge cycle enforced from 2027 new certification requiring minimum 1.5-month component procurement and testing lead time for 2026 ongoing projects.

Standard test schedule: formal lab testing 2 weeks → failed item rectification 1~3 weeks → retest 1 week; 1 extra month added per full rectification round with multiple revisions extending total cycle heavily.

Phase3 NB Technical Document Audit & Certificate Issuance (1~2 months official lead time)

Test report submission to EU competent authority (KBA Germany, RDW Netherlands, UTAC France, SNCH Luxembourg etc.) for technical file review; authority focuses on document logic consistency, GDPR compliance and product specification matching instead of lab test parameter only. Supplementary document resubmission adds extra 2~4 weeks per revision round. Pre-audit of factory IATF16949 quality document required before certificate issuance to confirm COP audit qualification with remote annual audit eligibility for certified factories.

Real-World Full-Cycle Timeline Summary

1.Ideal scenario (mature pre-certified module, zero rectification, complete one-time document): total certification 4 months maximum from project kickoff to E-mark certificate issuance.

2.Normal project (1~2 minor rectification + single document supplement): full cycle 5~6 months.

3.High-risk revision case (hardware redesign, full audio overhaul, multiple document rejection): certification extends above 8 months missing scheduled vehicle launch window easily.

China Domestic AECS GB45672-2025 Certification Lead Time Reference

Component T-box voluntary CQC certification takes 4~8 weeks without physical crash test; full M1 vehicle type approval requires mandatory crash verification with separate homologation process independent from EU NG eCall without mutual certificate recognition.

Best practice: start NG eCall certification at least 12 months ahead of target vehicle market launch to reserve rectification buffer period.
