NBTC Certification for Vehicle Radar Systems

Vehicle radar systems — used in automotive applications such as adaptive cruise control, collision avoidance, and blind-spot detection — require NBTC certification before they can be imported or sold in Thailand. The certification path depends on the frequency band and, for the 24 GHz band, on transmit power.

Scope

This page covers vehicle radar only. For general-purpose radar equipment used in industrial, weather, or level-measurement applications, see the Radar page.

Certification Requirements

All bands are governed by NBTC TS 1011-2560.

24 GHz split path: Devices transmitting at or below 10 mW eirp qualify for SDoC. Devices exceeding 10 mW eirp require Class A Registration. All other vehicle radar bands are Class A only. The 22.00–26.65 GHz band uses a spectral density power limit expressed as −41.3 dBm/MHz eirp.

Required Documents

For SDoC submissions:

  • Technical specification or datasheet including wireless communication details
  • Product photos
  • Test reports (RF, Safety, EMF/SAR as applicable) from accredited laboratories
  • Authorised declaration

For Class A submissions (additional requirement):

  • ISO/IEC 17025 accreditation certificate and laboratory scope

No physical product sample submission is required.

Indicative Timeline

SDoCApproximately 1 week from submission
Class AApproximately 5 weeks from submission

Additional time may be required if NBTC requests supplementary documents during review.
