Vietnam_MIC: QCVN 65:2021/BTTTT, QCVN 123:2021/BTTT, and QCVN 124:2021/BTTTT


Vietnam MIC has officially released new National technical regulations regarding SRD, Radar equipment.


1. QCVN 123:2021/BTTT: National technical regulation on Short Range Device (SRD) – Radio equipment to be used in the 40 GHz to 246 GHz frequency range


- QCVN 123:2021/BTTT has been issued together with Circular 10/2021/TT-BTTTT dated October 28, 2021.

- QCVN 123:2021/BTTT shall take effect from July 01, 2022.

- QCVN 123:2021/BTTT has been composed based on EN 305 550-1 V1.2.1 (2014-10) for test method and EN 305 550-2 V1.2.1 (2014-10) for limits


2. QCVN 124:2021/BTTTT: National technical regulation on Radar equipment operating in the frequency range 76 GHz to 77 GHz for ground-based vehicle

- QCVN 124:2021/BTTT has been issued together with Circular 09/2021/TT-BTTTT dated October 20, 2021.

- QCVN 124:2021/BTTT shall take effect from July 01, 2022.

- QCVN 124:2021/BTTT has been composed based on EN 303 396 V1.1.1 (2016-12) for test method and EN 301 091-1 V2.1.1 (2017-01) for limits


Since the QCVN 124:2021/BTTTT only cover Vehicle radar 76 ~ 77 GHz within its scope, if the radar can be operated at a frequency range lager than 76 ~ 77 GHz (eg: 76 ~ 81 GHz), then applicable regulation as below:

1) Vehicle radar 76 ~ 77 GHz need to comply with QCVN 124:2021/BTTTT and EMC QCVN 18:2014/BTTTT.

2) Vehicle radar having operating frequency higher than 40GHz other than 76 ~ 77 GHz need to comply with QCVN 123:2021/BTTTT and EMC QCVN 18:2014/BTTTT.

3) If the vehicle radar operating frequency range is larger than 76 ~ 77GHz (eg: 76 ~ 81 GHz), then it must comply to QCVN 123:2021/BTTTT, QCVN 124:2021/BTTTT, QCVN 18:2014/BTTTT.

4) At the beginning stage, due to limited capability of Vietnamese lab, the MIC may accept equivalent CE standards issued by ISO/IEC 17025 accredited oversea labs to replace QCVN 123:2021/BTTTT and QCVN 124:2021/BTTTT
