Foreword

This BSI Flex was sponsored by The Centre for Connected and Autonomous Vehicles. Its development was facilitated by BSI Standards Limited and it was released under licence from The British Standards Institution. It came into effect on 11th March 2022.

Acknowledgement is given to Nick Reed, Reed Mobility, as the technical author.

The British Standards Institution retains ownership and copyright of this BSI Flex. BSI Standards Limited as the publisher of the BSI Flex reserves the right to withdraw or amend this BSI Flex on receipt of authoritative advice that it is appropriate to do so.

This BSI Flex is not to be regarded as a British Standard or PAS. It will be withdrawn in the event of its being superseded by a PAS or a British Standard.

The agile BSI Flex development process enables a vocabulary to be developed rapidly, and on an iterative basis, in order to fulfil an immediate need in industry. A BSI Flex can be considered for further development as a PAS or British Standard, or constitute part of the UK input into the development of a European or International Standard.

Because the content in this version is part of an iterative process, it is likely to change from time to time with subsequent iterations.

Supersession

This version of BSI Flex 1890 supersedes BSI Flex 1890 v3.0:2020‑10, which is withdrawn.
