This is the latest edition of the UK’s technical product documentation and specification standard and the latest version of the standard written to supersede BS 308, the world’s first engineering drawings standard, first published in 1927. Electrical standards and approved codes of practice. Working drawing. This colour scheme had already been introduced for appliance flexes in the UK in the early 1970s, however the original red/black colour scheme recommended by the IEE for fixed wiring was retained until 2006, albeit with change to a green/yellow striped earth in 1976.
