This marks the end of an independent British Standard to cover engineering drawing and documentation, and the adoption in full of ISO standards which are used throughout Europe. As such, BS 8888 does not itself document the principles, practices and procedures to be used in engineering documentation, but instead provides references to the relevant ISO standards that now apply.
