BS 308 was formally the standard for engineering drawing since 1927. Over a period of 73 years it was expanded and edited until its withdrawal in 2000. The BSI Group, who produced the standard, played an important role in the development of the international standard on technical specification in conjunction with the ISO. In 2000, the BS 308 was retired and replaced by the updated BS 8888.
A significant change in the 2008 revision is that there is no longer a requirement to state whether specifications have been toleranced in accordance with either the Principle of Independency or the Principle of Dependency.
BS 8888 performs three fundamental tasks:
- Unifying all the ISO standards applicable to technical specification;
- Giving an index of ISO standards involved with different principles of technical product specification (TPS);
- Providing BSI with a platform for further explanatory commentary where necessary.
