Note: The current edition is BS 8888:2011
This British Standard supersedes BS308-1:1993, BS308-2:1985 and BS308-3:1990, which are all withdrawn. Drawing conventions which applied to BS 308-1" 2'3="" in="" generalalso="" apply="" to="" the="" european="" standards="" referenced="" bs="">
This standard is provided to unify all of the recently implemented ISO and EN ISO standards related toTechnical Product Documentation (it references them). Most designers and engineers should have no difficulty in working to the newstandards. BS 8888 references standards covering all aspects of technical productdocumentation including:

An important difference between BS 308 and BS 8888 is in the marking ofthe decimal place. In BS308 the decimal place is indicated with adecimal point. In BS 8888 the decimal place is indicated with a commawith each group of three digits from the decimal provided with a space e.g. 14 234,012 8 .
For manual drawings this is not really aproblem. For Autocad drawings on a Windows based PC it is most convenient set the decimalpoint to display as a comma on the regional settings on the control panel (This option is availableif you set the Country to German or France). .
British Standards are supplying a book which provides clear information on the application of BS 8888this costs �30,0 . The book is titled
BIP 2155:2009 The Essential Guide to Technical Product Specification: Engineering Drawing . {Neil Phelps and Colin Simmons]
This is obtained fromBSI shop.
Note: Chapter 1 can be downloaded free..
This book is also obtained from Amazon ref. The Essential Guide to Technical Product Specification: Engineering Drawing-ordered through this link, I get a small gift if you order from my website
The book linked at the top of the page is an excellent book with a greater range of information. However I do notice that, in my earlier version, drawing examples still use the decimal point -The authors may have corrected thisin the latest version.
In Appendix A of BS 8888 a list of Nominative reference standards is provided. These standards contain the detailed requirements which must by met for claiming complience with BS 8888. The pages linked belowinclude the majority of these standards
