BS 8888:2002 Technical Product Documentation (TPD)
Specification for defining, specifying and graphically representing products
This British Standard supersedes BS 8888:2000 which in turn 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BS308-1:1993, BS308-2:1985 and BS308-3:1990, which are all withdrawn.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 general
also apply to the European Standards referenced in BS 8888.
This standard is provided to unify all of the recently implemented ISO and EN ISO standards related to
Technical Product Documentation (it references them). Most designers and engineers should have no difficulty in working to the new
standards. BS 8888 references standards covering all aspects of technical product
documentation including:
- Engineering Flow Diagrams,
- Representation of Engineering components,
- Lettering,
- Units/ quantities,
- Tolerancing,
- Geometric Product Specifications,
- Orthographic/Axometric representation,
- Handling of Computer based information ,
- Metrology etc. etc.
An important difference between BS 308 and BS 8888 is in the marking of
the decimal place. In BS308 the decimal place is indicated with a
decimal point. In BS 8888 the decimal place is indicated with a comma
with 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 a
problem. For Autocad drawings on a Windows based PC it is most convenient set the decimal
point to display as a comma on the regional settings on the control panel (This option is available
if you set the Country to German or France). .
BS 8888 KITS
It is important that anyone working to BS 8888 has convenient access to the referenced European standards.
All of the standards referenced in BS 8888 are grouped into four "Kits". These kits, with linked lists, are provided below
The kits can be procured from British Standards Publishing, see link below, or they are available
for reference in the UK at Central Libraries.
