BS is the British standard developed by the BSI Group for technical product documentation, geometric product specification, geometric tolerance specification and engineering drawings.

At best, BS would now simply duplicate the ISO standards, and at worst, it would contradict them in some area; the justification for maintaining an independent Standsrds Standard for mechanical specification had now disappeared.

This document is the standard known as BS Principle changes can be summarized as follows: Find out more about page archiving. The current edition is BS It also brings together, in one easy-to-follow document, all the international standards needed to prepare technical product specifications.

BS references standards covering all aspects of technical product documentation including: This updated version of the standard has been restructured to be more aligned to the workflow of designers and engineers to assist throughout the design process.

A UK school website with electrical symbols openpdf BS Essentially, any engineering drawing should comply with the requirements of BS A review of the design process including drawing examples.


A small break should be added where the extension line meets the drawing. Drawing conventions which applied to BS ‘2’3 in general also apply to the European Standards referenced in BS The withdrawal of BS took place in The first revision to take a major step in this direction was the revision.

A site with lots of useful downloadable documents. The standard now references 3D geometry, not only as drawings but also allowing a 3D surface to be used as a datum feature. The aim is to help the UK industry move over more fully to the ISO system of geometrical product specification.

Drawing conventions Conventions are ways of doing things which conform to a common standard, for example, technical drawings. 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 defines the requirements for the technical specification of products and their component parts. This is the seventh edition of BS Meanwhile, ISO was developing international standards for engineering drawing and tolerancing.

The aim of the standard is no longer simply to index the ISO system, but also to make directly available much of the key material of the ISO standards directly, all in one place.
