BS is the British standard developed by the BSI Group for technical product documentation, geometric product specification, geometric tolerance specification and engineering drawings. Figure 33 – Simplification of drawing indication when there is only one This British Standard supersedes BS , which is withdrawn. Technical Drawing standards create a 2D Graphical Language. I’ve based the information on these posts on BS , the British standard for ‘Technical.

Designers and engineers now had to make use of the extensive catalogue of ISO standards frawing cover different aspects of Technical Product Specification. The pages linked below include the majority of these standards.

UK’s national standard for engineering drawings revised | BSI Group

The benefits of standardisation became widely recognised during the industrial revolution. This approach is the driving philosophy behind BS and the current generation of ISO standards, and industry will potentially benefit enormously from its adoption.

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. One-off, batch, and mass or continuous production all have different design requirements, because of the differences between types of product, client [ client: Tolerancing and dimensioning kit Computer aided engineering kit Design Management Added Standards in Industrial design One-off, batch, and mass or continuous production all have different design requirements, because of the differences between types of product, client [ client: The federation has grown considerably since those early days, and now over nations are represented in its membership.

Please consider upgrading your browser software or enabling style sheets CSS if you are able to do so. A significant change in the 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.

Find out more about page archiving. Extension lines are parallel lines that extend out from two points on the drawing. Essentially, any engineering drawing should comply with the requirements of BS As such BS acts as a gateway — or roadmap — to around ISO standards on documentation, specification and verification.

It also brings together, in one easy-to-follow document, all the international standards needed to prepare technical product specifications.

Size tolerances should be interpreted in accordance with ISO i. Links Providing information on Drawing Draughstman. To address this need, a number of the major national dtawing bodies formed a federation known as the International Organization for Standardization. Meanwhile, ISO was developing international standards for engineering drawing and tolerancing.

For industry, this can mean fewer disputes over compliance or noncompliance of components, reduced scrap and re-works rates, and fewer queries due to incomplete specifications.

crawing Lots of Advice and Lessons from a Drawing expert Metrication. Most designers and engineers should have no difficulty in working to the new standards.

Notes on Drawing using CoralDraw Cadalot Independent design consultancies or design agencies are also set to benefit from BS A review of the design process including drawing examples.

The benefits of BS include improved productivity, reduced costs, and enhanced quality. Standard Number BS Not BS Drawing Tools An important difference between BS and BS is in the marking of the decimal place. This page has been archived and is no longer updated.

It was in effect just an expensive shopping list. The standard has been restructured to make it easier to find key information and to improve the flow of requirements, reflecting how they will be used by designers and engineers in practice More information has been included on model based definition, i.

In BS the decimal place is indicated with a decimal point. The first revision to take a major step in this direction was the revision. 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.

The illustration below shows two drawings conforming to BS specifications.

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 British Standard for mechanical specification had now disappeared.

For manual drawings this is not really a problem. Finally, from market research conducted by BSI in recent years, we know that many organizations are still using the withdrawn BS as they find the new ISO standards covered by BS too complex to move over to.

A small break should be added where the extension line meets the drawing. The standards cover more than just engineering drawing, they cover all aspects of technical product specification, including, for instance, the use of 3D CAD models to define component geometry.
