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Figure 33 – Simplification of drawing indication when there is only one This British Standard supersedes BS , which is withdrawn.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.

The federation has grown considerably since those drading days, and now over nations are represented in its membership. Symbolic representation on drawings. BS – What does it mean in practice? Init was split into the three parts that many engineers and designers are familiar with. The standards which govern mechanical engineering specification have become rationalised over recent decades, and there are now two systems of standards which are used almost universally.

BS ensures that its users have access drqwing one reference source with all the relevant information; enables you to speak the same language when specifying and graphically representing products; provides precision and accuracy, leaving no room for misinterpretation; helps the smooth transfer of the design concept to the manufacturing process; shortens the drqwing development time; increases speed to market.

In a number of cases, ISO standards were developed to cover particular topics before any corresponding coverage was developed for BS Find Similar Items This product falls into the following categories. BS was developed, revised and expanded over the years. The standard now references 3D geometry, not only as drawings but also allowing a 3D surface to be used as a datum feature.

Most designers and engineers should have no difficulty in working to the new standards. Not BS Drawing Tools The benefits of BS include improved productivity, reduced costs, and enhanced quality. An important difference between BS and BS is in the marking of the decimal place.

The pages linked below include the majority of these standards. This approach is the driving philosophy behind BS and the current generation of ISO standards, and industry will potentially benefit enormously from its adoption.

Extension lines are parallel lines that extend out from two points on the drawing.

Conventions are ways of doing things which conform to a common standard, for example, technical drawings.

Notes on Drawing using CoralDraw Cadalot The use of dimensions, size tolerances, datums, geometrical tolerances, edge and surface specifications have been formalised and systematised under the heading of Geometrical Product Specification GPS.

Meanwhile, ISO was developing international standards for engineering staneards and tolerancing. The standard is updated frequently to reflect the growing number of international standards which themselves are frequently updated. Acting as a navigational roadmap to the ISO standards, BS provides information engineers need on a regular basis, including the nuts and bolts of engineering rrawing.

As the initials of this organisation could vary when the name was translated into different languages, the initials ISO were adopted as a universal acronym for its name.

The first revision to take a major step in this direction was the revision. The unit of measurement should also be given. Using conventions saves time and ensures that a drawing means the same thing to anyone who sees it.

As such BS acts as a gateway — or roadmap — to around ISO standards on documentation, specification and verification. 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.

BS references standards covering all aspects of technical product documentation including: BS was also widely used overseas, throughout the British Commonwealth.
