Drawings
When a factory is built in Chile by a French
construction company following Swedish plans… that's when you understand the importance of technical
drawing standards. It would be difficult to find a sector of industrial activity that does not require
the use of drawings. Goods of a technical nature nearly always need to be accompanied by service information
for technical drawings illustrating the items, their assembly and their use. This applies not only to
complex assemblies such as motor cars or textile machines, but also to items of personal or household
equipment, such as razors, hair-dryers, kitchen appliances or vacuum cleaners.
It is essential that a drawing prepared in one country can be correctly interpreted in another, even when the users do not speak the same language. Hence the need for International Standards for technical drawings and graphical symbols.
The technical committee ISO/TC 10, Technical product documentation, offers some 150 standards for technical drawings.
