The FINANCIAL -- ISO and
Danish Standards have jointly
published a handbook on geometrical product specifications for
which nearly 120 ISO standards provide a globally harmonized base for
technical drawing, with benefits for manufacturing and trade.
The ISO Geometrical Product Specifications Handbook – Find your way in GPS, is authored by Dr. Henrik S. Nielsen, Chair of ISO technical committee ISO/TC 213, which develops GPS standards with the participation of ISO national member bodies in 23 countries.
GPS standards provide an international language of symbols for expressing tolerances in technical drawing. This makes it possible for a drawing of a component that has been developed in one country to be sent to another country on the other side of the world, where the drawing can be understood and the component manufactured, without the designer and supplier having any common language except GPS.
Through easy-to-understand colour illustrations and specific examples, the handbook guides the reader through the basic rules for interpreting the graphic GPS language and provides a step-by-step procedure for tolerancing components and products using GPS.
The book also shows how everyone involved in product realization, from idea conception to manufacturing and verification, can benefit from the use of GPS. This is because GPS tolerances can express functional requirements more precisely and therefore be made larger, so that components become less expensive to produce.
