(ISO: Geneva) -- The International Organization for Standardization (ISO) and Danish Standards (DS, the ISO member for Denmark) have jointly published a handbook on geometrical product specifications (GPS) 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 written by Henrik S. Nielsen, Ph.D., 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.
