Paper Abstract

New generation Geometrical Product Specifications (GPS) consist of a series of standard drafted by ISO/TC 213, which relate to drawing indication, definition of tolerance and values of specifications, characteristic, parameters and definitions of actual features, comparing verification, measuring instrument, and calibration of size, distance, radius, angle, form and position of geometrical features, roughness profile, waviness profile, primary profile, surface imperfection and edges. The characteristics of the GPS, e.g. chain matrix model in each standard, a lot of new and mathematical terms, the size system, indications of dimensions other than linear sizes by using geometrical tolerances, uncertainty series and etc., are introduced in this paper. Based on the characteristics above, some challenges in the implementation of the GPS are analyzed. Therefore, a lot of in-depth adaptive studies of GPS in indications of the sizes and the dimensions other than linear sizes in the drawings, the evaluation models of uncertainties, the measuring techniques and instruments and etc. should be done, and the matching user manual should be provided to designers, manufactures, inspection personnel for the wide application of the GPS.
