ADOPTED_FROM:EN ISO 17450-4:2018 This part of ISO 17450 gives general rules for building the GPS characteristics: size characteristics and geometrical characteristics. It defines a set of GPS characteristics (size characteristic and geometrical characteristic), which can be taken as default GPS characteristic or as special GPS characteristic, depending to the drawing indication, which is not a part of this standard. Moreover, this part of ISO 17450 presents a way to control the manufacturing process parameters by decomposition of a specified characteristic in a set of one or more characteristics.
