19、 iv ISO 2010 All rights reservedIntroduction This International Standard is a geometrical product specification (GPS) standard and is to be regarded as a global GPS standard (see ISO/TR 14638)4. It influences chain links 1, 2 and 3 of the chain of standards on form of line independent of datum, form
20、 of line dependent on datum, form of surface independent of datum, form of surface dependent on datum, orientation, location, circular run-out and total run-out in the general GPS matrix. For more detailed information on the relation of this standard to other standards and the GPS matrix model, see
21、Annex B. Certain parts, when removed from their manufacturing environment, may deform significantly from their defined limits owing to their weight, flexibility or the release of internal stresses resulting from the manufacturing processes. These parts are defined as “non-rigid parts” and the deform
22、ation is acceptable provided that the parts may be brought within the indicated tolerance by applying reasonable force to facilitate inspection and assembly. Depending on the design function and the parts interface with its mating components, instead of, or in addition to, assessing the part convent
23、ionally (in its free state condition), it may be necessary to assess the part when subject to restraint that is no greater than those accepted in the assembled condition. Parts in this category include both those of inherently rigid material (such as thin metal parts) and those of inherently flexibl
24、e material (such as rubber, plastics, etc.).

28、GPS) Geometrical tolerancing Tolerances of form, orientation, location and run-out 3 Terms and definitions For the purposes of this document, the following terms and definitions apply. 3.1 non-rigid part part which deforms to an extent that in the free state is beyond the dimensional and/or geometri
29、cal tolerances on the drawing 3.2 free state condition of a part subjected only to the force of gravity 4 Basic principles The distortion of a non-rigid part must not exceed that which allows the part to be brought within specified tolerances for verification and positioning at assembly, or assemble
30、d, by applying pressure or forces not exceeding those which can be expected under normal assembly conditions. It is impossible to avoid the effect of natural forces such as gravity, but the extent of distortion may depend upon the orientation of the part and condition of the part in the free state.
31、If it is necessary to indicate the tolerance in the free state, the conditions under which the tolerance is to be achieved (i.e. the direction of gravity, conditions in which it is to be supported, etc.) may have to be indicated in a note, as shown in Annex A. For non-rigid parts, identified on the
32、drawing by the added statement “ISO 10579-NR”, the restrained condition applies unless the dimensions and tolerances are qualified by the symbol , see Clause 5.
