17、ometrical 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 of line dependent on datum, form of surface independent of datum, form of surfa
18、ce 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 Annex B. Certain parts, when removed from their manufacturing environment, may d
19、eform 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 deformation is acceptable provided that the parts may be brought within the indicated
20、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 conventionally (in its free state condition), it may be necessary to assess the part wh
21、en 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 flexible material (such as rubber, plastics, etc.).

23、sioning and tolerancing non-rigid parts where restraining of features is required during verification of dimensions and tolerances specified on a drawing. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the
24、edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. ISO 1101:2004, Geometrical Product Specifications (GPS) Geometrical tolerancing Tolerances of form, orientation, location and run-out 3 Terms and definitions For the purpo
25、ses 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 geometrical tolerances on the drawing 3.2 free state condition of a part subjected only to the force of gravity 4 Basic principl
26、es 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 assembled, by applying pressure or forces not exceeding those which can be expected under normal assembly conditions. It is impo
27、ssible 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. If it is necessary to indicate the tolerance in the free state, the conditions under which the tolerance is to be achiev
28、ed (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 drawing by the added statement “ISO 10579-NR”, the restrained condition applies unless the dimensions and tolerances are
29、 qualified by the symbol , see Clause 5.
