Scope

This part of GB/T 38762 describes the uncertainty caused by the application of dimensional specifications to control dimensions other than linear and angular dimensions, and the benefits of using geometric specifications to control the above dimensions. Dimensional tolerances can be specified as ± tolerances or geometric specifications. Uncertainties arising from the use of ± tolerances for dimensions other than linear dimensions (for example, the independent tolerances and general tolerances mentioned in GB/T 1804 and GB/T 6414), are explained in Appendix A. Note 1: The legends in this section are simplified and are only interpretations of the content of the text, and do not reflect actual usage. Therefore, the legend is only a simplified annotation of the relevant guidelines. Note 2: Regarding the marking of dimensional tolerances, see the following:. ——GB/T38762.1 linear dimension; ——GB/T38762.3 angular dimension; ——ISO2538 1 and ISO2538 2 wedge;
