Foreword

Appendix A and Appendix B of this guidance document are informative appendices. This Guidance Document is proposed and managed by the National Technical Committee for Standardization of Product Dimensions and Geometrical Specifications. This guiding technical document was drafted. China Machine Productivity Promotion Center, Zhongyuan Institute of Technology, Xi'an Jiaotong University. The main drafters of this guidance document. Li Xiaopei, Zhao Zexiang, Qiao Xuetao, Zhao Zhuoxian. Product Geometry Specifications (GPS) Linear and angular dimensions and tolerances Note. +/- Limit specifications Step size, distance, Angle size and radius

1 Scope

This guidance document defines the ± limits of step size, distance, angular dimension and radius when the function is related to only two elements specification. This guidance document is for drawings marked "GB /Z24638" only.

4 linear dimensioning

4.1 Overview Linear dimensioning applies to dimensioned and distance-filled tolerances between two ideal elements, otherwise GB/T 1182 applies. 4.2 The distance between two parallel planes Dimensioning (step size dimensioning) The step size refers to the distance between two parallel planes (elements) outside the entity that face the same (see Figure 1). Figure 1 Step size A plane in two parallel planes serves as the basis for the evaluation. For the purposes of this document, the step size refers to the fitting plane where the base of the assessment surface is in contact with the other surface and parallel to the base surface of the assessment
