This part is Part 1 of GB/T 33523:

This section was drafted in accordance with the rules given in GB/T 1:1-2009:

This part uses the redrafting method to modify and adopt ISO 25178-1:2016 "Geometrical Technical Specifications for Products (GPS) Surface Structure Area

Law Part 1: Representation of Surface Structure:

Compared with ISO 25178-1:2016, this part has technical differences: The corresponding technical differences and their reasons are as follows:

---Regarding normative reference documents, this section has made adjustments with technical differences to adapt to my country's technical conditions and adjustments:

The situation is collectively reflected in Chapter 2 "Normative Reference Documents", and the specific adjustments are as follows:

* Replace ISO 1101 with GB/T 1182, which is modified to adopt international standards (see Chapter 3 and Chapter 8);

* Replace ISO 81714-1 (see Appendix A) with GB/T 16901:1 which is modified to adopt international standards;

* Replace ISO 16792 (see Chapter 3 and Chapter 8) with GB/T 24734 (all parts) that is not equivalent to international standards:

This section has made the following editorial changes:

---In the "Scope" chapter, add "Appendix A of this part gives the scale and size of graphic symbols; Appendix B gives a clear table

The marking of the surface structure requirements; see Appendix C for examples of the surface structure requirements of the marked area; refer to the recommended procedures for indicating intersecting planes

Appendix D; For the ISO special specification elements of the regional surface structure, please refer to Appendix E "This section applies to the regional surface structure of the workpiece

Mark":

1 Scope

This part of GB/T 33523 specifies the use of graphical symbols to indicate areas in product technical documents (such as drawings, specifications, contracts, and reports):

The rules of the domain surface structure:

Appendix A of this part gives the proportions and dimensions of the graphic symbols; Appendix B gives the labels for clear surface structure regulations; the label area

See Appendix C for examples of domain surface structure requirements; refer to Appendix D for recommended procedures for indicating intersecting planes; ISO special regulations for area surface structures

See Appendix E for fan elements:

This section applies to the marking of the regional surface structure of the workpiece:
