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

This part uses the redrafting method to amend and adopt ISO 25178-71:2017 ``Geometrical Technical Specifications for Products (GPS) Surface Structure: Regional Method

Part 71: Software Measurement Standards:

Compared with ISO 25178-71:2017, 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 5436-2 with GB/T 19067:2, which is equivalent to the international standard (see Chapter 3);

* Replace ISO 17450-2 with GB/T 24637:2 modified to adopt international standards (see Chapter 3 and Chapter 6);

* Replace ISO 16610 (all parts) with GB /Z 26958 (all parts) equivalent to the international standard (see Chapter 3);

* Replace ISO 25178-2 with GB/T 33523:2 which is equivalent to the international standard (see Chapter 3, 5:1);

* Use JJF1001 instead of ISO /IEC Guide 99 (see Chapter 3):

This part is proposed and managed by the National Standardization Technical Committee for Product Geometric Technical Specifications (SAC/TC240):

1 Scope

This part of GB/T 33523 specifies the technique of S1 and S2 software measurement standards (etalon) used for software calibration of measuring instruments:

Language definition:

This part also specifies the file format of S1 software measurement standards:

This section applies to the surface structure standard chain based on the area method, the contour surface structure defined by the link G and the area surface structure measuring instrument

The measurement standard for calibration of metrological characteristics:

Note: In this section, the term "software gauge" is the abbreviation for software measurement standard S1:
