ISO 25178-71:2017定义了用于验证测量仪器软件的S1型和S2型软件测量标准（标准具）。它还定义了S1类软件测量标准的文件格式，用于校准通过面积法测量表面纹理的仪器，如面积表面纹理标准链中定义的chain link G。 注:在整个ISO 25178-71:2017中，术语“softgauge”被用作“S1型软件测量标准”的替代品。

ISO 25178-71:2017 defines Type S1 and Type S2 software measurement standards (etalons) for verifying the software of measuring instruments. It also defines the file format of Type S1 software measurement standards for the calibration of instruments for the measurement of surface texture by the areal method as defined in the areal surface texture chain of standards, chain link G. NOTE Throughout ISO 25178-71:2017, the term "softgauge" is used as a substitute for "software measurement standard Type S1".
