This section applies to linear dimensions of statistical process control applications. Especially those with a high tolerance level with the size, also have bilateral norms applicable to their limits and quality characteristics of metrological applications of statistical process control.

GB /Z20308 Geometrical product specifications (GPS) master plan (GB /Z20308-2006, ISO /T R14638..1995, MOD)3 statistical tolerance value formThe statistical tolerance of process quality indicators is determined by the application of specific statistical tolerances. Both upper and middle are dimensionless normalized numbers Value, the lower is the value of the dimension. 3.1 Process Quality Indicators statistical tolerance value The statistical tolerance values (P * d, P * c, P *ql) of the process quality indicators are expressed as a percentage and selected by the recommended form. Generally take a decimal point Bit or two. Of these, Pd, which requires exceptionally high, can be expressed in parts per million (10-6). 3.2 Standardized two-dimensional statistical tolerance value The two-dimensional statistical tolerance values are expressed as dimensionless numbers in (C * p, 犽 ) and (C * p, δ *) arrays whose sizes are defined by the upper direct mass index Standard or indirect quality indicators. 3.3 Dimensional two-dimensional statistical tolerance values The statistical tolerance values based on the two-dimensional statistical parameter interface with the actual dimensions are expressed by the values in the array (σ, Δ) whose size is given by Standardized two-dimensional statistical tolerance value conversion. 3.4 General requirements of the quality level and the value of the statistical tolerance Statistical tolerances General requirements of the quality level can be 3σ and 4σ quality level of recommendation, according to industry and product characteristics to choose one of them As the default statistical tolerance common requirements, the implied values of the statistical tolerance shown in Table 1.
