---Deleted the "sieve hole size between the maximum size (w X) and the number of sieve holes between the middle size (w Z)
Quantity" calibration item;
--- Deleted the "Basic Size Determination" calibration item;
--- Modified the calibration method of "maximum size of sieve hole" and "average size of sieve hole";
---Modified the "Uncertainty assessment of the measurement results of the mesh size of the wire mesh test sieve";
--- Move the metrological characteristics of the test sieve to Appendix A;
---Delete the technical requirement "Intermediate deviation in the mesh size deviation of the wire mesh test sieve";
--- Added the technical requirements of "Maximum standard deviation of wire mesh test sieve mesh size":
