Abstract

To examine a repeatability of classification of size deviation and maximum deviation of the size test for raw silk, I take to computer simulation experiment of twice test for the same lot.
Difference of classification of size deviation are almost within 1 grade, but according to the ratio of variance of among skeins are enlarge, difference of 2 grade are appeared. Difference of classification of maximum deviation are more big, according to the ratio of variance of among skeins are enlarge, difference of 3 grade are barely appeared.
The ratio of differance of twice classification of size deviation are 0.25 to 0.50, and 1.38 times of the ratio of error in classification. The ratio of differance of twice classification of maximum deviation are 0.41 to 0.58, and 1.34 times of the ratio of error in classification.
