High-speed fan-blending provides a means of homogenizing greasy-wool core samples before sub-sampling for yield-testing. The blending operation reduces the amount of retesting necessary by reducing the between-test-specimens variance of yield. Measurements are reported of the variance of yield between l-g sub-samples, which enables a partial separation to be made of the components of variance due to sub-sampling and testing as determined on larger (30-g) test specimens. High-speed fan-blending causes a reduction in both these components. There is a small, unexplained, and apparently systematic reduction in determinations of mean yield for wools blended in this manner. [ABSTRACT FROM AUTHOR] |
