Lungs- A Mathematical-Statistical Method for the Determination 
SA SO of Metallographic Classification Series 
nahe 
eines The use of metallographic classification series for the evaluation of optically measurable 
ungen material quality standards is discussed and their characteristics are listed. An evaluation of 
erden the individual characteristics by their probability distribution and by the quality number 
derived therefrom is proposed. A guide line measuring scale is developed from the quality 
;chen- numbers of the particular characteristics and its usefulness is demonstrated on a practical 
e des example.
