THE VARIABILITY OF RESULTS OBTAINED BY TESTING INDEX PROPERTIES OF SOILS (IN CZECH)

EACH OPERATOR OF A GROUP OF SIX OPERATORS TESTED THE SAME SOIL SAMPLE TO DETERMINE GRAIN-SIZE DISTRIBUTION, SPECIFIC GRAVITY, PLASTIC AND LIQUID LIMIT. THE FOLLOWING CAN BE CONCLUDED FROM THE SCATTER OF THE MEASURED VALUES: GRAIN-SIZE DISTRIBUTION-VARIABILITY OF RESULTS DEPENDS MAINLY ON THE PREPARATION OF THE SAMPLE; SPECIFIC GRAVITY-MEASURED VALUES CAN DIFFER FROM MEAN VALUES UP TO ONE PER CENT OF THE MEAN VALUES; LIQUID LIMIT--FOR CLAY THE MEASURED VALUES WITH A PROBALITY OF 70 PER CENT DO NOT DIFFER FROM MEAN VALUE MORE THAN FIVE PER CENT OF THE MEAN VALUE; AND PLASTIC LIMIT-FOR CLAY THE MEASURED VALUES WITH A PROBALITY OF 70 PER CENT DO NOT DIFFER FROM THE MEAN VALUE MORE THAN 10 PER CENT OF THE MEAN VALUE. /AUTHOR/
