Equipment Performance Specifications

It is essential to verify that classing equipment meets minimum 

performance specifications. “Precision” refers to the ability of an 

instrument to produce the same measurement result time after time. 

“Accuracy” refers to how well an instrument measures a certain property 

in relation to its true value. 

Newly purchased equipment must pass a series of thorough tests before 

being accepted and put into 

operation. Specifications 

for the delivery of new 

equipment include the 

maximum allowable 

tolerances for precision 

shown in the table at right.

Furthermore, all instruments 

are evaluated annually, 

typically before each cotton 

season begins. Testing is 

done to verify both the 

precision and the accuracy of instrument measurements.
