The Organic Impurities Test is a widely used, simple procedure to determine the presence of organic compounds in fine aggregates. 

 

Samples are shaken in a special graduated bottle with a 3% sodium hydroxide solution then allowed to stand for 24 hours.  

If the resulting color of the liquid above the test sample is darker than a reference chart standard color, organic compounds may be present and further testing should be done. 

The Test Bottles are graduated in oz and ml and have watertight screw-on caps.
