6、fication D 1193.6.Hazards6.1 Consult current OSHA regulations,suppliers MaterialSafety Data Sheets,and local regulations for all materials usedin this test method.7.Sampling and Handling7.1 Sample the material in accordance with PracticeD 3437.8.Procedure8.1 Measure 10 mL of pyridine specimen in a 1
7、00-mLmixing cylinder and dilute to 100 mL with water.Stopper andmix thoroughly by shaking.Let stand for 30 min at roomtemperature.8.2 Fill another cylinder with 100 mL of water and comparethe clarity of the specimen solution with that of the water.9.Report9.1 Report the appearance of the specimen so
