Evaluation of Measurement Uncertainty for Plastic Retention Rate of Natural Rubber
The plastic retention rate of natural rubber was tested,and the uncertainty component of plastic retention rate in the test process was analyzed.The results showed that the measurement un-certainty of the plastic retention rate of natural rubber was mainly introduced by measurement repeat-ability,the temperature of the flat plate of the rapid plasticity meter,the compressed fixed thickness,pressure,test holding time,temperature of the aging oven,uncertainty or error of the timer,and rounding off of the values.The expanded uncertainty of the plastic retention rate of natural rubber was synthesized by using statistical formulas.
