Evaluation of Uncertainty in Measuring Starch Content in Starch Based Plastic Shopping Bags Using Thermogravimetric Method
The content of starch in starch based plastic shopping bag was measured by thermogravimetric method,and the uncertainty components affecting the measurement were analyzed and evaluated.The results showed that when the starch content was 15.37％,the extended uncertainty was 0.22％(k=2).At the same time,due to the relative contribution of repeatability components,inspection and testing institutions should pay attention to instru-ment maintenance and personnel training.
