Abstract��According to the theory of the measurement uncertainty�� the bending strength was tested for the single component polyurethane resin �� and the results were analyzed to determine the sources of the uncertainty. Each component of uncertainty was calculated�� the component uncertainty results were obtained. And the effect of the uncertainty component on the determination results was analyzed�� which indicated that the repeatability measurement was the main source of the uncertainty. Thus�� the uncertainty analysis provided guidance on how to reduce the error of the experimental results.
