| Abstract: | The developing process of the certified reference material of polyethylene melt flow rate was introduced. The certified reference material of melt flow rate was prepared by polymer blend technique. The certification was conducted by the cooperation of 6 laboratories, the certification method is GB/T 3682 -2000. The homogeneity and stability of the certified reference material of polyethylene melt flow rate developed by polymer blend technique are good, the result of the certified value is accurate and reliable. The stable period is more than one year, the certified value is 20. 10 g/(10 min) and expanded uncertainty is 0.46 g/(10min). |
