| Abstract: | Certified reference material of rigid PVC for oxygen index was developed. The preparing technology, homogeneity and stability examination, uncertainty of certification of the certified reference material were analyzed. The results showed that the certification values are normal distribution while data from different labs were equal degree of precision. The homogeneity and stability is satisfactory. The standard value is 43.6%, and the expanded uncertainty is 0.7%. |
