Abstract: | The Canadian Certified Reference Materials Project has amended its procedure in interla-boratory certification programs. The reasons for reducing to one from two the number of bottles of a candidate reference materials submitted to each participating laboratory are discussed. The effect of the smaller number of results of the one-bottle approach to be expected on the certified value and 95% confidence interval is shown to be minor. |
