为了建立密度和粘度标准，对液态铝和铁的密度和粘度的现有实验数据进行了严格的检查。所有的实验数据已被归类为主要和次要数据，根据测量质量规定的一系列标准。铝和铁密度的建议标准参考相关性的特征在于在95%置信水平下的标准偏差分别为0.65%和0.77%。密度绝对值的总体不确定性估计为铝的+/- 0.7%和铁的0.8%，这比最乐观的说法要差，但认识到不同方法之间无法解释的差异。铝和铁的粘度的标准参考相关性的特征在于在95%置信水平下的标准偏差分别为13.7%和5.7%。两种金属粘度绝对值的不确定性被认为不大于用不同技术进行的测量之间的离散度，因此可以说在铝的情况下为+/- 14%，在铁的情况下为+/- 6%。(c)2006年，美国物理学会。
The available experimental data for the density and viscosity of liquid aluminum and iron have been critically examined with the intention of establishing a density and a viscosity standard. All experimental data have been categorized into primary and secondary data according to the quality of measurement specified by a series of criteria. The proposed standard reference correlations for the density of the aluminum and iron are characterized by standard deviations of 0.65% and 0.77% at the 95% confidence level, respectively. The overall uncertainty in the absolute values of the density is estimated to be one of +/- 0.7% for aluminum and 0.8% for iron, which is worse than that of the most optimistic claims but recognizes the unexplained discrepancies between different methods. The standard reference correlations for the viscosity of aluminum and iron are characterized by standard deviations of 13.7% and 5.7% at the 95% confidence level, respectively. The uncertainty in the absolute values of the viscosity of the two metals is thought to be no larger than the scatter between measurements made with different techniques and so can be said to be +/- 14% in the case of aluminum and +/- 6% in the case of iron.
