1.The degrees of freedom associated with the reproducibility estimate from this interlaboratory study for D1160 Biodiesel Precision for IBP are 22. Since the minimum requirement of 30 (in accordance with Practice D6300) is not met, users are cautioned that the actual reproducibility may be significantly different than these estimates. 2.The degrees of freedom associated with the reproducibility estimate from this interlaboratory study for D1160 Biodiesel Precision for 5 to 50 % are 18. Since the minimum requirement of 30 (in accordance with PracticeD6300) is not met, users are cautioned that the actual reproducibility may be significantly different than these estimates. 3.The degrees of freedom associated with the reproducibility estimate from this interlaboratory study for D1160 Biodiesel Precision for 60 to 95 % are 25. Since the minimum requirement of 30 (in accordance with PracticeD6300) is not met, users are cautioned that the actual reproducibility may be significantly different than these estimates. 4.The degrees of freedom associated with the reproducibility estimate from this interlaboratory study for D1160 Biodiesel Precision for FBP are 14. PracticeD6300does not recommend publishing precision estimates with degrees of freedom less than 15 as the reliability of such estimates is highly questionable. 5.The precision statements were derived from a 2012 interlaboratory cooperative test program.A total of nine participating laboratories using various D1160 automated, automatic, or manual apparatus analyzed blind replicates of eleven sample sets comprised of eight specification grade biodiesel (derived from soy, canola, tallow, and yellow grease), two mixed blends of biodiesel (soy and tallow), and a mustard oil. The distillation range was from 274 to 400°C. Information on the type of samples and their average boiling points are in the research report. [ Last edited by 蓝色游鱼归情 on 2014-1-4 at 23:20 ] |

1.根据对IBP的D1160生物柴油精度跨实验室研究的估计，与再现性相关的自由度为22.因为并没有达到最低要求30（依照PRACTISE D6300），使用者应当注意实际的再现性可能与估计值有显著的差别； 2.根据对5%至50%的D1160生物柴油精度跨实验室研究的估计，与再现性相关的自由度为18.因为并没有达到最低要求30（依照PRACTISE D6300），使用者应当注意实际的再现性可能与估计值有显著的差别； 3.根据对65%至95%的D1160生物柴油精度跨实验室研究的估计，与再现性相关的自由度为25.因为并没有达到最低要求30（依照PRACTISE D6300），使用者应当注意实际的再现性可能与估计值有显著的差别； 4.根据对FBP的D1160生物柴油精度跨实验室研究的估计，与再现性相关的自由度为25.PRACTISE D6300不推荐公布自由度少于15的精度估计，因为这些估计的可靠性是高度值得怀疑的； 5.此精度报告来自于2012年跨实验室联合测试项目。总共9家参与实验室使用多种D1160自动或手动的设备分析了11组平行样品，其中包括8种规格的生物柴油（来源于大豆、油菜籽、牛油、黄油）和2种混合生物柴油（大豆和牛油），以及芥末油。馏程在274到400摄氏度之间。这些样品的信息和它们的平均沸点在研究报告里。 |
