将基于储存设计（在不同温度下储存样品不同时间段）的“等熵”测量的候选有证参比物质（CRM）稳定性试验的替代方法与使用参考时间或参考温度的稳定性研究的“经典”设计进行比较，该储存设计允许在同一时间（即研究结束时）进行所有测量。使用“等离子体”测量进行稳定性研究仅需要重复性条件，而经典设计需要重复性和长期再现性条件。因此，新的设计可以提高结果的质量。
An alternative method for stability testing of candidate certified reference materials (CRMs) utilizing "isochronous" measurements based on a storage design (storing samples at different temperatures for different time periods), which allows all measurements to be done at the same time, i.e. at the end of the study, is compared to "classical" designs of stability studies using reference time or reference temperature. The execution of stability studies using "isochronous" measurements only requires repeatability conditions, whereas classical designs require both repeatability and long term reproducibility conditions. Consequently, the new design allows the quality of results to be improved.
