The new edition of the International vocabulary of metrology-basic and general concepts and associated terms (VIM) defines metrological traceability in a different way than was defined in the previous edition. The reference to an "unbroken chain of comparisons" is replaced by a "chain of calibrations." Calibrations, unlike comparisons, render possible an interpolation of the quantity values between indicated parameters where the calibration was performed. Calibrations of software may be performed using software-measurement standards as well. Furthermore, the traceability of quantities having a minor influence on the measurement result is not mandatory. As a consequence of these modifications, the traceability of gamma-ray spectrometric results can also be attained when gamma-ray spectrometry is implemented other than as a relative method.
新版《国际计量学词汇——基本和通用概念及相关术语》（VIM）对计量溯源性的定义与上一版不同。对上一版中“不间断的比较链”的提法，新版改为“校准链”。校准与比较不同，校准能够在进行校准的指示参数之间内插量值。软件校准也可以使用软件测量标准来进行。此外，对测量结果影响较小的量的溯源性并非强制要求。由于这些修改，当伽马射线能谱法不是作为相对方法实施时，也能够实现伽马射线能谱分析结果的溯源性。
