可追溯性对CRM意味着什么？
计量词汇将可追溯性定义为测量结果或标准值的一种特性，通过一系列不间断的比较，可将其与规定的参考文献（通常是国家或国际标准）联系起来，所有这些都具有规定的不确定性。更实际的说法是，这意味着将结果固定在不会随时间和地点变化的标准上，以便使测量结果具有可比性。因此，CRM的认证值应可追溯到此类国际公认标准，最好是国际单位制（SI）。使用CRM是证明可追溯性的一种方便方式。
What does traceability mean for CRMs?
The Vocabulary of Metrology defines traceability as a property of the result of a measurement or the value of a standard whereby it can be related to stated references, usually national or international standards, through an unbroken chain of comparisons all having stated uncertainties. In more practical terms this means to anchor the results to standards which do not change over time and place in order to make measurement results comparable. Consequently, the certified value(s) of a CRM shall be traceable to such internationally accepted standards, preferably to the International System of Units (SI). Use of a CRM is a convenient way to demonstrate traceability.
