Note 6 traceability to national measurement standards does not necessarily require the use of the national metrology institute of the country in which the laboratory is located 注6 :对国家测量标准的溯源性不要求必须使用实验室据国的国家计量院
Note 8 the unbroken chain of calibrations or comparisons may be achieved in several steps carried out by different laboratories that can demonstrate traceability 注8 :不间断的校准或比较链,可以通过不同的、能证明溯源性的实验室以过若干步骤来实现
In vitro diagnostic medical devices - measurement of quantities in biological samples - metrological traceability of values for catalytic concentration of enzymes assigned to calibrators and control materials 体外诊疗装置.生物样品的定量测量.校准仪和控制系统指定酶的催化浓度的测量溯源性
In vitro diagnostic medical devices - measurement of quantities in biological samples - metrological traceability of values for catalytic concentration of enzymes assigned to calibrators and control materials 体外诊断医疗器材.生物试样的数值测量.校准仪和控制材料赋值的酶催化浓度计量溯源性
Scl has set up primary standards in some of its measurement fields . these primary standards provide the ultimate traceability for the reference standards and measuring equipment used by scl in the respective fields 。 scl在一些测量领域设置了基准。这些基准在其领域为参考标准和测量器材提供最终的溯源性。
Note 5 when the terms “ international standard ” or “ national standard ” are used in connection with traceability , it is assumed that these standards fulfil the properties of primary standards for the realization of si units 注5 :当“国际标准”和“国家标准”与溯源性关联使用时,则是假定这些标准满足了实现si单位基准的性能
From the view of uncertainty the chain of traceability and its continuity of chemical ingredients , the function of the crms in chemical analysis and the realization of the traceability of the value of the crms are discussed 从不确定度的角度论述了化学成分量值的溯源链及其连续性；有证参考物质在化学测量中的作用以及有证参考物质量值溯源性的实现。
Indeed , a recent european union directive requires all fresh agricultural produce imported into the eu to have full traceability capability , and the us has recently introduced a similar requirement for a wide range of fresh and processed food products 事实上，欧盟最近发出指示要求所有出口到欧盟的新鲜农产品要有完善的可溯源性，美国最近也对大范围的新鲜和加工食品提出了类似要求。
For measurement fields where primary standards have not yet been set up , scl will wherever possible , send the appropriate reference standards and transfer standards to overseas primary standards laboratories of recognised international repute and authority , such as npl of uk , nist of usa , ptb of germany , for regular recalibration in order to provide correct traceability to the si and primary standards of measurement 在还未设置基准的测量领域， scl在可能的情况下，将把适当的参考标准和传递标准送交国外具国际声望和权威的主要标准实验室校正，譬如英国的npl ，美国的nist和德国的ptb ，以提供正确的溯源性。在一些情况下，参考标准将被送往一些经检定的校正实验室进行校正。
