一文讲透软测实验室内部比对、实验室间比对、能力验证与测量审核

为了确保软件测试实验室测试数据的准确性、可靠性以及检测报告的质量水平,CNAS软件检测实验室需要建立一套完整的质量控制程序,确保出具的软件测试结果的误差被控制在允许限度内。质量控制又分为内部质量控制与外部质量控制。

 

内部质量控制可以通过以下方式来实现:使用标准物质或质量控制物质;使用其他已校准能够提供可溯源结果的仪器;测量和检测设备的功能核查;适用时,使用核查或工作标准,并制作控制图;测量设备的期间核查;使用相同或不同方法重复检测或校准;留存样品的重复检测或重复校准;物品不同特性结果之间的相关性;审查报告的结果;内部比对;盲样测试。外部比对主要通过实验室间比对、测量审核和能力验证来实现。

 

在这其中有几个重要的概念,实验室内部比对、实验室间比对、能力验证和测量审核,下面我们就来解读一下,这几个概念的异同点。

 

实验室外部比对、能力验证和测量审核都属于外部质量控制的范畴。都是为了确保实验室维持较高的检测水平而对其能力考核、监督和确认的一种验证活动。二者采用的的方法差别不大,不一样的地方在于,实验室间比对可以由实验室自己去组织,能力验证则是需要得到CNAS承认的机构才能组织,并且每年能力验证的时间也是有能力验证提供机构统一公布。能力验证活动必须对参加对象进行能力评价,而实验室间比对往往只需要得到某个特定的结论。而测量审核测量审核是对一个参加者进行“一对一”能力评价的能力验证计划。由于是“一对一”,一般费用相对也会更高一些。

 

而实验室内部比对指的是利用实验室内部检测人员间的比对来确定实验室能力的活动,是评价检测人员是否具有胜任其所从事检测工作能力的方法。

 

以上就是我们为大家整理的CANS软件测试实验室内部比对、实验室间比对、能力验证与测量审核这几个概念的异同之处,如需详细的计划方案可私信我或在评论区交流讨论。
