如何对计量器具的校准结果进行评价

一、计量校准的概念及目前存在的误区按照JJF1001-2011《通用计量术语及定义》之4.10的表述,校准是在规定条件下的一组操作,其步是确定由测量标准提供的量值与相应示值之间的关系,第二步则是用此信息确定由示值获得测量结果的关系,这里测量标准提供的量值与相应示值都具有测量不确定度。

一些计量器具的使用者认为,仪器经过校准后就准确了,当校准人员向他(她)说明仪器示值超差后,总是认为计量校准就是要把仪器“校”准了才算是校准,如果仪器不准就应该“校”准了,否则对所做的校准工作不予认可,在需要签字的确认单上不签字,造成双方对立。

能否使用CNAS标志在我国是一个校准实验室是否通过了ISO/IEC17025:2005标准认可的第三方证明,由CNAS组织给出,同时还是一个在亚太地区组织中得到互认的说明,其优点不言而喻。但是,由于认可标准是通用的管理性和技术性要求,某一计量器具的校准证书上可以使用CNAS上海11选5认可标志是因为该计量器具的校准能力获得了审核通过(有一定的适用要求),而通过审核的先决条件是有相应的校准依据和可提供量值溯源的标准器,而校准依据通常是、行业、地方的校准规范或检定规程。当涉及该计量器具没有校准依据时,就无法进行认可,只有编制了具有说服力的自编校准方法后才可以通过,这就会造成部分计量器具暂时无法获得CNAS的认可,但并不代表校准实验室不具有校准能力、不能出具校准证书。

-MPE+U(y)≤EMPE-U(y) (1)

式中:U(y)——具有一定包含概率的测量结果的不确定度;E——示值误差;MPE上海11选5——示值超大允许误差。

(2)按判定条件的1/3~1/10的比例选择测量标准,或者说测量标准的扩展不确定度或超大允许误差为被检计量器具超大允许误差的1/3~1/10,这时测量标准的不确定度对测量结果不确定度的影响就可忽略,即测量结果受测量标准的影响可不再考虑,其具体原因可通过测量标准的不确定度和被校准计量器具的不确定度的相互关系说明。
通常,测量结果的测量不确定度Ut至少包含测量标准的不确定度Us和被校准计量器具的不确定度Ux两项,即时,                    对测量结果的影响<0.06;当Us/Ux=1/10时,1.005Ux, Us对测量结果的影响<0.005。

同时JJF1094-2002《测量仪器特性评定》之5.3.1.4明确规定:示值误差的测量不确定度U95与被评定测量仪器的超大允许误差的当然值MPEV之比小于或等于1/3时,进行符合性判定时,则不考虑示值误差的测量不确定度的影响,当这种评定是用于型式评价和仲裁鉴定时,必要时U95MPEV之比也可取小于或等于1/5。对于U95的确定,也可以用包含因子k=2的扩展不确定度U代替。

计量器具的校准能力需要在硬件和软件两方面进行保证,其硬件包含满足量值溯源要求的测量标准器具(合格并在有效期内)、相应的辅助设备(涉及量值时应溯源)、符合要求的技术人员以及开展校准工作所必备的环境条件和控制措施;软件则包含必要的管理制度和程序文件规定,当满足了这些要求时该实验室即具有了相应的校准能力。
如果实验室在软硬件的准备和配置上严格依据ISO/IEC17025:2005标准的规定,并经过CNAS审核认可,遵守CNAS的相应要求,则校准实验室所出具的校准证书就可以使用CNAS的认可标志,它是独立的第三方能力评价说明,有助于计量校准的需求方寻找合格的校准服务机构,但并不是说没有通过CNAS认可的校准实验室就不具有相应的校准能力,因为是否具有校准能力与实验室自身的能力建设关联,与CNAS认可没有直接关系。

在校准服务中,如果校准的需求方有评审校准实验室的方案,也可直接对提供校准服务的实验室进行第二方审核,以确认实验室是否具有提供校准服务的能力,这是很多国外大型跨国公司在选择校准服务机构之前所做的一项主要工作。国内许多校准实验室在为这些跨国公司提供校准服务时,都会受到这样的第二方审核,并且这种第二方审核可能随时会进行。一般情况下,第二方审核更关注对校准实验室软、硬件方面的具体要求,其审核的严苛程度会高于第三方的审核。虽然该校准实验室不一定通过了CNAS的审核认可,但当获得第二方认可后同样可以为其提供校准服务,而不再拘泥于CNAS的审核说明。
