    7.1.5.2、测量溯源

    当要求测量溯源时,或组织认为测量溯源是信任测量结果有效的基础时,测量设备应:

    a)对照能溯源到国际或国家标准的测量标准,按照规定的时间间隔或在使用前进行校准和(或)检定,当不存在上述标准时,应保留作为校准或验证依据的成文信息;

    b)予以识别,以确定其状态;

    c)予以保护,防止由于调整、损坏或衰减所导致的校准状态和随后的测量结果的失效。

    组织应建立、实施并保持一个对需要校准或检定的监视和测量设备进行召 回的过程。

    组织必须保持一份监视和测量设备的清单。清单应包括设备型号、唯一性标识、位置、校准和检定方法、检查频率和接收准则。

    注:监视和测量设备包括但不限于:试验硬件、试验软件、自动试验设备(ATE)和用于生成检验数据的绘图仪,也包括用于提供产品符合证据的个人拥有的和顾客提供的设备。

    监视和测量设备的校准或检定应在适宜环境条件下实施。

    当发现测量设备不符合预期用途时,组织应确定以往测量结果的有效性是否受到不利影响,必要时应采取适当的措施。

    7.1.5.1、Measurement Traceability

    When measurement traceability is a requirement, or is considered by the organization to be an essential part of providing confidence in the validity of measurement results, measuring equipment shall be:

    a. calibrated or verified, or both, at specified intervals, or prior to use, against measurement standards traceable to international or national measurement standards; when no such standards exist, the basis used for calibration or verification shall be retained as documented information;

    b. identified in order to determine their status;

    c. safeguarded from adjustments, damage, or deterioration that would invalidate the calibration status and subsequent measurement results.

    The organization shall establish, implement, and maintain a process for the recall of monitoring and measuring equipment requiring calibration or verification.

    The organization shall maintain a register of the monitoring and measuring equipment. The register shall include the equipment type, unique identification, location, and the calibration or verification method, frequency, and acceptance criteria.

    NOTE: Monitoring and measuring equipment can include, but are not limited to personally owned and customer supplied equipment used to provide evidence of product and service conformity.

    Calibration or verification of monitoring and measuring equipment shall be carried out under suitable environmental conditions (see 7.1.4).

    The organization shall determine if the validity of previous measurement results has been adversely affected when measuring equipment is found to be unfit for its intended purpose, and shall take appropriate action as necessary.
