摘要
从认可实验室管理的角度,阐述了化学标准物质期间核查的目的和意义。化学标准物质常见期间核查方法有实验室比对或能力验证、标准物质间比对、控制图法、允差法及标定法。结合实例介绍了化学标准物质期间核查的具体过程,为开展化学标准物质期间核查工作提供参考。
From the accredited laboratory management perspective, the purpose and significance of the chemical reference material period verification were elaborated. The common methods for chemical reference material period verification were laboratory comparisons or proficiency tests, comparison of standard substancewas, control chart method, tolerance method and calibration method. The specific process was introduced by concrete instances, which would guide to the chemical reference material period verification work.
