为保证国内顶焦度量值的准确一致,了解各实验室的装置水平,保证顶焦度量值传递的溯源准确性,中国计量科学研究院组织并实施了验光镜片顶焦度示值校准的能力验证计划(以下简称“计划”)。本次计划要求各参加实验室依据JJG579-2010《验光镜片箱》检定规程,按照日常校准程序校准验光镜片的球镜顶焦度示值。共有52家参加实验室提交了结果,其中已获认可实验室为44家,占参加实验室总数的83%。参加实验室包括13家省级计量技术机构、34家市级计量和质检技术机构、4家区级计量技术机构和1家军区联勤部药品仪器检验所。在总计260个校准结果中不满意结果为2个,仅占0.77%,有2家实验室的结果为不满意,占参加实验室的3.85%。
In order to ensure the accuracy and consistency of the domestic top-of-focus measurements, understand the level of the devices in each laboratory and ensure the traceable accuracy of the transmission of the top-of-focus values, CAE has also organized and implemented the capability verification of indication-point calibration of optometric lenses Plan (hereinafter referred to as “plan”). The plan requires each participating laboratory based on JJG579-2010 “optometric lens box” verification procedures, according to the routine calibration routine calibration refraction lens spherical vertex power indication. A total of 52 participating laboratories submitted the results, of which 44 have been accredited laboratories, accounting for 83% of the total number of participating laboratories. The participating laboratories include 13 provincial-level metrology institutes, 34 municipal-level metrology and quality inspection technical institutes, 4 district-level metrology institutes, and 1 military area joint logistics department drug instrument inspection institute. Out of a total of 260 calibration results, 2 were unsatisfied, accounting for only 0.77%. The results of 2 laboratories were unsatisfactory, accounting for 3.85% of the participating laboratories.
