目的 通过对啤酒瓶的抗冲击项目进行重复性测试，分析质量水平与公布数据之间的差异原因，探求适合持续监管和减少异议复检的对策。方法 通过在同等条件下，对99组不同地区、不同厂家、不同规格的样品进行连续检测抗冲击指标，统计该项目结果的再现性。结果 抗冲击项目在相同条件下的连续检测，不论是通过组还是未通过组，其结果再现性都很低。同理，监督工作中如运用备样进行复检，并以复检结果作为最终定论，可造成大概率的结论否定，给监管工作增加难度，使承检机构出具报告处于两难境遇。结论 啤酒瓶抗冲击指标作为重复性很低的破坏性试验项目，不适合在监督工作中的备样复检，应严格规范试验过程，保留现场试验影像记录等方式，作为异议复检的证明资料对策运用，不但要能便于持续性监管，避免自我否定，而且还能维护各方的权益，确保监督工作的公信度。

The work aims to analyze the reasons for the difference between the quality level and the published data through the repetitive test of impact resistance items of beer bottles and explore the countermeasures suitable for continuous supervision and reducing the re-inspection. Through testing 99 groups of samples from different regions, manufacturers, and specifications under the same condition, the reproducibility of item results was counted. The result reproducibility of continuous testing of anti-impact items under the same conditions, whether passed or failed, was very low. Similarly, if the spare samples were used for re-inspection in supervision, and the re-inspection result was taken as the final conclusion, it would cause a high probability of negative conclusion, which may increase the difficulty of supervision, and put the inspection institution in an embarrassing context when issuing the report. As a destructive test item with low repeatability, the impact index of beer bottles is not suitable for re-inspection of spare samples. The test process should be strictly standardized and the image records of field test should be kept to be used as the proof data of objection of re-inspection. It should facilitate continuous supervision and avoid self-denial, but also safeguard the rights and interests of all parties and ensure the credibility of supervision.
