标准摘要
[中文适用范围]： 该方法包括目视检查豆子的外表面，以识别那些被昆虫损坏的豆子。 确定观察到的受损豆子的比例（百分比），如果可能，确定造成损害的昆虫种类。 根据由此确定的受损豆子的比例：估计给定概率下受损豆子的真实比例的置信极限；估计受损豆子的真实比例不超过给定值的概率。 附件 A 显示了受损豆子的插图。 附录 B 描述了实验室样品均匀性的测试。 [外文原描述]： The method consists in visual examination of the external surface of beans to identify those which have been damaged by insects. Determination of the observed proportion, as a percentage, of damaged beans and, if possible, identification of the species of insect responible to damage. From the proportion of damaged beans thus determined: estimation of the confidence limits of the true proportion of damaged beans for a given probability; estimation of the probability that the true proportion of damaged beans will not exceed a given value. An annex A shows illustrations of damaged beans. An annex B describes a test for homogenity of the laboratory sample.
