摘　　要：总结和分析了我国现行既有幕墙检测相关规范中关于抽样方案的规定,以固定百分比抽样方案和运用《计数抽样检验程序》确定的抽样方案为例,分别计算了两种方案在不同检验批数量下的接收概率,并绘制了OC曲线,通过对OC曲线的分析得到:运用《计数抽样检验程序》等国家规范确定的抽样方案,具有判别能力强、抽样数量少、判别标准稳定等优势,在检测实践中应加强应用。According to the present specifications,sampling plans based on percentage sampling and National Sampling Inspection Standards（ NSIS） are widely used in testing of existing building curtain wall. On the basis of increasing inspection lot,acceptance probabilities of these two sampling methods are calculated,and OC curves are drawn and analyzed. The result indicates that the sampling plan based on NSIS is more discriminative,stable and economical,compared with the one based on percentage sampling. It is proposed that to apply the sampling plan based on NSIS in testing of existing building curtain wall.
