【 摘 要 】

In the sampling test, in the absence of actual data of the eigenvalues, combined with the actual conditions of the project, the total coefficient of variation under various distribution types can be used to estimate the sample size required for sampling. The article studies the sampling inspection of the strength of small batches of precast concrete components, and obtains the overall coefficient of variation under the normal distribution type, and then it can calculate the sample size required for different total amount of corresponding sampling inspection.
