本标准规定了计量泵（以下简称泵）产品的质量等级、质量等级指标、抽样、等级评定以及检测方法。
按泵的综合质量分为合格品、一等品和优等品三个等级。
样品的各项质量指标全部达到本标准中某一等级的规定要求时，该样品才能评为该等级品，否则按其中某一项所达到的最低等级评定。
泵做抽样检测时，所有样品均达到某一等级时，该批泵才能评为该等级品，否则按其中某一样品的最低等级评定。
全数逐台检验时，其中一等品率应达到80%以上，其余泵不低于合格品时，才能相应地评为一等品；优等品率应达到80%以上，其余泵不低于一等品时，才能评为优等品。
This standard specifies the quality grades, quality grade indicators, sampling, grade evaluation, and test methods for metering pumps (hereinafter referred to as pumps).
According to the comprehensive quality of the pump, it is divided into three grades: qualified product, first-class product, and premium product.
When all quality indicators of a sample meet the requirements of a certain grade in this standard, the sample can be rated as that grade; otherwise, it is rated according to the lowest grade achieved by any one indicator.
When conducting sampling inspection of pumps, if all samples meet a certain grade, the batch of pumps can be rated as that grade; otherwise, it is rated according to the lowest grade of any sample.
When conducting 100% inspection of each pump, if the rate of first-class products reaches 80% or more and the remaining pumps are not lower than qualified products, the batch can be rated as first-class; if the rate of premium products reaches 80% or more and the remaining pumps are not lower than first-class products, the batch can be rated as premium.
