Key Sentences extracted from text
本标准规定了单级、两级石油化工流程泵产品的质量等级、试验与检验方法和抽样、评定方法。
产品根据质量水平和使用价值分为合格品、一等品和优等品三个等级。
产品应符合GB/T 3215、JB/T 8095 的规定，其中主要考核项目及要求应符合表1 的规定，评定产品质量等级的考核项目、指标和要求应符合表2 的规定。
批量产品应首先进行单个产品的质量等级评定，判定单个产品的质量等级应符合该等级全部考核项目的要求，否则按达到的最低一项指标定等。
采取全数检查方法时，当所有产品达到合格品时，该批产品才能评为合格品；当达到一等品或优等品的数量占总数70%以上，且其余产品达到合格品时，该批产品才能评为一等品或优等品。
This standard specifies the quality grades, test and inspection methods, and sampling and evaluation methods for single-stage and two-stage petrochemical process pump products.
Products are divided into three grades: qualified product, first-class product, and superior product, based on quality level and use value.
Products shall comply with the provisions of GB/T 3215 and JB/T 8095, where the main assessment items and requirements shall comply with the provisions of Table 1, and the assessment items, indicators, and requirements for evaluating product quality grades shall comply with the provisions of Table 2.
For batch products, the quality grade of individual products shall first be evaluated; the quality grade of an individual product shall meet the requirements of all assessment items for that grade, otherwise it shall be graded according to the lowest indicator achieved.
When using full inspection, the batch can only be rated as qualified if all products meet the qualified grade; when the number of products reaching first-class or superior grade accounts for more than 70% of the total, and the remaining products meet the qualified grade, the batch can be rated as first-class or superior grade.

Changes from replaced version:
- 删除了“千小时效率平均降低值”考核项目
- 将“流量、扬程、汽蚀余量、润滑油渗漏、清洁度、泵用材料、涂漆和外观及包装”主要考核项目及要求从表2中移出列入表1中
- Deleted the assessment item 'average efficiency reduction per thousand hours'
- Moved the main assessment items and requirements for 'flow rate, head, NPSH, lubricating oil leakage, cleanliness, pump materials, painting and appearance, and packaging' from Table 2 to Table 1
