Key Sentences extracted from text
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JB/T 6534、JB/T 6535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。
采取抽样检查方法时，可按JB/T 8687规定的合格判定数Ac（或A1、A2）和不合格判定数Re（或R1、R2）评定该批产品达到某一等级（合格品、一等品或优等品）。
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 JB/T 6534 and JB/T 6535, and the main assessment items and requirements shall comply with Table 1; the assessment items, indicators, and requirements for evaluating product quality grades shall comply with Table 2.
For batch products, the quality grade of individual products shall be evaluated first; the quality grade of an individual product shall meet all assessment item requirements of 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 are qualified; if the number of first-class or superior products accounts for more than 70% of the total and the remaining products are qualified, the batch can be rated as first-class or superior.
When using sampling inspection, the batch can be evaluated as reaching a certain grade (qualified, first-class, or superior) according to the acceptance number Ac (or A1, A2) and rejection number Re (or R1, R2) specified in JB/T 8687.
