本标准规定了三足式离心机的质量等级、试验方法和抽样与评定方法。
离心机产品根据其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。
离心机除应符合GB/T 13755、GB/T 13756 和JB 8525 的规定外，各等级考核项目和指标要求还应符合表1 的规定。
抽样检查的离心机应是通过鉴定、具备批量生产条件、并经制造厂自检合格的产品。
按相应质量分等标准逐条逐项进行检查，被抽检单机各项指标均达到某等级指标要求，才能评为该等级。
This standard specifies the quality grades, test methods, and sampling and evaluation methods for three-column centrifuges.
Centrifuge products are divided into three grades: qualified product, first-class product, and superior product, based on their quality level and use value.
In addition to complying with GB/T 13755, GB/T 13756, and JB 8525, centrifuges shall also meet the assessment items and index requirements for each grade as specified in Table 1.
The centrifuges selected for sampling inspection shall be products that have passed appraisal, are capable of batch production, and have passed the manufacturer's self-inspection.
Inspection shall be carried out item by item according to the corresponding quality grading standard; a single machine sampled can only be rated at a certain grade if all its indicators meet the requirements of that grade.
