本标准规定了防爆型刮刀卸料离心机的质量等级、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。
离心机产品除应符合JB/T 5284 和JB 8525 的规定外，各等级的考核项目和指标要求还应符合表1 的规定。
在检查中，有下列情况者定为不合格项目：a) 材料的物理性能、化学性能、探伤、动平衡等提不出原始记录和试验报告，现场又不能检测者；
按相应的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 explosion-proof scraper discharge 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 JB/T 5284 and JB 8525, the assessment items and indicator requirements for each grade of centrifuge product shall also comply with the provisions of Table 1.
During inspection, the following conditions are deemed as non-conforming items: a) failure to provide original records and test reports for physical properties, chemical properties, flaw detection, dynamic balancing, etc., and inability to test on site;
Inspection shall be carried out item by item according to the corresponding quality grading standard; a single machine under inspection can only be rated as a certain grade if all its indicators meet the requirements of that grade.
