Key Sentences extracted from text
压缩机产品根据其质量水平和使用价值，分为合格品和一等品两个等级。
压缩机产品除符合JB/T 6428 规定外，考核项目和各等级的指标按表1 的规定。
压缩机的容积流量不低于额定值的95%。
压缩机体的振动烈度不大于45mm/s。
判定产品质量等级，必须符合该等级全部考核项目的分等指标，或按达到的最低一项指标定等级，缺项不能判定产品质量等级。
Compressor products are divided into two grades: qualified product and first-class product, based on their quality level and use value.
In addition to complying with JB/T 6428, the assessment items and indicators for each grade of compressor products shall be in accordance with Table 1.
The volumetric flow rate of the compressor shall not be less than 95% of the rated value.
The vibration severity of the compressor body shall not exceed 45 mm/s.
To determine the product quality grade, all assessment items of that grade must meet the grading indicators, or the grade shall be determined by the lowest indicator achieved; missing items preclude grade determination.
