本标准规定了吸附制氧、制氮设备产品的质量等级、试验方法、抽样和评定方法。
吸附制氧、制氮设备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。
吸附制氧、制氮设备除应符合JB/T 6427 的规定外，各考核项目指标和产品质量指标要求按表1及表2 的规定。
抽样检查的产品应是通过鉴定，具有批量生产条件，并经制造厂自检合格，制造完工后在制造厂内不超过6 个月，在用户处不超过18 个月的产品。
判定产品质量等级，必须符合该等级全部考核项目的质量指标，按最低一项指标定等级，缺项不能判定产品质量等级。
This standard specifies the quality grades, test methods, sampling and evaluation methods for oxygen and nitrogen adsorption equipment products.
Oxygen and nitrogen adsorption equipment 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 6427, the indicators of each assessment item and product quality indicators for oxygen and nitrogen adsorption equipment shall comply with the provisions of Table 1 and Table 2.
The product for sampling inspection shall be a product that has passed appraisal, has batch production conditions, has passed the manufacturer's self-inspection, and is within 6 months after completion at the manufacturer's site or within 18 months at the user's site.
To determine the product quality grade, the quality indicators of all assessment items for that grade must be met; the grade is determined by the lowest indicator, and the product quality grade cannot be determined if items are missing.
