本标准规定了鞋用转盘注射成型机产品的质量等级、试验方法和抽样与评定方法。
鞋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。
实测注射质量、注射速率、塑化能力不得小于表中值的95%。
评定产品质量等级，必须符合该等级全部考核项目的技术要求，否则按达到的最低一项指标定等级。
抽样产品必须是制造厂检验部门检查合格入库或出厂在用户处未开箱的批量产品，抽检样本不少于2台，全部检测项目采取一次性检测。
This standard specifies the quality grades, test methods, and sampling and evaluation methods for rotary injection molding machine for shoes products.
Shoe machine products are divided into three grades: qualified product, first-class product, and premium product, based on their quality level and use value.
The measured injection mass, injection rate, and plasticizing capacity shall not be less than 95% of the values in the table.
When evaluating the product quality grade, it must meet the technical requirements of all assessment items for that grade; otherwise, the grade is determined by the lowest indicator achieved.
Sampled products must be batch products that have passed inspection by the manufacturer's inspection department and are in storage or shipped but unopened at the user's site; the sample size shall be no less than 2 units, and all test items shall be tested in a single inspection.
