This standard JB/T 53116-1999 specifies quality grading requirements for plastics mixers, including three grades: qualified, first-grade, and premium. It covers performance parameters for hot and cold mixers (e.g., output, mixing quality, noise, mixing time) and assembly accuracy (radial runout of the main shaft). Test methods reference JB/T 7669, sampling requires at least 2 units, and grading is based on the lowest indicator. The standard provides a basis for quality control and user selection of plastics mixers.
本标准JB/T 53116-1999规定了塑料混合机产品的质量分等要求，包括合格品、一等品和优等品三个等级。标准覆盖了热机和冷机的性能参数（如产量、混合质量、噪声、混合时间）以及装配精度（主轴径向圆跳动）。试验方法引用JB/T 7669，抽样要求至少2台，评定按最低指标定级。该标准为塑料混合机的质量控制和用户选型提供了依据。

本标准规定了塑料混合机产品的质量等级、试验方法和抽样与评定方法。
塑料混合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。
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，全部检测项目采用一次检测。
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。
塑料混合机产品除符合JB/T 7669规定外，各等级的考核项目、指标要求还应分别符合表1~表4的规定。
This standard specifies the quality grades, test methods, and sampling and evaluation methods for plastics mixer products.
Plastics mixer products are divided into three grades: qualified product, first-grade product, and premium product, based on their quality level and use value.
Sampled products must be batch products that have passed inspection by the manufacturer's inspection department and are in storage or unopened at the user's site; the sample size shall be no less than 2 units, and all test items shall be tested once.
When evaluating the product quality grade, it must meet the technical requirements of all assessment items for that grade; otherwise, the grade shall be determined by the lowest indicator achieved.
In addition to complying with JB/T 7669, the assessment items and indicator requirements for each grade of plastics mixer products shall also meet the provisions of Tables 1 to 4, respectively.
