JB/T 53028-1999 specifies the quality grading of conical twin-screw plastic extruders, classifying products into qualified, first-grade, and superior grades. It defines assessment indicators such as specific power, specific flow rate, output, and noise, with specific values for different small-end diameters of the screw. Test methods reference JB/T 6492, and evaluation requires meeting all items of a grade, otherwise the grade is determined by the lowest indicator. This standard is used by manufacturers for quality control and product classification.

本标准规定了锥形双螺杆塑料挤出机产品的质量等级、试验方法和抽样与评定方法。
挤出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。
挤出机产品除符合JB/T 6492 规定外，各等级的考核项目还应符合表1 的规定。
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。
产品评比时，主要考核合乎质量要求的产量及比流量和实际比功率。
This standard specifies the quality grades, test methods, and sampling and evaluation methods for conical twin-screw plastic extruder products.
Extruder products are divided into three grades: qualified product, first-grade product, and superior product, based on their quality level and use value.
In addition to complying with JB/T 6492, the assessment items for each grade shall also comply with the provisions of Table 1.
When evaluating the product quality grade, all technical requirements of the assessment items for that grade must be met; otherwise, the grade shall be determined by the lowest indicator achieved.
During product evaluation, the main assessments are the output meeting quality requirements, the specific flow rate, and the actual specific power.
