This standard JB/T 53118-1999 replaces JB/T 53118-94 and specifies the product quality grading requirements for rubber and plastics pressurized kneaders. Products are classified into three grades: qualified, first-class, and superior. Assessment items include noise value during no-load operation, ratio of main motor power to rated power, mixing chamber rotation angle, and electrical control method. Test methods reference GB/T 12784, sampling requires at least 2 units from inspected products, and grading is based on the lowest index achieved. This standard is for internal use and aims to unify the quality evaluation system.
