This standard specifies the product quality grades, test methods, sampling and evaluation methods for kneaders.
Kneader products are divided into three grades: qualified product, first-class 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 delivered but unopened by the user; 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.
