This standard JB/T 51210－1999 specifies the product quality grading requirements for box-type chain plate tea drying machines, including three grades: qualified, first-class, and premium. It covers specific indicators and test methods for overall performance (e.g., productivity, drying intensity, heat consumption), reliability (availability and mean time to first failure), assembly quality, paint and appearance quality. The inspection rules adopt the sampling plan of GB/T 2828 and make judgments based on nonconformity classification. This standard replaces the previous version and adjusts some technical indicators, applicable to the quality grading of flat tea drying machines.
