摘　　要：基于机械采样装置偏倚性能试验过程中参比样的采样易受人为因素的影响,结合GB/T19494提出一种新的偏倚试验方法,介绍了新偏倚试验方法中的初级采样器功能判定、制样系统偏倚性能鉴定等程序,并探讨了机械采样装置偏倚性能的规范试验过程。Because that sampling of reference sample was easy to be affected by human factors in bias performance test process of mechanical sampling device,and combining with the new bias test method mentioned in GB/T 19494,the processes in new bias test method like function judge of primary sampling machine and bias performance test of sampling system were introduced,the standard experimental process of bias performance test of mechanical sampling device was discussed as well.
