B-D试验是专门用于预真空压力蒸汽灭菌器冷空气排除效果的检测试验,根据指示图颜色改变均匀与否来判断灭菌器在灭菌过程中是否有残留的冷空气聚集点,以评估真空灭菌器内排除残余空气及蒸汽渗透情况,其结果会受到灭菌器设备故障、蒸汽质量、试纸质量等因素的影响。 BD test is designed for pre-vacuum pressure steam sterilizer cold air removal test test, according to the indicator color change is uniform or not to determine the sterilizer in the sterilization process there is a residual cold air gathering point to assess Vacuum sterilizers to exclude residual air and steam infiltration, the results will be sterilizer equipment failure, steam quality, test paper quality and other factors.
