蒸汽拖把的水箱装满水，再将水箱水分批次倒入一个带刻度的量杯中，计算水箱的总容水量(水箱容积)。将实测水箱容积与水箱标称容积进行比对。
6.9 寿命
用试验用水，保证水箱一直有水的情况下，蒸汽拖把以额定电压供电，调到最大挡位，开30 min同时模拟正常行走(行走速度为0.2 m/s)、关15 min，累计工作150 h，测试完后检查蒸汽拖把是否能正常开机工作，是否有电气不良现象发生。
6.10 除菌性能
遵照附录C的规定进行。
6.11 除螨性能
遵照附录D的规定进行。
6.12 除过敏原性能
遵照附录E的规定进行。
7 检验规则
7.1 检验分类
分为出厂检验和型式检验。
7.2 出厂检验
7.2.1 产品应经本公司检验部门检验合格，并附上合格证书后方可出厂。
7.2.2 出厂检验项目：5.2中的“接地电阻和电气强度”、5.3.1～5.3.3和8.2。
7.2.3 判定规则：若“接地电阻和电气强度"项目和8.2不合格，即直接判出厂检验不合格；其余项目不合格则加倍复检，若再出现不合格，则判出厂检验不合格。
7.3 型式检验
7.3.1 型式检验在下列情况之一时进行：
a) 新产品生产的试制鉴定；
b) 正式生产后，如设计、材料、工艺、设备、结构等有较大改变可能影响产品性能时；
c) 正常生产时，每年至少1次；
d) 产品停产半年以上再恢复生产时；
e) 出厂检验结果与上次检验结果有较大差异时；
f) 质量监督部门或客户提出要求时。
7.3.2 抽样：型式检验的样品在出厂检验合格的产品中随机抽取，数量为3台。
7.3.3 型式检验项目：第5章全部内容和8.2。详见表3规定。
