吸尘器在极端工作电压的严酷条件下的测试(doc 6页)

吸尘器在极端工作电压的严酷条件下的测试内容提要：
1.0   Purpose / 目的
To evaluate the integrity of polymeric enclosure parts of sample when operated under extreme operating voltages
评估样机在极端工作电压（高和低）下进行的正常负载运行时,其马达塑料零件的安全性.
2.0   Definition/概念: 
2.1   Thermal equilibrium-A state in which three successive temperature readings, taken at intervals of 10% of the previously elapsed duration of the test, but not less than 5 minutes, demonstrate a variation of less than 1℃. 
      热平衡-每隔前面已用的测试时间的10%的间距(但时间不少于5分钟)连续三次读数,其变化少于1℃时样机所达到热平衡状态
2.2   Extreme operating voltages-High and low, for this the high is 127V and low 104V
      极端电压-本测试最高电压为127V,最低电压为104V.
