3.1.9 Electrically driven devices, if any, are in operation but are not in contact with the floor or any other surface or with the means used to seal the air inlet.

The normal load is equal to the mean load Pr for the electrically driven agitating device such as a motor driven brush determined in accordance with the following:
– the agitating device operates on a carpet as specified in IEC 60312;
– the mean load Pr is determined when using the device in the following way:
  j7 A" C) f% F5 E& ]9 ~& D0 F% R, Z. ~After setting the device, the device shall be moved twice over a distance of 5 m in the direction giving the highest load;
– the motor responsible for the airflow operates under the same conditions as determining Pf , i.e. no airflow restrictions, and measurements are taken after 3 min;
– the device is adjusted to the carpet pile height;
3 m& H' z3 i; |* v2 ^( T– it is necessary to move the agitating device slowly across the carpet to avoid carpet damage.
请教各位大侠一个问题：我有一款吸尘器，只有一个马达用于吸尘同时还通过一个皮带带动一个小刷子擦地面灰尘。按标准应该是属于Electrically driven devices同时也是electrically driven agitating device such as a motor driven。是吧？
/ ~! H/ G* ^7 Z- k( V9 x0 l& S那么这样的话我测试的时候是刷子擦地面呢还是不擦呢？

要做的，根据11.5模拟来测试
$ e) z1 Z0 u+ M* e& @( o
11.5 For the heating test the normal load Pr on the motor driving the moving brushes can be simulated by a brake or other means.

but how to realize by a brake or ther means? It is difficult to understand.

这是要分为两部分理解，是两种使用状态的测试要求：
第一： Electrically driven devices, if any, are in operation but are not in contact with the floor or any other surface or with the means used to seal the air inlet.
% U2 U) I! j7 G+ y6 G为(Mean Watt)平均功率，开、堵进气口而求出平均功率，但不能影响毛刷的正常运行；

第二：The normal load is equal to the mean load Pr for the electrically driven agitating device such as a motor driven brush determined in accordance with the following:
9 |: q3 Z# X3 C2 W2 ?/ V– the agitating device operates on a carpet as specified in IEC 60312;
4 F  X4 E' E$ n* u) b. y! v1 t– the mean load Pr is determined when using the device in the following way:
After setting the device, the device shall be moved twice over a distance of 5 m in the direction giving the highest load;
- c4 U+ t1 |- K7 x' t– the motor responsible for the airflow operates under the same conditions as determining Pf , i.e. no airflow restrictions, and measurements are taken after 3 min;
& h0 P& _% @* q* D( X– the device is adjusted to the carpet pile height;
% `1 q6 I8 j' K: M/ E  O– it is necessary to move the agitating device slowly across the carpet to avoid carpet damage.
为在标准地毯上正常运行状态，要将毛刷档位调到最低，即最大负载
