24.3 The bases of surface type socket-outlets are first fixed to a cylinder of rigid steel sheet,
having a radius equal to 4,5 times the distance between fixing holes but, in any case, no less
then 200 mm. The axes of the holes are in a plane perpendicular to the axis of the cylinder
and parallel to the radius through the centre of the distance between the holes.
The fixing screws of the base are gradually tightened, the maximum torque applied being
0,5 Nm for screws having a thread diameter up to and including 3 mm and 1,2 Nm for screws
having a larger thread diameter.
The bases of socket-outlets are then fixed in a similar manner to a flat steel sheet.
During and after the tests, the bases of socket-outlets shall show no damage impairing their
further use.这是原文 讲解的是对于固定式插座底座的安装的要求大概是这个意思但是感觉好像从来没看到过这么做。
求大神讲解 |
