Test Cylinder meets the standard of IEC 60884-1 Clause 24.3.
Test Procedure and requirements:
The main parts 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 main parts of socket-outlets are then fixed in a similar manner to a flat steel sheet.
During and after the tests, the main parts of socket-outlets shall show no damage impairing their further use.
Test Cylinder Technical parameters：
- Radius：R > 200mm，it is equal to the 4.5 times of the distance between the mounting hole.
- height：more than 200
