I. Usage:

a)The tumble barrel drop tester is a special equipment for repeating free drop test on mobile phones (or other small electronic products).

b)This equipment is mainly manufactured according to IEC standard GB/T2423.8-1995.

c) The structure is reasonable, unique, and fully applicable to different types of mobile phones.

d)The tumble barrel drop tester is stable in operation, low noise and maintenance-free.

II, the standard basis: GB/T2423.8-1995 or IEC60068-2-31 test conditions; drum production process to meet the GB/T2423.8-1995 appendix standards.

III, the purpose of the test:

A. Durability of the shell.

B. Performance of internal structure against (heavy) fall.

C. Adaptability to withstand repeated free fall.

IV. Description of the test process

simulate the user's use of the process, the mobile phone free fall action for the test.

manually put the mobile phone into the drum → close the transparent cover and protection device → the motor drives the drum to rotate counterclockwise → rotate one week to fall twice.

V. Function :

1, by the motor to achieve a fixed number of drum rotation (5 rpm);

2, the drum falling height of 1000mm;

3, the drum structure to ensure that mobile phones fall randomly, to avoid non-standard friction and collision movement.

VI. Technical indicators：
