1 GB/T1043—2008 fastener lateral vibrating testing method, DIN65151

Motive power testing of locking capacity for fastener with lateral loading

Testing fastener is clamped with determinate loading, frequency, amplitude, broadwise and dynamic loading for testing of self-locking capacity(anti-loosing capacity).

Recording instantaneous value of clamping loading, analysing and judging anti-loosing capacity of fastener.

2 GJB715.3A—2003 vibrating testing of self-locking nut

It must be no damaging of structure, cracking, disrupting, loosing of fastener, damaging of screw thread, disappearing of locking capacity.

Permitting rotating angle of nut relative to bolt is equal or less than 360°.

If bolt is damaged, nut should not be judged not qualifed.
