JIS C 0056:2001

This Standard details methods for testing components, equipments and other electrotechnical products which in service can be subjected to pulsating or oscillating forces of short duration caused, for example, by seismic or explosive phenomena or by vibration in machinery. In this test the specimen is excited at fixed frequencies with a preset number of sine beats (see attached figure 1). These fixed test frequencies are predetermined frequencies, critical frequencies identified by means of a sinusoidal vibration test (IEC 60068-2-6) or both. Pauses are provided between the individual sine beats in order to allow decay of the free response of the specimen. Specification writers will find in clause 12 a list of details to be considered for inclusion in specification and, in annex A, the guidance.
