4 The first simulates falls which a specimen, normally in the unpacked state,could undergo during handling and is normally restricted to two falls from a prescribed attitude onto a specifiedsurface from a specified second procedure simulates repeated falls which may occur to such devices as connectors or small remotecontrol units which are normally attached to cables during use. Repeated falls onto a specified surface from aspecified height are achieved by using a suitable apparatus, a tumbling (rotating) 1 Free fall1. ScopeTo assess the effects on a specimen of simple STANDARD tests intended to be representative of the fall likely to beexperienced during rough handling, or to demonstrate a minimum degree of robustness, for the purpose of assessingsafety test is primarily intended for specimens not in their packing and for items in their transport case when thelatter may be considered as part of the specimen itself.
