Earth-moving machinery - Falling-object protective structures - Laboratory tests and performance requirements (ISO 3449:2005); English version of DIN EN ISO 3449:2009-07
This International Standard specifies laboratory tests for measuring the structural characteristics of, and gives
performance requirements in a representative test for, falling-object protective structures (FOPS) intended for
use on ride-on earth-moving machines as defined in ISO 6165. It is applicable to both FOPS supplied as an
integral part of the machine and those supplied separately for attachment to the machine. It is not intended to
apply to FOPS intended for use on landfill compactors, excavators, rollers, trenchers, pipelayers, for the
additional seat for operation of an attachment (e.g. attachment backhoe), or on machines with a power rating
of less than 15 kW.
NOTE This International Standard can be used to provide guidance to the manufacturers of roll-over or falling-object
protective structures should it be decided to provide such protection for these or other machines for a particular application.
