This International Standard defines test procedures and acceptance criteria for the roll-over protective structures (ROPS) of powered ride-on turf care machinery with a mass of 3 000 kg or less. It is not applicable to stand-on or sulky type machines, nor to self-propelled machinery and tractors used in agriculture, forestry or construction applications. NOTE Product-specific standards such as ISO 5395 specify whether or not a certain type of machine is to be fitted with a ROPS and these can include additional information on aspects related to ROPS, e.g. seat-belt anchorages and seat belts.
