3.1 Basic terms and definitions
3.1.1 machine
machinery
assembly, fitted with or intended to be fitted with a drive system consisting of linked parts or components, at least one of which moves, and which are loined together for a specific application
Note I to entry: The terms “machincry and machined also cover an assembly of machines which, in order to
achieve the same end, are arranged and controlled so that they function as an integral whole.
[SOURCE: ISO 12100:2010, 3.1, modified — “and machine” has been added to Note 1; Note 2 has been
omitted.]
3.1.2 agricultural field equipment agricultural vehicle
agricultural tractors (32JJ. self- propelled machines (122). implements (3.2.3 to 3.2.4), interchangeable
towed machinery (3.1,3). trailers (3,2.f), and combinations thereof designed primarily for agricultural field operations and occasional road travel
3.1.3 interchangeable towed machinery
machine which is designed to be towed by an agricultural tractor (321) or self-propelled machine (122) and changes or adds to its functions
Note I to entry: It may include a load platform designed and constructed to receive any tools and appliances needed for those purposes, and to store temporarily any materials produced or needed during work.
Note 2 to entry: Any vehicle intended to he towed by a tractor and
rights reserved
Iso 12934:2021(E)
— designed to process materials, or
— permanently incorporating an implement
shall be considered interchangeable towed machinery if the ratio of the technically permissible mass to the unladen mass of that vehicle is less than 3,0.
3.1.3.1 on-road towed implement
interchangeable towed machine (3L3) that is specifically designed to be additionally towed by a motor vehicle on public roadways and is intended for off-road agricultural use
Note Ito entry: Motor vehicle as defined in ISO 3833:1977, 3.1.
3.1.4 maximum design ground speed
speed based on the nominal design capability of the machine with tyres or endless tracks offered as original equipment
Note 1 to entry: The tyre size will be the largest diameter drive tyres on agricultural tractors (32JJ and self- propelled machines (122) but not necessarily on towed equipment.
Note 2 to entry: In order to account for various unavoidable errors due, in particular, to the measuring technique and to the increase in running speed of the engine with a partial load, a measured speed may exceed the value for the maximum design ground speed by 3 km/h. An additional 5 % tolerance on the measured speed shall be permitted to account for variations due to tyre size.
3.1.5 maximum mass
mass stated by the agricultural vehicle (112) manufacturer to be technically permissible
3.1.6 technically permissible mass
sum of the maximum allowable equipment mass and allowable payload specified by the manufacturer
Note 1 to entry: This mass corresponds to the sum of the technically maximum possible axle loads and, in the case of a semi mounted trailer, the vertical static load.
3.1.7 unladen mass
mass of the agricultural vehicle (112) in running order, if applicable with full fuel, DEF, lubricant and coolant tanks and with a driver of a mass of 75 kg, but without passengers, optional accessories or load
3.1.8 agricultural unoccupied aerial vehicle
unoccupied aerial vehicle used for specific agricultural purposes, such as gathering image-based crop data, field surveying, livestock movement, spraying, other aerial based information gathering
3.1.9 width
distance measured between the vertical planes parallel to the longitudinal axis of the vehicle and passing through the outermost points of the agricultural vehicle (112) in a configuration for public roadway transport, but excluding:
— any mirrors;
— any direction indicators;
— any front, lateral or rear position (side) lamps and any parking lamps;
— any folding components such as lift-up footrests and flexible mud-flaps.ISO 12934 pdf download.
