1 Scope
This clause of Part 1 is replaced by the following.
This document deals with the safety of powered ride-on and powered walk-behind machines.
This document applies to powered ride-on and powered walk-behind machines intended for commercial indoor or outdoor use for the following applications:
of floors with an artificial surface:
——sweeping,
——scrubbing,
——wet or dry pick-up,
——polishing,
——application of wax, sealing products and powder based detergents,
——shampooing
Their cleaning motion is more linear than lateral or periodic.
Note 101: By contrast, the cleaning motion of machines covered by GB/T 4706.86 is more lateral or periodic than linear.
Note 102: This standard applies to machines for commercial use. The following list, although not comprehensive, gives an indication of locations that are included in the scope:
——public use areas such as hotels, schools, hospitals;
——industrial locations, for example factories and manufacturing shops;
——retail outlets, for example shops and supermarkets;
——business premises, for example offices and banks;
——all uses other than normal housekeeping purposes.
They may be equipped with a traction drive system. The following power systems are covered:
——internal combustion engines,
——mains powered motors up to a rated voltage of 250 V for single-phase appliances and 480 V for other appliances,
——battery powered motors.
Battery powered machines may be equipped with a built-in battery charger.
This standard does not apply to
——floor treatment appliances for household use (IEC 60335-2-10);
——floor treatment machines for commercial use (IEC 60335-2-67);
——spray extraction machines for commercial use (IEC 60335-2-68);
——wet and dry vacuum cleaners, including power brush, for commercial use (IEC 60335-2-69);
——road sweepers;
Note 103: In Europe, EN 13019 covers road sweepers.
——machines designed for use on slopes with a gradient exceeding 20 %;
——machines equipped with a power take-off (PTO);
——machines designed for use in corrosive or explosive environments (dust, vapour or gas);
——machines designed for picking up hazardous dusts (as defined in GB/T 4706.93), inflammable substances, or glowing particles;
——machines designed for use in vehicles or on board of ships or aircraft.
Note 104: Attention is drawn to the fact that
——in many countries additional requirements on the safe use of the equipment covered can be specified by the relevant national authorities.
——ride-on machines designed for transport over public roads can be subject to additional requirements (e.g. lighting, license plate etc.).
Note 105: Requirements for fuel-cells are under consideration.

3 Terms and definitions
This clause of Part 1 is applicable except as follows.
3.1.9 Replacement:
normal operation
conditions under which the machine is operated in normal use, as intended by the manufacturer
It denotes the load corresponding to the rated power input or the highest obtainable load of all particular loads of the various functions that can be operated at the same time in accordance with the manufacturer’s instructions. For machines provided with a seat or an operator platform, a mass of 75 kg secured in position at the appropriate height is used to simulate the operator in the most unfavourable position. Internal combustion engine driven machines are operated with the fuel specified by the manufacturer except where otherwise stated in this standard.
Socket-outlets for accessories are loaded with a resistive load in accordance with the marking.
Operational functions include all treatment and driving functions.
The normal operation related to the operational functions is specified in 3.1.9.101 to 3.1.9.103:
3.1.9.101
Scrubbing and sweeping machines are operated on a surface of hydraulically pressed concrete paving slabs (see Annex AA) intermittently at least 30 min switched on, and for a period of 5 min switched off.
An alternative is a smooth concrete area of a surface consistency comparable with hydraulically pressed concrete paving slabs.
3.1.9.102
Polishing and dry buffing machines are operated as follows.
PVC- or comparable flooring surfaces are considered to be suitable for establishing normal operation. The peak of input occurring during the drying process of the chemical applied to treat the surface is not taken as normal operation but is averaged by extending
measurements over a period of at least 10 min.
3.1.9.103
Carpet shampooers are operated on a test surface consisting of a carpet, in accordance with IEC 60312-1, the carpet being fastened to the floor.
Prior to testing, the brush of the shampooing machine is conditioned by operating it for 15 min on a clean, dry concrete surface. After running on the concrete surface, the brush is immersed in a shampoo solution for at least 30 min.
The solution tank is filled and the machine is operated over a period of 10 min.
3.101
traction drive
system used to propel the machine, e.g. by powered wheels
Traction by the effect of rotating brushes is not included.
3.102
walk-behind machine
machine with or without a traction drive designed to be controlled by the operator walking behind the machine
It may be equipped with a detachable sulky.
3.103
ride-on machine
machine with a traction drive and with an operator seat or a platform on which the operator is sitting/standing during operation
3.104
sulky
trailer
removable trailing seat or stand-on platform with wheels or skids designed to carry an operator in a sitting or standing position, while controlling a walk-behind machine with traction drive
