Household and similar electrical appliances - Safety -- Part 2-72: Particular requirements for automatic machines for floor treatment for commercial and industrial use

This clause of Part 1 is replaced by the following. This International Standard deals with the safety of mains or battery supplied portable combined machines, with or without a built-in battery charger, having a chassis with or without traction drive, intended for commercial and industrial use indoors or outdoors for dry or wet treatment of hard floors or of floors with carpeting, their rated voltage being not more than 250 V for single-phase appliances and 480 V for other appliances. NOTE 101 Examples of such appliances are catering equipment, cleaning appliances for industrial and commercial use, and appliances for hairdressers. NOTE 102 Mobile equipment is defined as portable by part 1. NOTE 103 Treatment within the meaning of this standard denotes for example - scrubbing; - wet or dry pick-up; - polishing; - application of wax and sealing products; - shampooing. It is also applicable to appliances making use of other forms of energy for the motor; but it is necessary that their influence is taken into consideration. For machines denoted to handle hazardous dust in normal use, additional requirements are specified in Annex AA of IEC 60335-2-69.

Introduction
It has been assumed in the drafting of this European Standard that the execution of its provisions is
entrusted to appropriately qualified and experienced persons.
This standard recognizes the internationally accepted level of protection against hazards such as
electrical, mechanical, thermal, fire and radiation of appliances when operated as in normal use taking
into account the manufacturer's instructions. It also covers abnormal situations that can be expected in
practice and takes into account the way in which electromagnetic phenomena can affect the safe
operation of machines.
This standard takes into account the requirements of IEC 60364 as far as possible so that there is
compatibility with the wiring rules when the machine is connected to the supply mains. However, national
wiring rules may differ.
If a machine within the scope of this standard also incorporates functions that are covered by another
Part 2 of EN 60335, the relevant Part 2 is applied to each function separately, as far as is reasonable. If
applicable, the influence of one function on the other is taken into account.
This standard is a product family standard dealing with the safety of machines and takes precedence over
horizontal and generic standards covering the same subject.
A machine that complies with the text of this standard will not necessarily be considered to comply with
the safety principles of the standard if, when examined and tested, it is found to have other features that
impair the level of safety covered by these requirements.
A machine employing materials or having forms of construction differing from those detailed in the
requirements of this standard may be examined and tested according to the intent of the requirements
and, if found to be substantially equivalent, may be considered to comply with the standard.

Part 2-72: Particular requirements for automatic machines
for floor treatment for commercial use

1 Scope
This clause of Part 1 is replaced by the following.
This European Standard deals with the safety of powered ride-on and walk-behind machines intended
for commercial indoor or outdoor use for the following applications:
– sweeping,
– scrubbing,
– wet or dry pick-up,
– polishing,
– application of wax, sealing products and powder based detergents,
– shampooing
of floors with an artificial surface.
Their cleaning motion is more linear than lateral or periodic.
NOTE Z101 By contrast, the cleaning motion of machines covered by EN 60335-2-67 is more lateral or periodic than linear.
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 Part 2 applies in conjunction with EN 60335-1:2002 and its amendments, which is referred to in this
text as “Part 1”. This Part 2 supplements or modifies the corresponding clauses of Part 1 as indicated in
the text.
This standard does not apply to
– machines designed to be part of a production process;
– machines designed for use in corrosive or explosive environments (dust, vapour or gas);
– machines designed for use on slopes with a gradient exceeding 20 %;
– machines equipped with a power take-off (PTO);
– machines designed for picking up hazardous dusts as defined in EN 60335-2-69, inflammable
substances, or aflame particles;
– floor treatment machines for commercial use as covered by EN 60335-2-67;
– spray extraction appliances;
NOTE Z102 EN 60335-2-68 covers spray extraction appliances for commercial use.
– wet and dry vacuum cleaners;
NOTE Z103 EN 60335-2-69 covers wet and dry vacuum cleaners for commercial use.
– road sweepers;

NOTE Z106 Attention is drawn to the fact that
– in many countries additional requirements on the safe use of the equipment covered may be specified by the national health
authorities, the national authorities responsible for the protection of labour, the national water supply authorities and similar
authorities;
– ride-on machines designed for transport over public roads may be subject to additional requirements (e.g. lighting, number

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
Power 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.Z103:
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

PVC-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 shall not be taken as
normal operation but shall be averaged by extending measurements over a period of at least 10 min.
3.1.9.104 Carpet shampooers are operated on a test surface consisting of a carpet, in accordance with
EN 60312, 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.
3.1.9.Z101 Liquid containers of machines for wet scrubbing and shampooing are filled to the highest
level indicated by the manufacturer.
3.1.9.Z102 Additional weights delivered with the machine are fitted before operation.
