BS EN 60335-2-72:2009 Household and similar electrical appliances. Safety. Particular requirements for automatic machines for floor treatment for commercial use
BS EN 60335-2-72 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.
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:
– 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.
