1 Scope

This clause of Part 1 is replaced by the following.

This International Standard deals with the safety of powered ride-on and powered

WALK-BEHIND MACHINES

– 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 101 By contrast, the cleaning motion of machines covered by IEC 60335-2-67 is more lateral or periodic than linear.

NOTE 102 This standard applies to machines for

commercial use

– 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

– internal combustion engines,

– mains powered motors up to a

RATED VOLTAGE

– 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

– spray extraction machines for

COMMERCIAL USE

– wet and dry vacuum cleaners, including power brush, for

COMMERCIAL USE

– road sweepers;

NOTE 103 In Europe, EN 13019 covers road sweepers.

– machines designed for use on

SLOPES

– 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 IEC 60335-2-69), 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 national health authorities, the national authorities responsible for the protection of labour, the national water supply authorities and similar authorities;

–

RIDE-ON MACHINES

NOTE 105 Requirements for fuel-cells are under consideration.

They may be equipped with a

TRACTION DRIVE

1. – mains up to a

   RATED VOLTAGE

   of 250 V for single-phase appliances and 480 V for other appliances,

2. – internal combustion engines;

3. – batteries supplying 150 V or less;

4. – double layer (ultra) capacitors;

5. – fuel cells.

Energy sources or power systems utilizing both

BATTERY

1. – floor treatment appliances for household use according to CAN/CSA-E60335-2-10 / CSA C22.2 No. 243 / UL 1017;

2. – floor treatment machines for

   COMMERCIAL USE

   according to CSA C22.2 No. 60335-2-67 / UL 60335-2-67 / CSA C22.2 No. 10 / UL 561;

3. – spray extraction machines for

   COMMERCIAL USE

   (CSA C22.2 No. 60335-2-68 / UL 60335-2-68 / CSA C22.2 No. 10 / UL 561);

4. – wet and dry vacuum cleaners, including power brush, for

   COMMERCIAL USE

   (CSA C22.2 No. 60335-2-69 / UL 60335-2-69 / CSA C22.2 No. 243 / UL 1017);

5. – machines designed for picking up hazardous dusts (CSA C22.2 No. 60335-2-69 / UL 60335-2-69), inflammable substances, or glowing particles;

Except as noted, powered cleaning machines covered by this standard, other than mains supplied machines, are those identified by NFPA 505 as Types E, EE, ES, CGH, CNS, G, GS, D, DS, LP, LPS, CN, G/LP, GS/LPS, G/CN, and GS/CNS. Machines identified by NFPA 505 as Types EX, DY, and DX are not covered by this standard.

NOTE 106DV Additional requirements applicable to machine designations that include the letters “EE” or “S” can be found in Annexes 101.DVD and 101.DVE.

NOTE 107DV

BATTERY-OPERATED APPLIANCES

BATTERY-OPERATED APPLIANCES

This standard covers the above-noted products that are intended to be installed or used in accordance with:

1. – CSA C22.1, Canadian Electrical Code (CE Code), Part I,

2. – NFPA 70, National Electrical Code (NEC), in the United States.

NOTE 108DV This Part 2-72 may be employed for investigation of components and sub-assemblies for the purpose of their pre-selection for use in appliances. If the component or sub-assembly used complies with this standard, the tests for the component or sub-assembly specified in the particular appliance standard in some cases will not need to be made in the particular appliance or assembly. Additional testing on a component or subassembly may be required. For example, if a control system is associated with the particular appliance control system, additional tests could potentially be necessary on the final appliance.

Summary of Topics

This new edition of ANSI/UL 60335-2-72 is an adoption of IEC 60335-2-72, Household and similar electrical appliances – Safety – Part 2-72: Particular requirements for floor treatment machines with or without traction drive, for commercial use (Edition 4, issued by the IEC May 2016). Please note that the national difference document incorporates all of the U.S. national differences for UL 60335-2-72.
