UL 60335-2-67-2017 pdf download.Household and Similar Electrical Appliances -Safety – Part 2-67: Particular requirements for floor treatment machines, for commercial use.
15 Moisture resistance
This clause of Part 1 is applicable except as follows,
15.1.2 Addition:
Wet cleaning machines, except shampooing machines. are operated for 10 mm with to and from movements over a distance of I m at 15 cycles per minute on a floor of paving slabs with a smooth surface that are fastened to the bottom of a tray. At the beginning of the test, the fray is tilled with the TEST sow nov to a level of approximately 5 mm above the surface of the floor
15.2 Replacement:
Machines having a liquid container shall be so constructed that
— spillage of liquid due to NoRMAL o€iioi,
— filling including overt illing, and
— overturning of HAP+IEW APPLIANCES and unstable machines
does not affect their electrical insulation.
Compliance is checked by the following tests:
The machine is placed on a support inclined at an angle ottO ‘ to the hon.zontal. the liquid container being filled to half The level indicated in the instructions. A machine is considered to be unstable if It overturns when a force of 180 N is applied to the top of the machine in the most unfavourable hohzont& direction.
Machines having a liquid container and provided with an appliance inlet are fitted with an appropriate connector and flexible cable or cord: machines having a liquid container and rvi’€ x rr*cie.ri.’T are fitted with the lightest cross-sectional area specified in Table 11 of the Part I. Other machines are tested as delivered.
The liquid container of the machine is completely filled with a saline solution of water containing approximately I % NaCI and a further quantity, equal to 15 % of the capacity of the container or 025 l whichever is the greater, is poured in steadily over a period of I mm.
aNo-HELo APPLIA.M2ES and machines that are unstable are then, with the container completely filled and with the cover or lid in place, overturned from the most unlavourable of the normal positions of use, and are left in that position for 5 mm unless the machine returns automatically to its normal position of use.
MOTORiZED CLEAAIIN€3 NEADS Of W4TER-SL’CT ctrso wcims are placed in a tray, the base of which is level with the surface supporting the machine. The tray is filled with the rssr srnov to a level of 5 mm above its base, this level being maintained throughout The test. The machine including the ororo C 1EAO is operated until its liquid container is completely fuN and afterwards lot a further 5 mEn.
After each of these tests, the machine shall withstand the electric strength test of 16.3.
The unintentional closing and lowering of doors, lids, covers etc., which could cause injury, shall be prevented
Machines heavier than 20 kg (empty) shall be equipped with wheels or rollers for transport, which shall be located or protected so as to prevent injury to the feet of the OPERAT0.
Compliance is checked by inspection, by measurement and by functional test.
20.103 Fuel tank
If a fuel tank is within or contiguous to the engine compartment and excessively high temperatures may occur, the tank and/or filling arrangement shall be isolated from the electrical and exhaust systems by suitable protection, e.g. a separate enclosure or baffles.
The tank location and facilities for filling shall be such that spillage or leakage will not drain onto electrical or exhaust system parts.
Fuel spillage shall not be possible under NO’AL CPRATION.
Compliance is checked by inspection.
20.104 Internal combustion engine powered machines using liquefied petroleum gas
Internal combustion engine powered machines using liquefied petroleum gas (LPG) shall be constructed in accordance with the additional requirements specified in Annex BB. Requirements for the LPG conlainer itself are not part of this standard.
Compliance is checked by inspection and measurement.
21 MechanIcal strength
This clause of Part I is applicable except as follows.
21.1 Replacement of the first paragraph by the following text:
Machines and their components and fittings shall have adequate mechanical strength and be constructed to withstand such rough handling that may be expected in normal use, during transportation, assembly, dismantling, scrapping and any other action involving the machine.
Modification:
In the third paragraph, the impact value is increased to 10 J ± 0,04 J.
