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 machines 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.

normal operation conditions under which the machine is operated in normal use, obtained at the following power input Pm of the vacuum motor: Pm = 0,5 (Pf + Pi) where Pf is the input, in watts, when the machine has been operated for 3 min, fitted with the nozzle and hose giving the highest input; SIST EN 60335-2-69:2009

– 9 – EN 60335-2-69:2009 Pi is the input, in watts, when the machine has been operated for 20 s with the nozzle sealed, immediately following the 3-minute-period with the nozzle open. Any valve or similar device used to ensure a flow of air to cool the motor in the event of a blockage of a main air inlet is rendered ineffective. Pf and Pi are measured with the supply voltage adjusted to rated voltage, or to a voltage equal to the mean value of the rated voltage range if the difference between the limits of the rated voltage range does not exceed 10 % of the mean value of the range. If the difference between the limits of the rated voltage range exceeds 10 % of the mean value, the tests are carried out with the supply voltage set to the upper limit of the range. The measurements are made with the machine fitted with a clean dust bag and filter and with the water container, if any, empty. If the machine is intended for use only with a hose, detachable nozzles are removed and the hose is laid out straight. If the machine is provided with a hose as an optional accessory, it is operated without the hose. Electrically driven devices, if any, are in operation but are not in contact with the floor or any other surface or with the means used to seal the air inlet. The normal load is equal to the mean load Pr for the electrically driven agitating device such as a motor driven brush determined in accordance with the following: – the agitating device operates on a carpet as specified in IEC 60312; – the mean load Pr is determined when using the device in the following way:
After setting the device, the device shall be moved twice over a distance of 5 m in the direction giving the highest load; –
the motor responsible for the airflow operates under the same conditions as determining Pf , i.e. no airflow restrictions, and measurements are taken after 3 min; – the device is adjusted to the carpet pile height; – it is necessary to move the agitating device slowly across the carpet to avoid carpet damage. Soiled water discharge pumps, if applicable, are operated as follows.
The pump delivers a continuous flow of water without any soiled water discharge hose attached to the soiled water outlet of the machines unless the discharge hose is permanently attached to the machine. The vacuum motor shall work during the test, unless an interlock device is provided to prevent combined operation of both motors. 3.Z101 water-suction cleaning machine machine for sucking up a water-based cleaning solution 3.Z102 back-pack vacuum cleaner vacuum cleaner designed to have the power source and collector carried on the operator’s back by means of a supporting device 3.Z103 motorized cleaning head hand-held or hand-guided cleaning device connected to the machine, with an integrated electrical motor NOTE The permanently attached main cleaning head is not regarded as a motorized cleaning head.

Other machines are tested as delivered. The liquid container of the machine is completely filled with a saline solution of water containing approximately 1 % NaCl and a further quantity, equal to 15 % of the capacity of the container or 0,25 l, whichever is the greater, is poured in steadily over a period of 1 min. Machines which are unstable are then, with the container completely filled and with the cover or lid in place, overturned from the most unfavourable of the normal positions of use, and are left in that position for 5 min unless the machine returns automatically to its normal position of use. Nozzles and motorized cleaning heads of water-suction cleaning machines are placed in a tray, the base of which is level with the surface supporting the machine. The tray is filled with the test solution to a level of 5 mm above its base, this level being maintained throughout the test. The machine including the motorized cleaning head is operated until its liquid container is completely full and afterwards for a further 5 min. After each of these tests, the machine shall withstand the electric strength test of 16.3. There shall be no trace of liquid on insulation that reduces the clearances or creepage distances below the values specified in Clause 29. 15.3 Modification:
The relative humidity shall be (93 ± 6) %. 15.101 The insulation of motorized cleaning heads of water suction cleaning machines shall be resistant to the mechanical impact of picked up debris and sucked up liquids expected under normal use. The following test is not applicable to motorized cleaning heads of class III construction having a working voltage up to 24 V. Compliance is checked by the following four tests. The motorized cleaning head is subjected to an impact test as described in IEC 60068-2-75, the value of the impact being 2 J. The motorized cleaning head is rigidly supported and three blows are applied to every point of the enclosure that is likely to be weak.
– 17 – EN 60335-2-69:2009 It is then subjected to the free fall test procedure 1 of IEC 60068-2-32. It is dropped 4 000 times from a height of 100 mm onto a steel plate having a thickness of not less than 15 mm. It is dropped – 1 000 times on its right side; – 1 000 times on its left side; – 1 000 times on its front face; – 1 000 times on its cleaning surface. The motorized cleaning head is then subjected to the test described in 14.2.7 of IEC 60529, using the test solution. The motorized cleaning head shall then withstand the electric strength test of 16.3, the voltage being applied between the live parts and the test solution. There shall be no trace of saline solution on insulation that reduces the clearances and creepage distances below the values specified in Clause 29. 16 Leakage current and electric strength This clause of Part 1 is applicable except as follows. 16.3 Addition: Current-carrying hoses, except for their electrical connections, are immersed for 1 h in a saline solution of water containing approximately 1 % NaCl, at a temperature of 20 °C ± 5 °C. While the hose is still immersed, a voltage of 2 000 V is applied for 5 min between each conductor and all the other conductors connected together. A voltage of 3 000 V is then applied for 1 min between all the conductors and the saline solution. 17 Overload protection of transformers and associated circuits This clause of Part 1 is applicable. 18 Endurance This clause of Part 1 is not applicable. 19 Abnormal operation This clause of Part 1 is applicable except as follows. 19.1 Addition: Machines are also subjected to the test of 19.101. The test of 19.7 is only applicable to motorized cleaning heads. 19.2 Addition: The machine is tested without liquid in the container. NOTE 101 The term restricted heat dissipation of Part 1 means without liquid in the container. SIST EN 60335-2-69:2009

19.7 Addition: Motorized cleaning heads are tested with the rotating brush or similar device locked for 30 s. 19.9 Not applicable. 19.10 Addition: For this test the lowest possible load for radial turbines is obtained with the air inlet sealed. For other types of turbines the characteristics shall be taken into account. In the case of cleaners driving a brush or agitator, the belt is removed. 19.13 In the second paragraph add “and 22.Z102” after “20.2”. 19.101 Machines having containers that are provided with shut-off device(s) or valve(s) are again subjected to the test of 15.2. Stop valves or other fluid shut-off devices are made inoperative. If two or more independent shut-off devices are provided, only one of them is made inoperative at a time, provided that they have passed the test of operating 3 000 times satisfactorily. Otherwise all devices that failed are made inoperative. NOTE Care should be taken to suck up an air-liquid mixture to prevent overloading of the motor of the suction unit. The input power should be observed to avoid overloading. After this test, the machine shall be subjected to the electrical strength test of 16.4. Inspection shall show that water has not entered the machine to any dangerous extent. In particular, there shall be no trace of water on the electrical insulation that reduces the clearance and creepage distances below the limits specified in Clause 29. 20 Stability and mechanical hazards This clause of Part 1 is applicable except as follows. 20.1 Addition: Motorized cleaning heads are not subjected to this test. 20.2 Addition: These requirements do not apply to rotating brushes and similar devices, or to moving parts exposed during the fitting of accessories that allow conversion from one a
