IEC 60335-2-2-2019 pdf download.Household and similar electrical appliances — Safety — Part 2-2: Particular requirements for vacuum cleaners and water-suction cleaning appliances
Appareils électrodomestiques et analogues — Sécurité — Partie 2-2: Exigences particulières pour les aspirateurs et les appareils de nettoyage a aspiration d’eau.
The temperatures of the windings shall not exceed the values specified in Table 8.
19.10 Replacement:
Appliances incorporating series motors are supplied at 1,3 times rated voltage and operated for 30 s with the air inlet blocked, rotating brushes and similar devices being removed.
After this test, the safety of the appliance shall not have been impaired, in particular windings and connections shall not have worked loose.
19.101 Water-suction cleaning appliances, the liquid container of which incorporates a valve or other overfill prevention device, are supplied at rated voltage. The appliance is operated with the nozzle placed in a trough containing water and with the valve or overfill prevention-device held open or otherwise rendered inoperative. The test is terminated 30 S after water starts to flow out of the appliance.
If the appliance incorporates more than one overfill prevention device, these are rendered inoperative in turn.
19.102 The deactivating means of the booster setting is rendered inoperative and the appliance is operated under the conditions specified in Clause 11 using the booster setting.
19.103 Centrally-sited vacuum cleaners are supplied at rated voltage and operated with the inlet for the suction hose open and then closed.
The temperatures of the windings shall not exceed the values specified in 19.9.
19.104 Centrally-sited vacuum cleaners with separate ventilation for the motor are supplied at rated voltage and operated with the airflow through the motor blocked.
19.105 Ash vacuum cleaners shall not cause a risk of fire or electric shock when operated under the following test conditions:
The ash vacuum cleaner is prepared for operation according the instruction for use, but switched off
The empty container of the ash vacuum cleaner is filled up to two-thirds of its useable volume with paper balls. Each paper ball is made out of crumpled sheets of A4 copy paper having a weight in the range 70 g/m2 to 120 g/m2 in accordance with ISO 216. Each paper sheet shall be crumpled to a size so that it fits into a cube having sides of 10 cm.
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:
The requirement regarding moving parts does not apply to rotating brushes and similar devices. It does not apply to parts that become accessible when changing accessories and only move when the brush or similar device is in operation.
21 Mechanical strength
This clause of Part I is applicable except as follows.
21.101 Current-carrying hoses shall be resistant to crushing.
Compliance is checked by the following test.
The hose is placed between two parallel steel plates each having a length of 100 mm. a width of 50 mm and the edges of the longer sides rounded with a radius of 1 mm. The axis of the hose is positioned at right angles to the longer sides of the plates. The plates are placed at a distance of approximately 350 mm from one end of the hose.
The steel plates are pressed together at a rate of 50 mm/mm ± 5 mm/mm until the applied force is 1.5 kN. The force is then released and the electric strength test 0(16.3 is carried out between the conductors connected together and the saline solution.
21.102 Current-carrying hoses shall be resistant to abrasion. Compliance is checked by the following test.
One end of the hose is attached to the connecting rod of the crank mechanism shown in Figure 101. The crank rotates at 30 rlmin resulting in the end of the hose moving horizontally backwards and forwards over a distance of 300 mm.
The hose is supported by a rotating smooth roller over which a belt of abrasive cloth moves at
a speed of 0,1 rn/mm. The abrasive is corundum grit size P100. as specified in Iso 6344-2.
A mass of 1 kg is suspended from the other end of the hose, which is guided to avoid rotation.IEC 60335-2-2-2019 pdf download.
