14.2 Replacement:The enclosure of the machine shall provide the degree of protection against moisture in accordance with the marking of the machine.Compliance is checked by the appropriate treatment specified in 14.2.2, with the machine conditions as in 14.2.1.14.2.1 Replacement:The machine is not connected to the supply.Detachable parts which can be removed without the aid of a tool are removed and subjected, if necessary, to the relevant treatment with the main part. Machines fitted with an appliance inlet, plug or other connector are tested without the mating connector in place. Air filters are not removed.14.2.2 Replacement:Machines other than IPX0 are subjected to tests of IEC 60529:2013 as follows:– IPX1 machines are subjected to the test described in 14.2.1;– IPX2 machines are subjected to the test described in 14.2.2;– IPX3 machines are subjected to the test described in 14.2.3a;– IPX5 machines are subjected to the test described in 14.2.5. For this test, the water stream is applied from all practicable directions, including the underside of the machine; – 18 – IEC 62841-4-3:2020 © IEC 2020– IPX6 machines are subjected to the test described in 14.2.6. For this test, the water stream is applied from all practicable directions, including the underside of the machine;– IPX7 machines are subjected to the test described in 14.2.7. For this last test, the machine is immersed in water containing approximately 1,0 % NaCl.Machines classified as IPX4 are subjected to the test described in 14.2.4a of IEC 60529:2013, except as follows:– the test is conducted with a circular horizontal unperforated support having a diameter of twice the oscillating tube radius minus 15 cm. The support is placed at the level of the pivot axis of the oscillating tube. During the test, the support is rotated about its vertical axis at a rate of (1 ± 0,1)/min;– the machine is placed on the unperforated support; and– the cutting height is set to 30 mm or the next higher cutting position when set on a hard level surface. Machines with a maximum cutting height setting of 30 mm or less are set at their maximum cutting height setting; and– the horizontal centreline of the machine is aligned with the pivot axis of the oscillating tube at the start of test. The movement of the oscillating tube is limited to 90° either side from the vertical, the time for one complete oscillation (2 × 90°) being (6 ± 1) s;– the duration of the test is 10 min.Immediately after the appropriate treatment, the machine shall withstand the electric strength test of Annex D between live parts and accessible parts, the test voltage being 2 500 V. The function of any SCF shall not be impaired.14.3 to 14.5 These subclauses of Part 1 are not applicable.<br>
