20 Stability and mechanical hazards
Delete, on pages 25 and 27, the text of 20.2 and replace it with the following:
20.2 Add the following after the second requirement paragraph:
Covers and the like, protecting danger zones within the operating range of the appliance shall
be detachable only when the risk is excluded by other means.
NOTE 101 Parts which do not move more than 4 mm away from each other are not regarded as dangerous
crushing (squashing) and shearing zones.
NOTE 102 Drawing-in zones can only occur during operations where uncovered movable parts move past
stationary and/or moving parts.
Add the following after the first test specification paragraph:

However, for feed apertures and discharge apertures, unless otherwise specified, the test is
carried out with a test finger similar to that shown in figure 1 but having a non-circular stop
face with a diameter of 56 mm instead of 50 mm and with the distance between the tip of the
test finger and the stop face being 120 mm. The 75 mm diameter guard is removed. The test
finger is not inserted into the aperture for a linear distance of more than 850 mm, measured
from the tip of the finger, if the aperture has a largest dimension of less than 150 mm.
NOTE 103 Moving parts which can be touched by the test finger through discharge apertures are not considered
to be dangerous if they have a smooth surface or are constructed so that the risk of entrapment or injury is
negligible.
60335-2-64 amend. 1 © IEC:2000(E) – 5 –

For some appliances, complete protection is impracticable and the test with the test finger is
therefore not carried out. Examples of such appliances are

– hand-held appliances
–slicers
– tin openers
– pastry rollers
– noodle strip cutters
– sieving machines
– peelers (discharge apertures only)
– bone saws (circular or band type)
– citrus juice squeezers
– egg beaters designated as attachable accessories
– knife sharpeners
Delete note 1 and renumber note 2 as note 1.

20.103 Replace this subclause with the following:
20.103 Appliances, or parts of appliances, which are designed to tilt in normal use shall not
give rise to any hazard. Accidental tilting from any position, even in the case of supply
interruption, shall be prevented, and there shall be no crushing zone between the tilting part
and the appliance except at the bumper point when the part is fully tilted.
Compliance is checked by inspection, by manual test and by switching off the supply to the
appliance at any time during the tilting operation.
NOTE The requirement may be met by, for example, one of the following means:
– providing switches which have to be kept switched on by hand;
– limiting the rate of motion (peripheral speed) to 50 mm/s;
– protecting danger zones by means of appropriate guards;
– maintaining moving parts securely in position – even in the case of a fault.
If the appliance or part is tilted manually, it shall not be possible to adversely influence the
tilting action other than by the intended means.

Compliance is checked by inspection and by applying a force of 340 N at any point on the
tiltable part.
20.106 In the requirement paragraph and in the first and second dash of the Note, replace
the words "piece holder" with "product holder". In the third dash of the Note, replace the
word "slicers" with "systems".
Page 29
20.107 Replace this subclause with the following new subclause:
20.107 Accidental contact with devices of driven shafts which engage on attachable
accessories shall be prevented, unless their movement is possible only after attachable
accessories have been engaged.

– 6 – 60335-2-64 Amend. 1 © IEC:2000(E)

Compliance is checked by inspection and by manual test.

NOTE The requirement is considered to be met, for example, if the devices are recessed in their housing or are

constructed so that contact would not result in a hazard.

20.109 Replace this subclause with the following new subclause:

20.109 Blades of hand-held blenders shall be completely screened from above and shall not
be able to touch a flat surface when rotating.

Compliance is checked by inspection and by applying a cylindrical rod from any position
between the vertical and an angle of 45° to the upperside of the blending blade. The rod has
a diameter of 8,0 mm ± 0,1 mm and unlimited length.
It shall not be possible to touch the blades with the end of the test rod.
20.110 Replace this subclause with the following:
20.110 Appliances for washing and drying foodstuffs, which have a rotating drum with a
kinetic energy of more than 200 J, shall be provided with a cover interlocked so that the
appliance will not start when the cover is open. If the cover is opened while the appliance is
operating, the drum shall stop within 2 s.
Compliance is checked by inspection, measurement and manual test. The appliance is
supplied at rated voltage and without a load.
20.111 Replace this subclause with the following:
20.111 Dangerous moving parts which are accessible after covers or lids are opened shall
stop within 2 s after the cover or lid has been opened or removed. When closed again, the
automatic restarting of the appliance shall be possible only if this does not result in a hazard.
Compliance is checked by operating the appliance without load and at the highest speed.
Add the following additional subclauses:
20.113 Hand-held whisks shall be provided with a guard to avoid accidental slipping of the
hand into the tool. Its dimensions shall be at least 30 mm greater than the dimensions of the
handgrip zone, and it shall be located between the handgrip zone and the tool.
Compliance is checked by inspection, measurement and manual test.

20.114 Beam mixers shall automatically switch off when the head is raised to a height of
300 mm above the supporting surface, unless the appliance incorporates a switch which has
to be kept switched on by hand.

20.115 Unloading of the product from peelers shall not cause a hazard.

Compliance is checked by inspection and manual test.

NOTE The requirement may be met by, for example

– suitable guards preventing contact, except by a deliberate action, with rotating plates involving hazards of trap

or injury;
– for rotating plates provided with cutting blades, the need to use one hand to keep the discharge door or lid

open and the provision of a switch which has to be kept switched on by hand to allow for unloading of the product.

20.116 Slicing machines shall be stable when in use.

NOTE 1 This requirement does not apply to fixed appliances.
Compliance is checked by the following test:
The slicing machine is placed in accordance with the instructions for use on a plain glass
plate which is placed on a horizontal surface.
NOTE 2 The glass surface is prevented from sliding by a stop.
A force of 50 N is applied horizontally to the appliance in the most unfavourable direction at a
point 10 mm below the upper surface of the base carrying the sliding feed table.
