NOTE For guidance in connection with risk reduction by design, see 6.2, and for safeguarding measures, see 6.3 of
EN ISO 12100:2010.
All guards shall be permanently attached to the machine and shall not be detachable without
the use of tools. The opening of guards shall require the use of a tool. Exceptions to this are
the opening or removal of interlocked guards which disable the protected moving parts, which
shall be in accordance with EN ISO 12100. The safety-related control system of the
interlocked guards shall comply at least with PL = c of EN ISO 13849-1:2008. The interlock
r
system shall cause the moving parts to come to a complete rest before access by the test
finger of test probe B of EN 61032:1998 can be gained. The interlock function may be
achieved by means of a switch. As a protection against the easy defeating of a switch used
for the interlock, it shall not be possible to actuate the switch with the test finger of test
probe B of EN 61032:1998 when the guard is open.

Compliance is checked by the methods given in EN ISO 13849-2:2012 and by manual tests
using the test finger of test probe B of EN 61032:1998 with a force not exceeding:
− 5 N for testing the actuation of the switch,
− 20 N for testing the accessibility to the moving parts.
For straight line access, apertures and safety distances shall conform to EN ISO 13857:2008, 4.2.4.1
and 4.2.4.3.
For curved access ways, hazardous moving parts shall not be accessible by means of any of the arm
probes shown in Figures 1 and 2.
Compliance is checked by inspection, measurement and, if applicable, the following tortuous path
test.
Each arm probe (see Figure 1 and Figure 2) shall not be able to make contact with the
hazardous moving parts when it is inserted into the openings up to the entire length of each
arm probe. The articulations of each probe shall be manufactured to enable a rotation of ± 90°
about the articulation axis. The movements of the joints of each probe shall be free enough to
allow easy articulation as the probe is inserted into the opening. Each probe shall be applied
with a force not exceeding 20 N.
Each arm probe shall be twisted and moved in any direction allowed by the joints when
approaching the hazardous moving parts. If necessary, one or more sections of the machine
may be cut away to allow the probe to be configured such that it penetrates as far as possible
towards the hazardous moving parts. If a section is removed this shall not allow the probe to
penetrate further than it would have done before the removal of the section(s).
The test shall be carried out both with and without the debris collector in place. If the
removal of the debris collector causes the power to the fan and/or shredding means to be
interrupted, the test shall only be done with the debris collector in place.
Both arm probes shall not contact the hazardous moving parts. When the test is conducted
with the debris collector in place it shall not be possible to push any part of the debris
collector into hazardous moving parts.

20.101 Handle
Hand held garden blowers, garden vacuums and garden blower vacuums shall have at
least one handle.
Additionally, machines with a mass of exceeding 6 kg shall have a harness according to
20.102.
The gripping length of any handle required by this standard shall be at least 100 mm.
The gripping length of a bail or closed handle shall comprise any length that is straight or
curved at a radius of greater than 100 mm together with any blend radius but not more than
10 mm at either or both ends of the gripping surface.
If a straight handle is supported centrally (i.e. 'T' type) the gripping length shall be calculated
as follows:
a) for handles with a periphery (not included the support) less than 80 mm the gripping
length is the sum of the two parts either side of the support;
b) for handles with a periphery (not including the support) of 80 mm or more the gripping
length is the complete length from end to end.
Where appropriate the part of the handle containing the machine control actuator shall be
counted as part of the handle gripping length. Finger grip or similar superimposed profiles
shall not affect the method of calculating handle gripping length.
The operator shall be able to switch off without releasing the hold on the machine.
Compliance is checked by inspection.
20.102 Harness
Machines with a mass of more than 6 kg shall be equipped with at least a single shoulder
harness. A double shoulder harness shall be provided for all machines exceeding 7,5 kg.
Single shoulder harnesses shall be designed in a way or be equipped with a quick release
mechanism that ensures that the machine can be released quickly from the operator in the
event of emergency. Double shoulder harnesses shall always have a quick release
mechanism. The quick release mechanism shall only allow separation by deliberate action of
the operator. The harness shall be adjustable to the size of the operator.
Machines exceeding 7,5 kg shall be supplied with a pad at the points of contact between the
machine and the body.
Compliance is checked by inspection and functional test.
20.103 Noise
20.103.1 Reduction by design and protective measures
The machine shall be so designed and constructed that risks resulting from the emission of
airborne noise are reduced to the lowest level taking account of technical progress and the
availability of means of reducing noise, in particular at source, see for example
EN ISO 11688-1:2009. The major sound sources are:

- air intake system;
- motor/engine cooling system;
- fan;
- vibrating surfaces;
- shredding means.
NOTE  The success of the applied noise reduction measures can be assessed on the bases of the actual noise
emission values in relation to other machines of the same family.
20.103.2 Reduction by information
Information on residual risks, after technical measures to control noise emission at the design
stage have been implemented, shall be given in the instruction handbook.
20.104 Vibration
20.104.1 Reduction by design and protective measures
The machine shall be so designed to generate vibration levels as low as practicable. The
main sources causing vibrations are the dynamic forces from motor, fan unbalanced moving
parts, impact in gear sprockets, bearings and other mechanisms and the interaction between
operator and machine.
NOTE  CR 1030-1:1995 gives general technical information on widely recognized technical rules and means and
can be used as a guideline for the design of reduced hand-arm vibration machines.
20.104.2 Reduction by information
Information on residual risks, after technical measures to control vibration emission at the
design stage have been implemented, shall be given in the instruction handbook.
20.104.3 Vibration measurement
The weighted acceleration sum shall be measured and calculated in accordance with
Annex BB.
21 Mechanical strength
This clause of Part 1 is applicable except as follows:
The impact energy shall be 1,0 J ± 0,05 J.
21.1.101 Requirements
The casing including all detachable guards shall have adequate mechanical strength and be
constructed to withstand such rough handling that may be expected in normal use.
Compliance shall be checked by the test in 21.1.102.

- 21 - EN 50636-2-100:2014
21.1.102 Casing strength and rigidity test of hand-held machines
The machine is rigidly supported and three blows are applied to every point of the casing that
is likely to be weak with an impact energy of 1,0 J ± 0,05 J by means of the spring hammer as
specified in EN 60068-2-75:1997.
To ensure that the machine is rigidly supported, it may be placed against a solid wall of brick,
concrete or similar material. In that case a sheet of polyamide is tightly fixed to the wall, care
being taken to ensure that there is no appreciable air gap between the sheet and the wall.
The sheet shall have a Rockwell hardness of HR 100, a thickness of at least 8 mm and be
sufficiently large to ensure that all parts of the machine are supported.
No parts of the guarding (casing) that are necessary for compliance with the requirements of
this European Standard shall have become detached and no visible cracks shall have
developed in these parts. It is not necessary for the machine to be operable after the test but,
if it is operable, then immediately following this test it shall be run at its maximum speed for
30 s and again, no parts of the machine that are necessary for safe operation shall become
detached and no visible cracks shall have developed in these parts.
If there is doubt as to whether a defect has occurred by the application of the preceding
blows, this defect is neglected and the group of three blows is applied to the same place on a
new sample which shall then withstand the test.
If an inner cover is protected by a decorative cover, the test shall be done with the decorative
cover removed.
Damage to the finish, small dents and small chips that do not adversely affect the function of
the guard are ignored.
Cracks not visible to the naked eye are ignored.
NOTE  Further tests for casing/fan strength are being investigated.
21.101 Structural integrity of vacuums
21.101.1 Requirements
The machine shall have sufficient structural integrity to withstand the rigours of normal
operation and break- up of the fan.
No part of the machine shall have become detached and there shall be no visible holes, tears
or cracks in the enclosure surrounding moving parts or in the debris collector.
Compliance shall be checked by the test in 21.101.2.

21.101.2 Structural integrity test
A structural integrity test shall be carried out on all machines by vacuuming up ceramic prisms
with triangular sides and a prism height of 6,5 mm ± 0,8 mm and a mass of 0,4 g ± 0,02 g
(see Figure 3).
