4.2 Adjustability
4.2.1 Principle
The ability of the earmuffs to be adjusted to fit specified test dimensions is assessed using a suitable
mounting fixture (headband earmuffs) or test headforms (mounted earmuffs).
4.2.2 Apparatus
4.2.2.1 Mounting fixture
The outline of an example is shown in Figure 5.
4.2.2.2 Test headforms
The test headforms shall be in accordance with the dimensions given in EN 960:2006, for sizes 505, 575
and 615 above the reference plane only and modified for width. Details are given in Figure 6 and
examples of mounted pinnas in Figures 7 and 8.
NOTE Additional parts of the headforms of EN 960:2006 can be used to support correct mounting of carriers
(e.g. the neck part).
4.2.2.3 Pinna simulators
The required dimensions are shown in Figure 10. A mounted pinna simulator is shown in Figure 11.
Alternatively, pinna simulators can be produced by 3D printing. An example is shown in Figure 12.
4.2.2.4 Non-planar cushion adaptor
For earmuffs with non-planar cushions, the manufacturer shall supply suitable adaptors which shall be
fitted to the mounting fixture, such that, when the earmuffs are fitted to the mounting fixture, and with
the plates of the latter set parallel, the centres of the openings of the earmuff cushions lie on the
horizontal axis through the centre of the force transducer.
4.2.3 Procedure
4.2.3.1 Headband earmuffs
4.2.3.1.1 Fit the pinna simulators to the plates of the apparatus so that their longer axes are vertical
for over-the-head and under-the-chin earmuffs or so that their shorter axes are vertical for behind-the-
head earmuffs (see Figure 7 resp. Figure 8 as examples).
4.2.3.1.2 Adjust the cups/headband to their longest position and, if the earmuffs incorporate a means
to adjust the headband force, adjust the force to its maximum setting.
4.2.3.1.3 Place the earmuffs on the fixture so that the headband is vertical and the pinna simulators
are enclosed by the cushions.
4.2.3.1.4 Adjust the separation of the plates and the height of the headband support to correspond in
turn with each of the combinations of dimensions of width and height respectively shown in Table 1 or
Table 2, as appropriate.
13

---------------------- Page: 15 ----------------------
SIST EN 13819-1:2021
EN 13819-1:2020 (E)
4.2.3.1.5 For each of the combinations of dimensions of width and height respectively, check whether
the range of adjustment of the cups/headband and of the width between the cushions enable the
earmuffs to be fitted so that:
a) for over-the-head earmuffs, the internal apex of the headband touches the headband support pad,
or, for behind-the-head or under-the-chin earmuffs, the internal apex of the headband touches or
lies beyond the headband support pad;
NOTE 1 Some earmuffs, because of their design, cannot be assessed correctly by this method. This applies for
example, to those behind-the-head earmuffs where the headband is designed to pass only around the back of
the neck. For these products this test is performed by using the appropriate test headforms as specified in
EN 960:2006, sizes 505, 575 and 615 (full headforms, including chin and neck), fitted with pinna simulators
at the heights given in Figure 6 appropriate to the earmuff size range.
b) the contact between the cushions and the plates of the fixture is continuous insofar as it provides
an unbroken barrier between the inside and outside perimeters of the cushions.
NOTE 2 Discontinuity in contact between the cushions and the plates is acceptable in the region where the
pinna simulator mounting area (46 mm × 10 mm) lies on the plates.
4.2.3.1.6 If the earmuffs incorporate a means to adjust the headband force, adjust the force to its
minimum setting and repeat steps 4.2.3.1.4 and 4.2.3.1.5.

NOTE 1 The dimensions given in Tables 1 and 2 have been chosen to cover appropriate combinations of the
head dimensions of the 5th, 50th and 95th percentiles of the adult population.
NOTE 2 If non-planar cushion adaptors are fitted to the mounting fixture, test width is the dimension between
the two outermost points of the cushion adaptors measured along the horizontal axis through the centre of the
force transducer.
4.2.3.2 Mounted earmuffs
4.2.3.2.1 Fit the pinna simulators to the side plates of the test headforms so that their longer axes are
vertical and coincident with the transverse vertical axis of the headform. Adjust their vertical position
as necessary to correspond with the test heights given in Table 3.
4.2.3.2.2 If the earmuff carrier incorporates a means to adjust the harness, adjust it to give the
maximum external vertical distance, in accordance with the carrier manufacturer’s instructions (see
Figure 9), making sure that the harness is still in contact with the test headform. Fit the mounted
earmuff to the test headform and measure the vertical distance between the ear canal entrance and the
external surface of the carrier shell (see Figure 9 and Figure 13) to be used in 4.3.3. If the carrier does
not include a shell measure the vertical distance between the ear canal entrance and the external
surface of the carrier.
NOTE This adjustment assumes continuing compliance of these dimensions with the requirements of the
relevant carrier standard (for example EN 397).
4.2.3.2.3 If the mounted earmuffs incorporate a means to adjust the headband force, adjust the force
to its maximum setting.
4.2.3.2.4 Place the mounted earmuff on each headform in turn, in the as-worn position, and so that
the pinna simulators are enclosed by the cushions. Maintain the carrier in position by the application of
a force of nominally 50 N acting along the vertical axis.
4.2.3.2.5 For each of the combinations of dimensions of width and height respectively shown in
Table 3, check whether the adjustment of the cups/cup supporting arms and of the width between the
cushions enable the mounted earmuff to be fitted to the fixture so that:
a) the contact between the cushions and the plates of the headform is continuous insofar as it
provides an unbroken barrier between the inside and outside perimeters of the cushions;

Introduction
This standard for ”Hearing Protectors — Testing — Part 1: Physical test methods”, specifies procedures
for the testing of personal hearing protection devices in relation to Regulation (EU) 2016/425 -
Personal Protective Equipment.
A family of standards EN 352 describes product requirements of hearing protectors:
— Part 1: Earmuffs
— Part 2: Earplugs
— Part 3: Earmuffs attached to head protection and/or face protection devices
— Part 4: Level-dependent earmuffs
— Part 5: Active noise reduction earmuffs
— Part 6: Earmuffs with safety-related audio input
— Part 7: Level-dependent earplugs
— Part 8: Entertainment audio earmuffs
— Part 9: Earplugs with safety-related audio input
— Part 10: Earplugs with entertainment audio input
Test methods for these requirements are described in the family of standards EN 13819:
— Part 1: Physical test methods
— Part 2: Acoustic test methods
— Part 3: Supplementary acoustic test methods
An associated standard EN 458 covers selection, use, care and maintenance of hearing protectors.
This standard is intended as a supplement to the specific product standards for hearing protectors.
The performance requirements are given in the hearing protector product standard.
If deviations from the procedures specified in this standard are necessary, these deviations are
specified in the hearing protector product standard (relevant part of the EN 352 series).
