Foreword
This document (EN 13819-1:2002) has been prepared by Technical Committee CEN/TC 159, "Hearing protectors",
the secretariat of which is held by SIS.
This European Standard shall be given the status of a national standard, either by publication of an identical text or
by endorsement, at the latest by June 2003, and conflicting national standards shall be withdrawn at the latest by
June 2003.
This document has been prepared under a mandate given to CEN by the European Commission and the European
Free Trade Association, and supports essential requirements of EU Directive(s).
For relationship with EU Directive(s), see informative annex ZA, which is an integral part of this standard.
In this European Standard the annex A is informative.
According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following
countries are bound to implement this European Standard: Austria, Belgium, Czech Republic, Denmark, Finland,
France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Malta, Netherlands, Norway, Portugal, Spain,
Sweden, Switzerland and the United Kingdom.
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 Directive 89/686/EEC - Personal Protective Equipment.
EN 352-1 deals with requirements for ear-muffs, EN 352-2 with ear-plugs, EN 352-3 with ear-muffs attached to
industrial safety helmets. EN 13819 deals with testing plans common to all types of hearing protectors and
consists of two Parts:
Part 1: Physical test methods
Part 2: Acoustic test methods.
Additional safety requirements and the associated test procedures for level-dependent ear-muffs are contained in
EN 352-4, for ear-muffs with active noise reduction in EN 352-5, for ear-muffs with audio communications in
EN 352-6 and for level-dependent ear-plugs in EN 352-7.
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 protection standard.
1 Scope
This European Standard EN 13819-1 specifies physical test methods for hearing protectors. The purpose of these
tests is to enable assessment of the performance of the hearing protector as specified in the appropriate product
standard.
2 Normative references

normative references are cited at the appropriate places in the text and the publications are listed hereafter. For
dated references, subsequent amendments to or revisions of any of these publications apply to this European
Standard only when incorporated in it by amendment or revision. For undated references the latest edition of the

3 Terms and definitions
For the purposes of this European Standard, the following terms and definitions apply, in addition to those given in
EN 352 parts 1,2 and 3.
3.1
headband ear-muffs
ear-muffs satisfying the requirements of EN 352-1.
3.2
helmet mounted ear-muffs
ear-muffs fitted to a helmet such that the combination satisfies the requirements of EN 352-3.
3.3
1)
test height
vertical distance between the axis through the centres of the mounting holes of the pinna simulators in the
mounting fixture or test headform shown in Figures 3 or 4 respectively, and the top of the headband support pad or
headform.


 













 
3.4
1)
test width
horizontal distance between the vertical axes through the centres of the mounting holes for the pinna simulators in
the mounting fixture or test headform shown in Figure 3 or 4 respectively.
3.5
1)
test depth
vertical distance between the axis through the centres of the mounting holes of the pinna simulators and the top of
the headband support, with the pinna simulators attached with their shorter axes vertical shown in Figure 3.
3.6
wearing height
vertical distance from the lower edge of the headband of the helmet to the highest point of the test headform on
which the helmet is mounted.
NOTE The headband of the helmet is defined in EN 397 as "The part of the harness completely or partly surrounding
the head above the eyes at approximately the largest horizontal circumference of the head".
4 Ear-muffs
4.1 Specimens, conditioning and scheme of testing
4.1.1 Specimens
Headband ear-muffs and helmet mounted ear-muffs shall be submitted for testing in the condition in which they are
offered for sale.
For headband ear-muffs, 10 specimens shall be submitted and they shall be numbered 1 to 10.
For helmet mounted ear-muffs, 10 basic combination specimens (ear-muffs and helmets) shall be submitted and
they shall be numbered 1 to 10 (basic).
If the same model of helmet mounted ear-muffs is to be tested with another model or size of helmet, 6 further
supplementary combination specimens (ear-muffs and helmets) for each model or size of helmet shall be
submitted. These shall be numbered (in sets) 1 to 6 (supplementary).
4.1.2 Conditioning and testing atmosphere
All specimens shall be conditioned and tested in an atmosphere having a temperature of (22 ± 5) °C and a relative
humidity of not more than 85 %, unless required otherwise by the test procedure.
4.1.3 Scheme of testing
4.1.3.1 The 10 headband ear-muffs shall be conditioned and tested in accordance with 4.1.3.2 to 4.1.3.9 and
Figure 1.
For helmet mounted ear-muffs, except as specified in the following paragraph, the scheme of testing for the 10
basic combination specimens and, if applicable, the sets of 6 supplementary combination specimens, shall be as
given in 4.1.3.2 to 4.1.3.9 and Figure 2.


 













 
In the case of helmets supplied in more than one size, one selected size shall be used for testing in a basic
combination (except for sound attenuation testing). All other helmet sizes shall be tested in a supplementary
combination (except for sound attenuation testing). Sound attenuation testing shall be performed using the
complete range of available helmet sizes (see EN 13819-2). If the helmet mounted ear-muff incorporates a means
to adjust the headband force, the force shall be adjusted to its minimum setting for all stages of conditioning and
testing, unless otherwise specified.
NOTE Testing may be discontinued in the event of a specimen failing to satisfy the respective requirement.
4.1.3.2 Unpack all ear-muffs completely.
4.1.3.3 For helmet mounted ear-muffs, each specimen shall be weighed and the mean mass of the 10 specimens
shall be reported to the nearest gram.
4.1.3.4 In the case of helmet mounted ear-muffs, the ear-muffs shall be attached to the helmets in accordanc
