EN 16703:2015 (E) 4 European foreword This document (EN 16703:2015) has been prepared by Technical Committee CEN/TC 126 “Acoustic properties of building elements and of buildings”, the secretariat of which is held by AFNOR. 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of an identical text or by endorsement, at the latest by March 2016, and conflicting national standards shall be withdrawn at the latest by March 2016. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN [and/or CENELEC] shall not be held responsible for identifying any or all such patent rights. This standard is a complement to the European Standard EN ISO 10140-1 and is not intended to replace it. The complement includes more stringent rules, narrower tolerances and new, additional requirements. According to the CEN-CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United Kingdom.

EN 16703:2015 (E) 5 Introduction Product standard EN 520:2004+A1:2009 “Gypsum plasterboards – Definitions, requirements and test methods” specifies requirements and test methods and establishes how to declare characteristics and to affix the CE marking of products accordingly. In EN 520:2004+A1:2009, when a drywall partition with plasterboard and steel studs has an airborne sound insulation performance property, its sound reduction should be determined in accordance with EN ISO 140-3, now replaced by EN ISO 10140-2. The measured sound reductions are calculated into sound reduction index R, in third octave bands and into single number indexes, in accordance with EN ISO 717-1. Those single number ratings are used for the CE marking. Measurement of sound reduction according to EN ISO 10140-2 was known through earlier inter laboratory tests (ILT), to generate large spread in results from different laboratories. This was not suitable, either from a competition point of view or from an end-user perspective. Therefore, CEN/TC 126 “Acoustic properties of building elements and of buildings” decided to set up a working group, WG 9 “Test Code for drywall partition with plasterboard and steel studs”, with the scope to improve reproducibility by developing a Test Code complementary to the EN ISO 10140-1. One part of this work was to organize ILT for sound reduction measurements, to assess the uncertainty of acoustic quantities (Annex D). This was used by the working group to prepare this test code for drywall systems, including guidelines of testing installation and validation of laboratory, to decrease the level of uncertainty. SIST EN 16703:2015
EN 16703:2015 (E) 6 1 Scope This European Standard specifies information additional to EN ISO 10140-1 necessary to carry out efficiently and under standardized conditions the determination of the sound reduction index of drywall systems of plasterboard with steel studs according to EN ISO 10140-2 “Acoustics — Laboratory measurement of sound insulation of -building elements — Part 2: Measurement of airborne sound insulation”. Observe that all demands in EN ISO 10140-2 should still be fulfilled. In order to decrease the uncertainty, it specifies: — additional guidelines for testing drywall systems of plasterboard with steel studs; and — a method to validate laboratory by using two reference test partitions. The results obtained are used to convert frequency-dependent sound reduction index into single number ratings, according to EN ISO 717-1. These performances can be used to compare different products, or, and to express a requirement, or, and as input into estimation methods, such as EN 12354-1. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. EN 520:2004+A1:2009, Gypsum plasterboards — Definitions, requirements and test methods EN 13162, Thermal insulation products for buildings — Factory made Mineral wool (MW) products — Specification EN 13963, Jointing materials for gypsum boards — Definitions, requirements and test methods EN 14195, Metal framing components for gypsum board systems — Definitions, requirements and test methods EN 14566, Mechanical fasteners for gypsum plasterboard systems — Definitions, requirements and test methods EN ISO 10140 (all parts), Acoustics — Laboratory measurement of sound insulation of building elements (ISO 10140, all parts) 3 Terms and definitions For the purposes of this document, the following term and definition apply. 3.1 drywall system of plasterboard with steel studs partition comprising a non load bearing metal frame partition enclosed by plasterboards SIST EN 16703:2015
EN 16703:2015 (E) 7 4 Test code for drywall systems of plasterboard with steel studs 4.1 Application 4.1.1 This standard applies to non-load bearing metal frame partition comprising a metal frame enclosed by plasterboards. In general, the type, size, gauge and spacing of the studs, and the size, type and number of layers of plasterboard and eventual amount and type of cavity filling material in partition constructions are determined by the performance requirements of the system. 4.1.2 The quantity to be determined is the sound reduction index R as a function of frequency. The definition of R is given in EN ISO 10140-2. 4.2 Testing Guidelines 4.2.1 Test element The partition size shall be between 9 m2 – 12 m2. For all others information, refer to EN ISO 10140-1 and EN ISO 10140-2. 4.2.2 Boundary and mounting conditions 4.2.2.1 General rules The test element shall be mounted directly on the facilities frame; it shall not be a prefabricated full partition. The test element should be installed in a similar manner to the actual construction with careful simulation of typical connections and sealing conditions at the perimeter and at all joints. 4.2.2.2 Perimeters mounting A gap of about 5 mm to 10 mm shall remain between the plasterboards and the reveal of the test opening. This gap shall be filled with appropriate material. Drying time has to respect product instruction according to 4.3.1 because the type of filler will have an influence on the performance of the partition. Cracks in the perimeter may occur, resulting in air leakage. To control risk a procedure shall be set in the laboratory to check this. This shall be at minimum a visual control but can also be any additional method. 4.2.2.3 Partition positions The sound reduction index of drywall system of plasterboard with steel studs is influenced by the mounting conditions in the test opening of the laboratory. Important installation parameters include the niche depth and the position of the partition in relation to the acoustic break in the test aperture. The partition shall be installed into the test opening so that the niches on both sides of the partition have different depths with a ratio of 2:1. To improve the reproducibility between laboratories and facilitate comparison of sound reduction indices for different drywall system of plasterboard with steel studs, the partition (even double wall) shall not be mounted across the acoustic break between sending and receiving room of the laboratory, but on the same side of the break as indicated in Annex A. Main mounting conditions are reported in Annex A; others may be used but shall be fully described in the test report. SIST EN 16703:2015
EN 16703:2015 (E) 8 NOTE Mounting the lightweight partition with one leaf on one side and the other leaf on the other side of the acoustic break can result in higher values for the sound reduction index. Other mounting conditions may be suitable for certain types of twin leaf walls, for example, walls for semidetached houses where the leaves are vibrationally uncoupled (for example on separate foundations). In such cases the wall leaves can be mounted on each side of the acoustic break. No absorption material should be located close (less than 1 m) to the perimeter of the partition. The acoustic break has to be covered with soft reflecting materials. 4.2.3 Test report The test report shall include the information listed in EN ISO 10140-2:2010, Clause 9 and the following additional information shall also be reported: a) detailed description of the perimeters treatments; b) detailed description of the putty used and its drying time; c) detailed description of the fasteners used (screws spacing, stud centre) including perimeter frame; d) detailed description of the partition position ; it is recommended to refer to Annex A. 4.3 Validation of the laboratory with two reference test partitions 4.3.1 Test elements To reduce expanded uncertainty in a reproducibility condition of drywall plasterboard partition with steel stud, it is required to conduct preliminary tests with two laboratory reference test partitions described in Annexes B and C. The materials used to conduct these reference test partition tests should be products in accordance with the properties reported in Tables B.1 and C.1. The properties of the products mentioned shall be measured using the methods within the relevant product standard except for the E-modulus properties. The position of the reference test partitions shall be in accordance with Annex A. The installation of the reference test partitions shall be in accordance with the Annex B (partition type 1) and Annex C (partition type 2). The measurement shall be done at least 12 h after installation in accordance with EN ISO 10140-2. 4.3.2 Acceptance criteria 4.3.2.1 General Tables 1 and 2 define the envelope of partition type 1 and type 2 respectively. The acceptance criteria is met if the measured spectra for both reference test partitions are within the envelopes presented below or the sum over all third octave bands of the deviations between the measured and the envelope values does not exceed 4 dB (see 4.4 for further information on uncertainty values and how to apply). The deviation of 4 dB has been decided to take into account modal behaviours in low frequency and where critical frequency has influenced the sound reduction. This has been observed to be influenced by both laboratory configuration origin and plasterboard stiffness. If the local minimum around the critical frequency is not in the 3150 Hz third octave band, it is recommended to control the value of the E modulus of the plasterboard to be close to the ones that have been tested initially for the laboratory SIST EN 16703:2015

NOTE Other parameters like changing loudspeaker and microphone positions can be a way to reach the criteria. These remedial actions should be applicable for both reference test partitions and shall be applied for all further testing. SIST EN 16703:2015
EN 16703:2015 (E) 11 4.4 Application of uncertainties If the testing guidelines are applied, the laboratory is validated as above and the acceptance criteria for the two reference test partitions are met then the standard uncertainties values given in the table below can be applied. Table 3 — Standard uncertainties u of single number quantities Single number Standard uncertainty in a reproducibility condition u (dB) Rw 0,7 Rw+C 0,7 Rw+C tr 1,1 For measurement results obtained in accordance with the EN ISO 10140 (all parts), the expanded uncertainty U shall be calculated by: U = k u [1] where U is the expanded uncertainty calculated for a given confidence level for the two-sided test 95 %; u is the standard uncertainty determined in Table 3 of this standard; and k is the coverage factor. Its value depends on the distribution of the possible values of the measure and on the confidence level.
For the purpose of this standard it is assumed that the values of the k = 2. A measurement result shall then be stated as follows: Y = y ± U [2] where Y is the measurand (Rw, Rw+C, Rw+Ctr); y the best estimate found by the measurement; U is the expanded uncertainty calculated for a given confidence level for the two-sided test 95 %.

Introduction
Product standard EN 520 “Gypsum plasterboards – Definitions, requirements and test methods” specifies
requirements and test methods and establishes how to declare characteristics and to affix the CE marking of
products accordingly. In EN 520, when a drywall partition with plasterboard and steel studs has an airborne
sound insulation performance property, its sound reduction should be determined in accordance with
EN ISO 140-3, now replaced by EN ISO 10140-2 and EN ISO 717-1. The measured sound reductions are
calculated into sound reduction index R in third octave bands and into single number indexes, in accordance
,
with EN ISO 717-1. Those single number ratings are used for the CE marking.
Measurement of sound reduction according to EN ISO 10140-2 was known, through earlier interlaboratory
tests (ILT), to generate large spread in results from different laboratories. This was not suitable, either from a
competition point of view or from an end-user perspective. Therefore CEN/TC 126 “Acoustic properties of
building elements and of buildings” decided to set up a working group, WG 9 “Test Code for drywall partition
with plasterboard and steel studs”, with the scope to improve reproducibility by developing a Test Code. One
part of this work was to organize ILT for sound reduction measurements, to assess the uncertainty of acoustic
quantities. Then the working group prepared the test code presented in this standard that gives the level of
uncertainty of the acoustic measurement in laboratories of a drywall system of plasterboard with steel stud.

1 Scope
This draft European Standard specifies additional information necessary to carry out efficiently and under
standardized conditions the determination of the sound reduction index of drywall systems of plasterboard
with steel studs according to EN ISO 10140-2 “Acoustics — Laboratory measurement of sound insulation of
building elements — Part 2: Measurement of airborne sound insulation”. It specifies the additional
requirements of the sound reduction measurements, the operating and mounting conditions that shall be used
for the test and additional test report information to be reported. Observe that all demands in EN ISO 10140-2
still must be fulfilled. The results obtained are used to convert frequency-dependent sound reduction index
into single number ratings, according to EN ISO 717-1. These performances can be used to compare different
products, or, and to express a requirement, or, and as input into estimation methods, such as the series
EN 12354-1.

4 Test code for drywall systems of plasterboard with steel studs
4.1 Application
4.1.1 This standard applies to non-load bearing metal frame partition comprising a rigid metal frame
enclosed by boards.
In general, the type, size, gauge and spacing of the studs, and the size, type and number of layers of
plasterboard and eventual amount and type of cavity filling material in partition constructions are determined
by the performance requirements of the system.
4.1.2 The quantity to be determined is the sound reduction index R as a function of frequency. The
definition of R is given in EN ISO 10140-2.
4.2 Test element
2 2
The test opening for walls should be 10 m (+/- 1 m ).
For all others information, refer to EN ISO 10140-2.
4.3 Boundary and mounting conditions
4.3.1 General rules
The test mounting should be mounted directly on the facilities frame; it cannot be a prefabricated full partition.
The test element should be installed in a similar manner to the actual construction with careful simulation of
typical connections and sealing conditions at the perimeter and at all joints.
4.3.2 Perimeters mounting
A gap of about 5 mm to 10 mm shall remain between the panel and the reveal of the test opening. This gap
shall be filled with appropriate material. Drying time has to respect product instruction according to 4.3.1. The
type of putty will have an influence on performance of the partition.
Cracks in the perimeter may occur, resulting in air leakage. A control procedure has to be set in laboratory to
avoid risk.
4.3.3 Partition positions
The sound reduction index of lightweight especially for twin leaf partitions (e.g. twin leaf gypsum board walls)
is influenced by the mounting conditions in the test opening of the laboratory. Important installation
parameters include the niche depth and the position of the partition in relation to the acoustic break in the test
aperture.
The partition shall be installed into the test opening so that the niches on both sides of the partition have
different depths with a ratio of 2:1.
To improve the reproducibility between laboratories and facilitate comparison of sound reduction indices for
different lightweight walls, the partition (even double wall) shall not be mounted across the acoustic break of
the laboratory, but on the same side of the break as indicated in Figure C.1 Partition example.
Main mounting conditions are reported in Annex C other may be used but shall be fully described in the test
report.
NOTE Mounting the lightweight partition with one leaf on one side and the other leaf on the other side of the acoustic
break can result in higher values for the sound reduction index.
Other mounting conditions may be suitable for certain types of twin leaf walls, for example, walls for
semidetached houses where the leaves are vibrationally uncoupled (for example on separate foundations). In
such cases the wall leaves can be mounted on each side of the acoustic break.
No absorption material should be located close (less than 1 meter) to the perimeter of the partition. The
acoustic break has to be covered with soft reflecting materials.

4.4 Test and operating conditions
4.4.1 Standard uncertainties
To reduce expanded uncertainty in a reproducibility condition of drywall plasterboard partition with steel stud,
it is required to realize preliminary tests with two laboratory reference partitions described in Annexes A and B.
If the measured spectra fall within the envelopes presented below or the sum over all third octave bands of the
deviations between the measured and the envelope values does not exceed 4 dB it could be assumed that
the expanded uncertainty of R ; R + C and R + C of further measurements will be taken from Table 1.
w w w tr
The deviation of 4 dB has been decided to take into account of modal behaviours in low frequency but also for
the frequency where critical frequency has influenced the sound reduction. It has been observed both
laboratory configuration origin and panel stiffness. For the panel if critical frequency is not in the third octave
3150 Hz, it is recommended to control with the value of the E modulus to be at +/- 20% of what has been used
for the initial qualification of this method (see Annexes E and F)
Thanks to those preliminary tests, Table 1 and 2 could be used to give the standard uncertainties in a
reproducibility condition for airborne sound insulation in one third-octave bands are given and for different
single-number quantities.

For measurement results obtained in accordance with the ISO 140 series, the expanded uncertainty U shall
be calculated by:
U = k u
Where
u is the standard uncertainty determined in Table 1 and 2 of this standard; and
k is the coverage factor. Its value depends on the distribution of the possible values of the measurand
and on the confidence level.
For the purpose of this standard it is assumed that the values of the k is fixed at 2.
A measurement result shall then by stated as follows
Y= y ± U
Where
Y is the measurand, y the best estimate found by the measurement; and
U is the expanded uncertainty calculated for a given confidence level for the two-sided test 95 %.
For all other information refer to EN ISO 10140-2 and ISO 12999-1.
4.4.2 Diffusivity conditions
The diffusivity of the sound fields in the source and receiving room has been identified as one parameter that
can reduce the expanded uncertainty.
Large variations of the sound pressure level in the room indicate the presence of dominating strong standing
waves. EN ISO 10140-5 already imposes to have diffuse field conditions by proposing to install diffusing
elements in the rooms, it requires to ensure that the positioning and number of diffusing elements should be
arranged so that the sound reduction index is not influenced when further diffusing elements are installed.
In order to evaluate the diffuse field condition, put two additional simple diffusers as plasterboard panels (1,2 m x 2,4 m)
for each room (source and receiving room). Install them with two different slopes and according to the EN ISO 10140-5
section 3.2.2 specifications (minimum distance to microphone and loudspeaker and test specimen) preferably on the back
of the chamber.
To confirm the diffusivity, do the test with these two additional simple diffusers and check that results are
within the internal repeatability limits of the laboratory. Continue until results are inside the internal
repeatability of the laboratory. When necessary, add further diffusers.

A.2 Installation procedure of partition Type 1
A.2.1 Installation of framework with channels and studs
The framework consists of horizontal channels and vertical studs. 72 mm channels are fixed to the bottom and
top of the aperture using 44 mm screws and plastic plugs at nominal 500 mm centres, along the centre of the
channel. The first and last fixing should be located 100 mm from the corner. Please note that no material
(foam strip, sealant etc.) should be applied in between the channel web and the aperture. Channel joints
should be done as a butt joint i.e. the channels are put end to end (no overlap). There should be a fixing at
100 mm from the joint, on both sides of the joint. Cut the studs so the length is 10 mm shorter than the height
of the partition. Fix the first and last stud to the concrete frame of the aperture. The fixings of these studs are
done in the same manner as for the channel i.e. using 44 mm screws and plastic plugs at nominal 500 mm
centres along the centre of the stud. The first and last fixing should be located 100 mm from the corner.
Please note that no material (foam strip, sealant etc.) should be applied in between the stud web and the
aperture. Place the remaining studs between top and bottom channel at 600 mm centres. Start at side A and
turn all the studs so that they have the web in the same direction as the first stud (at side A). The studs should
not be fixed to the top and bottom channels. The distance from the aperture (at side A) to centre of the flange
of the second stud should be 600 mm. To facilitate the installation of plasterboards, mark the position of the
centre of the studs on the bottom and the top of the aperture.

A.2.2 Installation of Plasterboards 1 side
The plasterboards should be cut so that there will be a 5 mm clearance on the lateral and top edges of the
partition and a 5 mm to 10 mm clearance at the bottom. Cut vertical edges of plasterboards are only allowed
on the first and last stud that is fixed to the aperture edges. All other vertical plasterboards edges should be
tapered edges. The plasterboards should be butt-jointed i.e. without any gap between the tapered edges of
the boards. Mark the positions of the screws on the board following the description below. When fully screwed
the boards should be screw fixed as follows: the screws along the edges of the board should be 10 mm from
the edge of the plasterboard. The boards should be screw fixed into the edge studs and intermediate stud at
300 mm centres. The top and the bottom screw should be located 100 mm from the top and the bottom end of
the board. The board should be fixed to the channel at top and bottom with one screw located half way
between the studs and 15 mm from the board end. Before screw fixing the plasterboard make sure your screw
driver is set so that the screw depth will be correct i.e. the screw head should be flush with the plasterboard.
The boards should be fixed using 25 mm screws. If by mistake, a screw is not catching the metal, the screw
should be removed and the hole later filled with jointing material. For the installation of plasterboards cut 5 mm
off the left hand edge of the first board (so that there will be a 5 mm clearance to the aperture on the left hand
side of the board and the right hand tapered edge of the board will be positioned at the middle of the flange of
the third stud). Stand the plasterboard on a 5 mm to 10 mm block to ensure the clearance of the bottom. To
ensure the verticality of the studs, only fix the board to the edge studs on the first side of the partition. Fixing to
the intermediate stud is done after board have been fixed at the second side of the partition. Install the
remaining boards
