This European Standard shall be given the status of
19、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of an identical text or by endorsement, at the latest by March 2016, and conflicting national standards shall be withdrawn at the latest by March 2016.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 pa

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
21、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 Macedoni

BS EN 16703:2015EN 16703:2015 (E) 5 Introduction Product standard EN 520:
23、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 stud
24、s 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 accord
25、ance 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 co
26、mpetition 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 develop
27、ing 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 testi
28、ng installation and validation of laboratory, to decrease the level of uncertainty. BS EN 16703:2015EN 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 soun
29、d 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 or
30、der 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 singl
31、e 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 i

35、wing 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 BS EN 16703:2015EN 16703:2015 (E) 7 4 Test code for drywall systems of plasterboard with steel studs 4.1 Application 4.1.1 This
36、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 cons
37、tructions 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
38、 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 simi
39、lar 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
40、 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
41、 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 installa
42、tion 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 reprodu
43、cibility 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
44、 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. BS EN 16703:2015EN 16703:2015 (E) 8 NOTE Mounting the lightweight partition with one leaf on one side and the other leaf on the other side of t
45、he 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 th
46、e 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 list
47、ed 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) includ
48、ing 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
49、 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 referen
