Acoustics - Test code for drywall systems of plasterboard with steel studs - Airborne sound insulation

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.

Overview - What EN 16703:2015 covers

EN 16703:2015 is a CEN test code for measuring airborne sound insulation of drywall systems made from plasterboard with steel studs. It complements EN ISO 10140-1/2 by adding specific, stricter rules and practical guidelines to improve reproducibility of laboratory measurements of the sound reduction index R. The standard specifies mounting, perimeter treatment, test element size, and a laboratory validation method using two reference test partitions. Results are converted into single-number ratings per EN ISO 717-1 and can be used as input for estimation methods such as EN 12354-1.

Key topics and technical requirements

• Scope and intention
  • Applies to non-load-bearing metal frame partitions with plasterboard and steel studs.
  • Intended to decrease inter-laboratory uncertainty for airborne sound insulation tests.
• Test element and size
  • Recommended partition test area: 9 m2 – 12 m2.
• Boundary and mounting conditions
  • Test element must be mounted directly in the laboratory opening (not a prefabricated full partition).
  • Leave a 5–10 mm gap between board edges and the reveal; fill with appropriate material and respect drying times.
  • Position relative to the laboratory acoustic break and niche depth is critical - partitions should normally be installed on the same side of the break with niche depth ratio 2:1 to improve reproducibility.
• Validation of laboratories
  • Mandatory preliminary tests with two reference test partitions (detailed in Annexes B and C).
  • Materials for reference partitions must meet specified product properties; measurements taken ≥12 hours after installation.
  • Acceptance criteria include band-by-band envelopes and a summed-deviation limit (sum of deviations not to exceed 4 dB).
• Test reporting
  • Builds on EN ISO 10140-2 reporting requirements and requires additional details: perimeter treatments, putty type and drying time, fastener details, and exact partition position (Annex A).

Applications - Who uses EN 16703:2015

• Acoustic testing laboratories - to standardize measurement procedures and validate lab performance.
• Gypsum/plasterboard and metal framing manufacturers - to demonstrate airborne sound performance for product comparison and CE marking.
• Acoustic consultants and specifiers - to select systems and interpret laboratory R-values and single-number ratings.
• Regulatory bodies and certification schemes - for harmonized assessment of partition sound insulation.

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

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 %.
For more information about handling uncertainty refer to ISO 12999-1. SIST EN 16703:2015

Reference test partition location in aperture A.1 General This annex has two objectives: — to define with precision the location of the partition when validating the laboratory with the two reference test partitions; — to simplify the description of the partition's location in test report. To ensure a good reproducibility the specimen has to be installed on source side, and its location has to be reported with the letters representing the following privileged configuration. A.2 Case A “Aperture without niche and one acoustic break” Case A is the configuration with an aperture without a niche and with one acoustic break; see Figure A.1.

In case where the application of the rules 2:1 makes the partition locate on the acoustic break, then move the partition to the source side of the break.
