CEN/TC 126/WG 11 - Test code for suspended ceilings
Develop a new acoustic test code for suspended ceilings Identify the laboratory test configuration details that will have an influence on the acoustic performances. Identify the relevant measurement methods to evaluate the acoustic properties of each element that composes the suspended ceiling system. Identify the mounting details on laboratory that will have an influence on the acoustic performances. This working group will organize a round robin test to quantify the uncertainty. Then the working group will prepare a test code that will give the level of uncertainty of the acoustic measurement on laboratory of a suspended ceilings and on absorption coefficient and flanking transmission

The European Committee for Standardization (CEN) is a public standards organization that brings together the national standardization bodies of 34 European countries. CEN provides a platform for developing European Standards (ENs) and other technical documents in relation to various products, materials, services, and processes, supporting the European Single Market.
A Working Group in CEN is a specialized group responsible for developing standards or technical work within a defined scope. These bodies bring together international experts to create consensus-based standards that support global trade, safety, and interoperability.
This European Standard specifies additional necessary information on how to carry out efficiently and under standardized conditions the determination of the sound absorption coefficients according to EN ISO 354 “Measurement of sound absorption in a reverberation room”. It specifies the additional requirements of the sound absorption measurements and the operating and mounting conditions that should be used for the test. Observe that all demands in EN ISO 354 still should be fulfilled. The results obtained are used for design calculations with respect to room acoustics and to convert frequency-dependent sound absorption coefficients into a weighted sound absorption coefficient αw, according to EN ISO 11654.
This European Standard is applicable for the compile of the single number rating αw, to express the sound absorption performance of suspended ceiling membranes in CE marking and labelling according to EN 13964. This European Standard is not applicable for suspended ceiling kits according to EN 13964.
