18、 by Technical Committee CEN/TC 126 “Acoustic properties of building products 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 June 2004
19、, and conflicting national standards shall be withdrawn at the latest by June 2004. This document is the first version of a standard which forms a part of a series of standards specifying calculation models in building acoustics: Part 1: Airborne sound insulation between rooms Part 2: Impact sound i
20、nsulation between rooms Part 3: Airborne sound insulation against outdoor sound Part 4: Transmission of indoor sound to the outside Part 5: Sound levels due to service equipment Part 6: Sound absorption in enclosed spaces Although this part covers the most common types of enclosed spaces in building
21、s it cannot yet cover all variations of such spaces. It sets out an approach for gaining experience for future improvements and developments of the standard. The accuracy of this standard cannot be specified in detail until wide ranging comparisons with field data have been made, which can, in turn,
22、 only be gathered over a period of use of the prediction model. To help the user in the meantime, indications of the accuracy have been given, based on earlier comparable prediction models. It is the responsibility of the user (i.e. a person, an organisation, the authorities) to consider the consequ
23、ences of the accuracy, inherent in all measurement and prediction methods, to specify requirements for input data and/or apply a safety margin to the results or to apply some other correction. Annex A is normative, annexes B, C, D and E are informative. According to the CEN/CENELEC Internal Regulati
24、ons, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Czech Republic, Denmark, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Luxembourg, Malta, Netherlands, Norway, Portugal, Slovakia, Spain, Sweden
