This document specifies calculation models designed to estimate the airborne sound insulation between adjacent rooms in buildings, primarily using measured data which characterize direct or indirect flanking transmission by the participating building elements, and theoretically-derived methods of sound propagation in structural elements. A detailed model is described for calculation in frequency bands, in the frequency range 1/3 octave 100 Hz to 3 150 Hz in accordance with ISO 717-1, possibly extended down to 1/3 octave 50 Hz if element data and junction data are available (see Annex I); the single number rating can be determined from the calculation results. A simplified model with a restricted field of application is deduced from this, calculating directly the single number rating, using the single number ratings of the elements; a method to determine uncertainty is proposed for the simplified model (see Annex K). This document describes the principles of the calculatio
This document specifies calculation models designed to estimate the impact sound insulation between rooms in buildings, primarily using measured data which characterize direct or indirect flanking transmission by the participating building elements and theoretically-derived methods of sound propagation in structural elements. A detailed model is described for calculation in frequency bands, in the frequency range 1/3 octave 100 Hz to 3150 Hz in accordance with ISO 717-1, possibly extended down to 1/3 octave 50 Hz if element data and junction data are available (see Annex E); the single number rating of buildings can be determined from the calculation results. A simplified model with a restricted field of application is deduced from this, calculating directly the single number rating, using the single number ratings of the elements; the uncertainty on the apparent impact sound pressure level calculated using the simplified model can be determined according to the method described in ISO
This document specifies a calculation model to estimate the sound insulation or the sound pressure level difference of a fa?ade or other external surface of a building. The calculation is based on the sound reduction index of the different elements from which the fa?ade is constructed and it includes direct and flanking transmission. The calculation gives results which correspond approximately to the results from field measurements in accordance with ISO 16283-3. Calculations can be carried out for frequency bands or for single number ratings. The calculation results can also be used for calculating the indoor sound pressure level due to for instance road traffic (see Annex E). This document describes the principles of the calculation model, lists the relevant quantities and defines its applications and restrictions.
This document specifies a calculation model to estimate the sound power level radiated by the envelope of a building due to airborne sound inside that building, primarily by means of measured sound pressure levels inside the building and measured data which characterize the sound transmission by the relevant elements and openings in the building envelope. These sound power levels, together with those of other sound sources in or in front of the building envelope, form the basis for the calculation of the sound pressure level at a chosen distance from a building as a measure for the acoustic performance of buildings. The prediction of the inside sound pressure level from knowledge of the indoor sound sources is outside the scope of this document. The prediction of the outdoor sound propagation is outside the scope of this document. NOTE For simple propagation conditions an approach is given for the estimation of the sound pressure level in Annex E. This document describes the pri
This European Standard specifies the common requirements for safety and the (minimum) common performance requirements of firefighting and rescue service vehicles as designated in EN 1846-1.
(1)This Part 1-2 of EN 1996 deals with the design of masonry structures for the accidental situation of fire exposure, and is intended to be used in conjunction with EN 1996-1-1, EN 1996-2, 1996-3 and EN 1991-1-2.This part 1-2 only identifies differences from, or supplements to, normal temperature design.

(3)This Part 1-2 applies to masonry structures which, for reasons of general fire safety, are required to fulfil certain functions when exposed to fire, in terms of: avoiding premature collapse of the structure (load bearing function); limiting fire spread (flames, hot gases, excessive heat) beyond designated areas (separating function) (4)This Part 1-2 gives principles and application rules for designing structures for specified requirements in respect of the aforementioned functions and levels of performance. (5)This Part 1-2 applies to structures, or parts of structures, that are within the scope of EN 1996-1-1, EN 1996-2 and EN 1996-3 and are designed accordingly. (6)PThis Part 1-2 does not cover masonry built with Natural Stone units to EN771-6 (7)PThis Part 1-2 deals with the following; non-loadbearing internal walls; non-loadbearing external walls; loadbearing internal walls with separating or non-separating functions; loadbearing external walls with separating or non-separating functions.
This document describes calculation models to estimate the sound pressure level in buildings due to service equipment. As for the field measurement document (EN ISO 16032) it covers sanitary installations, mechanical ventilation, heating and cooling, service equipment, lifts, rubbish chutes, boilers, blowers, pumps and other auxiliary service equipment, and motor driven car park doors, but can also be applied to others equipment attached to or installed in buildings. The estimation is primarily based on measured data that characterises both the sources and the building constructions. The models given are applicable to calculations in frequency bands.This document describes the principles of the calculation models, lists the relevant quantities and defines its applications and restrictions. It is intended for acoustical experts and provides the framework for the development of application documents and tools for other users in the field of building construction, taking into account local circumstances. The calculation models described use the most general approach for engineering purposes, with a link to measurable quantities that specify the performance of building elements and equipment. The known limitations of these calculation models are described inThis document. Users should, however, be aware that other calculation models also exist, each with their own applicability and restrictions. The models are based on experience with predictions for dwellings and offices; they could also be used for other types of buildings provided the constructional dimensions are similar to those in dwellings.

La présente norme spécifie les méthodes d'essai, les exigences d'essai et les classifications applicables aux caissons de traitement d'air qui fournissent et/ou évacuent l'air par des réseaux de conduits, pour la ventilation/climatisation de tout ou partie de batiment. Elle ne s'applique pas aux équipements suivants : caissons de climatisation desservant une aire limitée d'un batiment comme les serpentins de ventilateurs ; caissons pour immeubles résidentiels ; caissons produisant de l'air de ventilation principalement pour un procédé de fabrication.Excepté en ce qui concerne les performances thermiques et acoustiques de l'enveloppe, les méthodes d'essai et les exigences s'appliquent à la fois au caisson complet et aux différentes sections.L'essai de dérivation du filtre ne s'applique pas aux filtres à air à très haute efficacité (HEPA).La méthode d'essai des performances thermiques de l'enveloppe peut être utilisée pour comparer différentes constructions, mais pas pour calculer les pertes thermiques à travers l'enveloppe, ni le risque de condensation.De même, la méthode d'essai des performances acoustiques de l'enveloppe peut être utilisée pour comparer différentes constructions, mais pas pour fournir des données acoustiques précises pour des caissons spécifiques.
