Thermal performance of buildings and materials - Determination of specific airflow rate in buildings - Tracer gas dilution method (ISO 12569:2017)

ISO 12569:2017 establishes methods to obtain the ventilation rate or specific airflow rate in a building space (which is considered to be a single zone) using a tracer gas.
The measurement methods apply for spaces where the combined conditions concerning the uniformity of tracer gas concentration, measurement of the exhaust gas concentration, effective mixed zone and/or fluctuation of ventilation are satisfied.
ISO 12569:2017 provides three measurement methods using a tracer gas: concentration decay method, continuous dose method, and constant concentration method.
NOTE          Specific measurement conditions are given in Table 1.

Wärmetechnisches Verhalten von Gebäuden und Werkstoffen - Bestimmung des spezifischen Luftvolumenstroms in Gebäuden - Indikatorgasverfahren (ISO 12569:2017)

Dieses Dokument legt Verfahren zur Bestimmung der Luftwechselrate oder des spezifischen Luftvolumenstroms in einem Raum eines Gebäudes (der als aus einer einzelnen Zone bestehend angesehen wird) mittels eines Indikatorgases fest.
Diese Messverfahren gelten für Räume, in denen die kombinierten Bedingungen zur gleichmäßigen Indikatorgaskonzentration, eine Messung der Abgaskonzentration, eine wirksame Mischzone und/oder ein Luftwechsel vorliegen.
Dieses Dokument umfasst drei Messverfahren, bei denen Indikatorgas zum Einsatz kommt: Verfahren mit abfallender Konzentration, Verfahren mit konstanter Injektion und Verfahren mit konstanter Konzentration.
ANMERKUNG Die spezifischen Messbedingungen sind in Tabelle 1 angegeben.

Performance thermique des bâtiments et des matériaux - Détermination du débit d'air spécifique dans les bâtiments - Méthode de dilution de gaz traceurs (ISO 12569:2017)

ISO 12569:2017 établit des méthodes permettant d'obtenir le taux de ventilation ou le débit d'air spécifique dans un espace intérieur d'un bâtiment (considéré comme ne comprenant qu'une seule zone) à l'aide d'un gaz traceur.
Les méthodes de mesure s'appliquent aux espaces où les conditions combinées relatives à l'uniformité de la concentration du gaz traceur, le mesurage de la concentration du gaz, la zone de mélange réelle et/ou la fluctuation de la ventilation sont satisfaites.
Le présent document donne trois méthodes de mesure à l'aide d'un gaz traceur: la méthode par décroissance de la concentration, la méthode par dose continue et la méthode par concentration constante.
NOTE          Les conditions de mesurage spécifiques sont indiquées dans le Tableau 1.

Toplotna izolacija v stavbah - Ugotavljanje števila izmenjav zraka v stavbah - Metoda redčenja indikatorskega plina (ISO 12569:2017)

Ta dokument določa metode za pridobitev stopnje prezračevanja ali števila izmenjav zraka v stavbnem prostoru (ki se šteje za eno območje) z uporabo indikatorskega plina.
Merilne metode se uporabljajo za prostore, v katerih so izpolnjeni kombinirani pogoji v zvezi z enotnostjo
koncentracije indikatorskega plina, merjenjem koncentracije izpušnega plina, učinkovito mešano cono in/ali pretokom ventilacije.
Ta dokument določa tri merilne metode z indikatorskim plinom: metodo razgradnje koncentracije, metodo nepretrganega odmerka in metodo stalne koncentracije.
OPOMBA: Posebni pogoji za merjenje so podani v preglednici 1.
