Stationary source emissions - Manual and automatic determination of velocity and volume flow rate in ducts - Part 1: Manual reference method (ISO 16911-1:2013)
ISO 16911-1:2013 specifies a method for periodic determination of the axial velocity and volume flow rate of gas within emissions ducts and stacks. It is applicable for use in circular or rectangular ducts with measurement locations meeting the requirements of EN 15259. Minimum and maximum duct sizes are driven by practical considerations of the measurement devices described within ISO 16911-1:2013.
ISO 16911-1:2013 requires all flow measurements to have demonstrable metrological traceability to national or international primary standards.
To be used as a standard reference method, the user is required to demonstrate that the performance characteristics of the method are equal to or better than the performance criteria defined in ISO 16911-1:2013 and that the overall uncertainty of the method, expressed with a level of confidence of 95 %, is determined and reported. The results for each method defined in ISO 16911-1:2013 have different uncertainties within a range of 1 % to 10 % at flow velocities of 20 m/s.
Methods further to these can be used provided that the user can demonstrate equivalence, based on the principles of CEN/TS 14793.
Emissionen aus stationären Quellen - Manuelle und automatische Bestimmung der Geschwindigkeit und des Volumenstroms in Abgaskanälen - Teil 1: Manuelles Referenzverfahren (ISO 16911-1:2013)
Diese Norm, die ein Verfahren zur periodischen Bestimmung der Axialgeschwindigkeit und des Volumen-stroms von Gasen in Abgaskanälen und –schächten beschreibt, gilt für die Anwendung in runden oder recht-eckigen Abgaskanälen mit Messstellen, die den Anforderungen von EN 15259 entsprechen. Die minimalen und maximalen Kanalmaße sind durch praktische Erwägungen in Bezug auf die in dieser Norm beschriebenen Messgeräte bedingt.
Diese Norm fordert, dass für sämtliche Durchflussmessungen eine metrologische Rückführbarkeit auf nationale oder internationale Primärnormale nachgewiesen werden kann.
Um als ein Standard-Referenzverfahren angewendet zu werden, muss der Anwender nachweisen, dass die Kenngrößen des Verfahrens im Vergleich zu den in dieser Internationalen Norm definierten Kenngrößen gleichwertig oder besser sind, und dass die Gesamtunsicherheit des Verfahrens, angegeben mit einem Vertrauensniveau von 95 %, bestimmt und berichtet wird. Dieses Verfahren kann typischerweise Messungen mit einer Messunsicherheit von 5 % bei Strömungsgeschwindigkeiten von 20 m s–1 erzielen.
Anstelle dieses Verfahrens dürfen alternative Verfahren angewendet werden, vorausgesetzt der Anwender kann auf Grundlage der Grundsätze der Technischen Spezifikation CEN/TS 14793 [1] die Gleichwertigkeit dieser Verfahren nachweisen.
Émissions de sources fixes - Détermination manuelle et automatique de la vitesse et du débit-volume d'écoulement dans les conduits - Partie 1: Méthode de référence manuelle (ISO 16911-1:2013)
L'ISO 16911‑1:2013 spécifie une méthode pour la détermination périodique de la vitesse axiale et du débit-volume du gaz dans les conduits et les cheminées à l'émission de sources fixes. Elle est applicable aux conduits rectangulaires ou circulaires ayant des sections de mesurage répondant aux exigences de l'EN 15259. Les tailles de conduit minimales et maximales sont liées à des considérations pratiques sur les dispositifs de mesurage décrits dans l'ISO 16911‑1:2013.
L'ISO 16911‑1:2013 exige que tous les mesurages de débit aient une traçabilité métrologique démontrable par rapport aux Normes internationales ou aux normes nationales de base.
Pour pouvoir l'utiliser comme méthode de référence normalisée, l'utilisateur est tenu de démontrer que les caractéristiques de performance de la méthode sont égales ou supérieures aux critères de performance définis dans l'ISO 16911‑1:2013 et que l'incertitude globale de la méthode, exprimée à un niveau de confiance de 95 %, est déterminée et déclarée. Pour chaque méthode définie dans l'ISO 16911‑1:2013, les résultats ont des incertitudes différentes comprises dans une plage de 1 à 10 % à des vitesses de 20 m/s.
D'autres méthodes que celles-ci peuvent être utilisées à condition que l'utilisateur puisse démontrer leur équivalence, sur la base des principes de la CEN/TS 14793.
Emisije nepremičnih virov - Ročno in avtomatsko določevanje hitrosti in volumenskega pretoka v odvodnikih - 1. del: Ročna referenčna metoda (ISO 16911-1:2013)
EN ISO 16911-1 določa metodo za redno ugotavljanje aksialne hitrosti in volumenskega pretoka plina v odvodnikih emisij. Uporablja se za krožne in pravokotne odvodnike z meritvenimi mesti, ki so skladni z zahtevami standarda EN 15259. Najmanjše in največje velikosti odvodnikov so določene glede na praktične pomisleke za naprave za merjenje, opisane v standardu EN ISO 16911-1. Po EN ISO 16911-1 morajo biti vse meritve pretoka dokazljivo meroslovno sledljive do nacionalnih ali mednarodnih primarnih standardov. Če se uporablja kot standardna referenčna metoda, mora uporabnik dokazati, da so značilnosti glede zmogljivosti metode enake ali boljše od kriterijev glede zmogljivosti, opredeljenih v standardu EN ISO 16911-1, ter da je treba določiti in poročati o celotni nezanesljivosti metode, izraženo s stopnjo zaupanja 95 %. Rezultati vsake metode, opredeljene v standardu EN ISO 16911-1, imajo različno nezanesljivost znotraj razpona od 1 do 10 % pri hitrostih pretoka 20 m/s. Uporabijo se lahko tudi nadaljnje metode, če lahko uporabnik dokaže enakovrednost, na podlagi načel iz CEN/TS 14793.
