Expression of performance of fluorometric oxygen analyzers in liquid media

IEC 62703:2013 specifies the general aspects in the terminology and definitions related to the performance of fluorometric oxygen analyzers used for the continuous determination of dissolved oxygen partial pressure or concentration in liquid media; unifies methods used in making and verifying statements on the functional performance of such analyzers; specifies which tests should be performed in order to determine the functional performance and how such tests should be carried out and provides basic documents to support the application of standards of quality assurance within ISO 9001.

Izražanje zmogljivosti fluorometričnih analizatorjev kisika v tekočinah (IEC 62703:2013)

Ta mednarodni standard se uporablja za fluorometrične analizatorje kisika, ki se uporabljajo za neprekinjeno določanje delnega tlaka ali koncentracije raztopljenega kisika. Velja za fluorometrične analizatorje kisika, primerne za uporabo v tekočinah, ki vsebujejo vodo, ultra čistih vodah, sladki ali pitni vodi, morski vodi ali drugih vodnih raztopinah, industrijskih ali gospodinjskih odpadnih vodah iz vodnih teles (npr. jezera, reke, ustja) ter za industrijske procesne tokove in procesne tekočine. Čeprav se fluorometrični analizatorji kisika načeloma uporabljajo v plinastih fazah, izražanje delovanja v plinasti fazi ni predmet tega standarda. Senzorska enota fluorometričnega analizatorja kisika, ki je v stiku z medijem za merjenje, vsebuje luminofor v membrani iz polimera, ki je prepustna za kisik, ali v drugih za kisik prepustnih materialih (ali substratih). Ta standard določa terminologijo, definicije, zahteve za navedbe proizvajalcev in preskuse za fluorometrične analizatorje kisika. Ta standard je v skladu s splošnimi načeli iz skupine standardov IEC 60359 in IEC 60770. Ta standard se uporablja za analizatorje, ki so določeni za stalno namestitev na katerem koli mestu (znotraj ali zunaj) z uporabo merilne tehnike s povezavo. Varnostne zahteve so obravnavane v standardu IEC 61010-1. Standardni obseg signalov analognega enosmernega toka, ki se uporabljajo v sistemih za nadzor procesa, je obravnavan v standardu IEC 60381-1. Specifikacije za vrednosti za preskušanje vplivnih veličin so na voljo v skupini standardov IEC 60654. Zahteve za dokumentacijo, ki jo je treba priložiti instrumentom, so obravnavane v standardu IEC 61187. Zahteve za splošna načela glede veličin, enot in simbolov, so obravnavane v standardu ISO 80000-1:2009. Namen standarda IEC 62703 je: – določiti splošne vidike v terminologiji in definicijah v zvezi z delovanjem fluorometričnih analizatorjev kisika, ki se uporabljajo za neprekinjeno določanje delnega tlaka ali koncentracije kisika v tekočih medijih; – poenotiti metode, ki se uporabljajo pri ustvarjanju in preverjanju navedb o funkcijski zmogljivosti takšnih analizatorjev; – določiti, katere preskuse je treba opraviti, da se določi funkcijska zmogljivost, in kako jih je treba opraviti; – zagotoviti osnovne dokumente za podporo uporabe standardov za zagotavljanje kakovosti v sklopu standarda ISO 9001.
