Water quality - Evaluation in an aqueous medium of the "ultimate" aerobic biodegradability of organic compounds - Method by analysis of biochemical oxygen demand (closed bottle test) (ISO 10707:1994)

Specifies a method, by analysis of biochemical oxygen demand, for the evaluation in an aqueous medium of the "ultimate" biodegradability of organic compounds at a given concentration by aerobic microorganisms. The method applies to all organic compounds which are sufficiently water soluble to prepare a stock solution or poorly water soluble when using special dosing techniques.

Wasserbeschaffenheit - Bestimmung der vollständigen aeroben biologischen Abbaubarkeit organischer Stoffe in einem wäßrigen Medium - Verfahren mittels Bestimmung des biochemischen Sauerstoffbedarfs (Geschlossener Flaschentest) (ISO 10707:1994)

Diese Internationale Norm beschreibt ein Verfahren zur Bestimmung der vollständigen biologischen Abbaubarkeit einer organischen Substanz bei einer vorgegebenen Konzentration in einem wäßrigen Medium durch aerobe Mikroorganismen. Die in dieser Internationalen Norm beschriebenen Bedingungen entsprechen nicht immer den optimalen Bedingungen, um einen maximalen biologischen Abbaugrad zu erreichen.

Qualité de l'eau - Evaluation en milieu aqueux de la biodégradabilité aérobie ultime des composés organiques - Méthode par anylyse de la demande biochimique en oxygène (essai en fiole fermées) (ISO 10707:1994)

La présente Norme internationale prescrit une méthode, par analyse de la demande biochimique en oxygène, d'évaluation de la biodégradabilité «ultime» de composés organiques présents à une concentration donnée sous l'action de micro-organismes aérobies. Les conditions décrites dans la présente Norme internationale ne correspondent pas nécessairement aux conditions optimales d'obtention de la biodégradation maximale. La méthode s'applique à tout composé organique suffisamment soluble dans l'eau pour préparer une solution mère ou peu soluble dans l'eau à l'aide de techniques de dosage particulières. En général, en raison de la faible concentration en composé à expérimenter au début de l'essai, il n'est pas nécessaire de prendre des précautions spéciales relatives à la toxicité du composé à expérimenter vis-à-vis des micro-organismes de l'inoculum. Si nécessaire, un essai d'inhibition peut être effectué en parallèle.

Foreword
ISO (the International Organization for Standardization) is a worldwide
federation of national Standards bodies (ISO member bodies). The work
of preparing International Standards is normally carried out through ISO
technical committees. Esch member body interested in a subject for
which a technical committee has been established has the right to be
represented on that committee. International organizations, governmental
and non-governmental, in liaison with ISO, also take part in the work. ISO
collaborates closely with the International Electrotechnical Commission
(1 EC) on all matters of electrotechnical standardization.
Draft International Standards adopted by the technical committees are
circulated to the member bodies for voting. Publication as an International
Standard requires approval by at least 75 % of the member bodies casting
a vote.
International Standard ISO 10707 was prepared by Technical Committee
lSO/TC 147, Water quality, Subcommittee SC 5, Biological methods.
Annexes A, B and C of this International Standard are for information only.
