Water quality - Marine algal growth inhibition test with Skeletonema sp. and Phaeodactylum tricornutum (ISO 10253:2016)
This document specifies a method for the determination of the inhibition of growth of the unicellular
marine algae Skeletonema sp. and Phaeodactylum tricornutum by substances and mixtures contained in
sea water or by environmental water samples (effluents, elutriates, etc.).
The method can be used for testing substances that are readily soluble in water and are not significantly
degraded or eliminated in any other way from the test medium.
NOTE With modifications, as described in ISO 14442 and ISO 5667–16, the inhibitory effects of poorly
soluble organic and inorganic materials, volatile compounds, metal compounds, effluents, marine water samples
and elutriates of sediments can be tested.

Qualité de l'eau - Essai d'inhibition de la croissance des algues marines avec Skeletonema sp. et Phaeodactylum tricornutum (ISO 10253:2016)
ISO 10253:2016 spécifie une méthode de détermination de l'inhibition de la croissance des algues marines unicellulaires Skeletonema sp. et Phaeodactylum tricornutum provoquée par des substances et des mélanges présents dans l'eau de mer (effluents, élutriats, etc.).
Cette méthode peut être utilisée pour soumettre à l'essai des substances facilement solubles dans l'eau et qui ne sont pas sensiblement dégradées ou éliminées d'autre manière du milieu d'essai.
Kakovost vode - Preskus zaviranja rasti morskih alg s Skeletonema sp. in Phaeodactylum tricornutum (ISO 10253:2016)
Ta dokument določa metodo za določevanje zaviranja rasti enoceličnih morskih alg Skeletonema sp. in Phaeodactylum tricornutum s snovmi in zmesmi, ki jih vsebuje morska voda, ali z vzorci okoljske vode (odplake, elutriati itd.).
To metodo je mogoče uporabiti za preskušanje snovi, ki so zlahka topne v vodi in ne razpadejo občutno ali se izločijo na kakršen koli način iz preskusnega medija.
OPOMBA: s spremembami, navedenimi v standardih ISO 14442 in ISO 5667–16, se lahko uporabi za preskušanje zaviralnih učinkov slabo
topnih in anorganskih snovi, hlapnih spojin, kovinskih spojin, odplak, vzorcev morske vode in elutriatov usedlin.

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. Each 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 (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www.iso.org/patents).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.
