Water quality - Marine algal growth inhibition test with Skeletonema costatum and Phaeodactylum tricornutum

ISO 10253:2006 specifies a method for the determination of the inhibition of growth of the unicellular marine algae Skeletonema costatum and Phaeodactylum tricornutum by substances and mixtures contained in sea water.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.

ZOOM ON ... the Requirements department
To comply with a standard, you need to quickly understand its issues in order to determine its impact on your activity.

The Requirements department helps you quickly locate within the normative text:
- mandatory clauses to satisfy,
- non-essential but useful clauses to know, such as permissions and recommendations.

The identification of these types of clauses is based on the document “ISO / IEC Directives, Part 2 - Principles and rules of structure and drafting of ISO documents ”as well as on a constantly enriched list of verbal forms.
