Water quality - Freshwater algal growth inhibition test with unicellular green algae
ISO 8692:2004 specifies a method for the determination of the growth inhibition of unicellular green algae by substances and mixtures contained in water or by wastewater. The method is applicable for substances that are easily soluble in water. With modifications to this method, as described in ISO 14442 and ISO 5667-16, the inhibitory effects of poorly soluble organic and inorganic materials, volatile compounds, heavy metals and waste water can be tested. A rapid algal growth inhibition screening test for wastewater is also included.

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.
