ISO 12890:1999

Water quality - Determination of toxicity to embryos and larvae of freshwater fish - Semi-static method

This International Standard specifies a semi-static method for determination of toxicity of chemicals, waters and

wastewaters to embryos and early larval developmental stages of a species of freshwater fish, Danio rerio

(Hamilton-Buchanan), Teleostei, Cyprinidae (common name zebrafish). Where necessary this determination may

include an acute toxicity test using Danio rerio to determine the 96-h LC50 for zebrafish in accordance with

ISO 7346-1, ISO 7346-2 or ISO 7346-3.

The method is also applicable to freshwater fish other than zebrafish if appropriate modifications of the test

conditions are made, particularly with regard to the temperature and volume per fish biomass.

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.
