Soil quality - Determination of total cyanide and easily released cyanide - Continuous-flow analysis method

ISO 17380:2004 specifies a method for the photometric determination of the total cyanide and the easily released cyanide mass fraction in soil using an automated-distillation continuous-flow analysis. ISO 17380:2004 applies to all types of soil with cyanide mass fractions above 1 mg/kg on the basis of dry matter, expressed on the basis of the cyanide ion. Sulfide concentrations in the sample higher than 40 mg/kg dry matter cause interference. This effect can be recognized by the split peaks and as a slow decrease of the detector signal and can only be prevented by diluting the sample extract.

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.

With Requirements, quickly access the main part of the normative text!

What is the Redline format?

The Redline + service - standards comparator allows you to easily and simply identify major changes between the current standard and its last canceled version.

At a glance, you will be able to identify the additions, deletions or modifications to a text, table, figure and formula.

The Redlines + service is offered to you on the collection of French standards in force, in French language and in HTML and PDF format.
