ISO 17804:2005 defines the grades and the corresponding requirements for ausferritic spheroidal graphite cast irons. ISO 17804:2005 specifies five grades of ausferritic spheroidal graphite cast iron by a classification based on mechanical properties measured on machined test pieces prepared from separately cast samples or cast-on samples, and samples cut from a casting. ISO 17804:2005 also specifies two grades by a classification as a function of hardness.

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.
