NF EN ISO 7539-2

Corrosion of metals and alloys. Stress corrosion testing. Part 2 : preparation and use of bent-beam specimen.

Covers procedures for designing, preparing and using bent-beam test specimens. These specimens may be used to test a variety of product forms (i. e. sheet, plate, flat extruded material, wire or rod). They are espesially suitable for multiple testing and for atmospheric stress corrosion tests; they are usually tested under nominally constant strain conditions. Bent-beam specimens made from high strength materials may fracture rapidly and can be dangerous.

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.
