Metallic materials - Tensile testing method at high strain rates - Part 1 : elastic-bar-type systems

The two parts of ISO 26203 specify methods for testing metallic sheet materials to determine the stress‑strain characteristics at high strain rates. ISO 26203-1:2010 covers the use of elastic-bar-type systems. The strain-rate range between 10-3 to 103 s-1 is considered to be the most relevant to vehicle crash events based on experimental and numerical calculations such as the Finite Elemental Analysis (FEA) work for crashworthiness. In order to evaluate the crashworthiness of a vehicle with accuracy, reliable stress-strain characterization of metallic materials at strain rates higher than 10-3 s-1 is essential. The test method in ISO 26203-1:2010 covers the strain-rate range above 102 s-1.

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!
