Metallic materials. Charpy impact test. Part 2 : verification of the testing machine (pendulum impact).

La présente norme décrit deux méthodes de vérification applicables aux machines de flexion par choc qui sont utilisées pour effectuer les essais décrits dans la norme européenne EN 10045-1:1990 (indice de classement A03-011) : -une méthode directe: vérification statique des caractéristiques physiques et géométriques des différentes parties du mouton-pendule, -une méthode indirecte : vérification globale du mouton-pendule à l'aide d'éprouvette charpy V de référence. Un guide de préparation et de caractérisation des éprouvettes de reférence est donné dans une annexe informative.

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!
