Ce test d\u00e9termine l&#039;\u00e9nergie n\u00e9cessaire \u00e0 un pendule pour frapper un \u00e9chantillon afin de le briser.<\/li>\n<li><strong>Test d&#039;impact Charpy\/Izod instrument\u00e9\u00a0:<\/strong> Ce test est une version avanc\u00e9e des tests Charpy et Izod. Il utilise des instruments sp\u00e9cialis\u00e9s pour enregistrer l&#039;\u00e9nergie absorb\u00e9e par l&#039;\u00e9chantillon lors de l&#039;impact.

La force d&#039;impact et la vitesse du poids sont utilis\u00e9es pour mesurer l&#039;\u00e9nergie absorb\u00e9e par l&#039;\u00e9chantillon. Ce test \u00e9value la r\u00e9sistance du mat\u00e9riau aux impacts soudains et ponctuels.<\/li>\n<li><strong>Test d&#039;impact de balle\u00a0:<\/strong> Une balle en acier ou en caoutchouc est l\u00e2ch\u00e9e ou lanc\u00e9e \u00e0 une vitesse fixe sur l&#039;\u00e9chantillon test\u00e9. La d\u00e9formation de l&#039;\u00e9chantillon est enregistr\u00e9e et l&#039;\u00e9nergie absorb\u00e9e est calcul\u00e9e. Le test d\u00e9termine la r\u00e9sistance aux chocs des mat\u00e9riaux utilis\u00e9s dans les \u00e9quipements sportifs et les automobiles.<\/li>\n<li><strong>Essai d&#039;impact de traction\u00a0:<\/strong> L&#039;essai d&#039;impact de traction fait r\u00e9f\u00e9rence \u00e0 l&#039;application d&#039;une force d&#039;impact \u00e0 une position sp\u00e9cifique de l&#039;\u00e9chantillon afin que l&#039;\u00e9chantillon soit soumis \u00e0 une force de traction jusqu&#039;\u00e0 ce qu&#039;il se brise.
