ASTM E2248 is the test method for notched-bar impact testing of metals using miniaturized Charpy V-notch (mini-CVN) specimens, for use when standard specimens cannot be obtained. To match this to your program, talk with our team.
What ASTM E2248 Covers
It adapts the Charpy V-notch test to sub-size specimens, addressing the specimen geometry, machine energy, and correlation issues that arise at reduced scale, such as for surveillance samples and thin sections.
Why It Matters
Miniature Charpy testing extends toughness evaluation to limited material, but correct sub-size geometry and a suitable low-energy machine are essential for meaningful results.
