This test method may be used to characterize the toughness of materials for which the properties and thickness of interest preclude the determination of K lc fracture toughness in accordance with Test Method Eallowing the use of sub-sized specimens astm e1290 estimate K Ic.

We will work with you to guarantee a test machine that fits your application. The loading rate is slow and influences of e120 other than temperature are not covered. E290 to Active This link will always route to the current Active version of the standard. The aatm of the test specimen is also an important consideration because it can actually affect the measured CTOD values.
