ASTM E399 Standard Test Method for Plane - Stress Fracture Toughness of Metallic Materials

EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of ASTM E399 testing. This test method covers the determination of the plane-strain fracture toughness (KIc) of metallic materials by testing using various fatigue cracked specimens with a thickness of 0,063 in (1,6 mm) or more.

This test method also includes determining the specimen strength ratio Rsx, where x represents the specific specimen configuration tested. This strength ratio is a function of the maximum load the specimen can handle, its initial dimensions, and the yield strength of the material.

Measured plane-strain fracture toughness values ​​in inch-pound units should be considered standard.

This test method is divided into two main parts. The first section gives an overview of the recommendations and requirements for Ic testing. The second part consists of appendices giving specific requirements for displacement gauge design, fatigue cracking procedures, and the various sample configurations covered by this method.

This standard does not purport to address the safety issues associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices prior to use and to determine the applicability of regulatory restrictions.
