ASTM E604 is a standard test method for dynamic tear (DT) testing of metallic materials. This test method uses specimens with thicknesses ranging from 316 in. to 588 in. (5 mm to 16 mm), inclusive. Inch-pound values should be considered standard.
ASTM E604 Standard Test Method for Dynamic Tear Testing of Metallic Materials
What is ASTM E604?
What is the Scope of ASTM E604?
In research and development, ASTM E604 helps assess the effects of metallurgical variables such as composition, processing, and heat treatment. It is also helpful for fabricating procedures such as forming and welding and for assessing the dynamic rip fracture resistance of new or existing materials. To determine the suitability of a material for a given use in-service evaluation. When minimum Dynamic test energy is required, it is used for information, acceptance specifications, and production quality control.
ASTM E604 Sample Preparation Guide
The specimen blank must be B by 1.60 by 7.125 in. (B by 40.6 by 181.0 mm), where B might be between 316 and 508. (5 to 16 mm).
ASTM E604 Testing Procedure and Requirements
ASTM E604 Tear Testing of Metallic Materials test comprises impact loading a single-edge notched beam in three-point bending and recording the total energy loss during separation. The dynamic test specimen is fractured by the Pendulum or drop-weight machines.
ASTM E604 Analysis Results and Interpretation
l = 0.815ρ 2, to determine l in feet
l = 0.2485ρ2, to determine l in meters
where l is the distance from the axis to the center of percussion, ft (or m), and ρ is a time of a complete cycle (to and fro) of the pendulum, s.

Engineers trust us with what matters most
“We had a great experience working with this company for our ASTM E84 testing. They were the first company to respond to our inquiry within just a few minutes of submitting it. From start to finish, the communication was excellent, and the entire process was swift, straightforward, and hassle-free.”
“Very good communication, testing associates were very patient with delays on our end. Reasonable turnaround time for results and nicely detailed report. Analysts were also quick to answer any follow-up questions. Happy with results.”
“Matestlab connected us with an accredited lab within days, cutting weeks off our product validation timeline.”
