They are designed with standard and optional features that increase testing efficiency and improve the testing experience for the operator. Therefore, the tearing resistance is expressed in maximum newtons or pounds-force of force to tear the specimen. The average thickness of the specimen is measured. The resistance is measured in Newtons. Link to Active This link will always route to the current Active version of the standard.

Experience has shown the test to have its best reliability for materials which do not have brittle failure or do not elongate greater than two hundred percent during testing.
Active Risk Management
The method is not applicable for film or sheeting material where brittle failures occur during testing or where maximum extension is greater than Subscribe to Our Newsletters. Work Item s – proposed revisions of this standard. The shape of the specimen is designed to create a tear when the specimen is pulled in tension. Users of previous versions of software such as Bluehill 2 and Bluehill 3 can easily upgrade to the newest version of Bluehill.
Note 2 — There is no known ISO equivalent to this standard. Preventing specimen slippage — When testing thin films, the specimens typically undergo thinning as they are stretched. Contact Us View Accessories Catalog. In most cases, comparison between films of dissimilar thickness is not valid. Discover simpler and smarter 1d004 with features such as pre-loaded test methods, QuickTest in seconds, enhanced data exporting: Next Checking to see if aatm are a returning visitor….
Actual use performance in tearing of some plastics may not necessarily correlate with data from this test method. S1004 of results Preventing specimen slippage Solutions: Tear resistance measures the ultimate force required to tear film or sheet. Die C specimens are commonly used. The challenges of testing to this standard are: Certification Formally confirming that your products and services meet all trusted external and internal standards.
It is often used for quality control checks or for material comparison where tear failures are possible. Formally confirming that your products s1004 services meet all trusted external and internal standards. The maximum stress, usually found near the onset of tearing, is recorded as the tear resistance in newtons or pounds-force.

Instron self-tightening grips are primarily designed for the precision testing of films and other flexible materials exhibiting a large reduction in cross-section area under load. Send us a request Need help or have a question?
For this test, we recommend a Series or Series single column electromechanical frame. How can we help you?
Bluehill Universal also offers a TestCam module to record a video of the test, enabling users to replay videos to ensure a test performed as expected. Concrete, Asphalt and Rock.
ASTM D – TEAR RESISTANCE
The specimen geometry and speed of testing in this test method are controlled to produce tearing in a small area of stress concentration at rates far below those usually encountered in service.
