Email addresses must contain the symbol. Non-repeatability of results — ASTM D requires the operator to exclude results that deviate markedly from the mean value.
Assurance Enabling you to identify and mitigate the intrinsic risk in your operations, supply chains and business processes. Instron self-tightening c1004 are primarily designed for the precision testing of films and other flexible materials exhibiting a large reduction in cross-section area under load.
Please confirm that you agree with our privacy and cookies policy to submit this form. In most cases, comparison between films of dissimilar x1004 is not valid.
This test method aims to measure force to initiate tear for plastic films that do no exhibit brittle failure or do not elongate greater than Actual use performance in tearing of some plastics may not necessarily correlate with data from this test method.
Concrete, Asphalt and Rock. Whether your business is local or global, we can ensure your products meet quality, health, environmental, safety, and social accountability standards for virtually any market around the world. 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.
Assurance Testing Inspection Certification. Software for Series Systems. Therefore, the tearing resistance is expressed in maximum newtons or pounds-force of force to tear the specimen. Contact Us View Accessories Catalog. Inspection Validating the specifications, value and safety of your raw materials, products and assets. The specimen geometry of this test method produces a stress concentration in a small area of the specimen.
ASTM D – TEAR RESISTANCE
Tear resistance measures the ultimate force required to tear film or sheet. Bluehill LE for Basic Testing. They are designed with standard and optional features that increase testing efficiency and improve the testing experience for the operator. Note 1 — Film has been arbitrarily defined as sheeting wstm nominal thickness not greater than 0.
Tear Resistance ASTM D
The specimen is die cut to the appropriate shape from a sheet. Discover simpler and smarter testing with features such as pre-loaded test methods, QuickTest in seconds, enhanced data exporting: The values given in parentheses are provided for information only.
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. Testing Evaluating how your products and services meet and exceed quality, safety, sustainability and performance standards. The specimen is then placed in the grips of the testing machine and pulled at a rate of 2 in.
Need help or have a question? Formally confirming that your products and services meet all trusted external and internal standards. Preventing specimen slippage — When testing thin films, the specimens typically undergo thinning as they are stretched. ASTM D covers the determination of tear strength or tear resistance of flexible plastic film and sheeting.
