ASTM D1004 PDF
Tear Resistance ASTM D Scope: Tear resistance measures the ultimate force required to tear film or sheet. It is often used for quality control checks or for . ASTM D covers the determination of tear strength or tear resistance of flexible plastic film and sheeting. The site of tear is initiated by a high stress.

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.
Bluehill Universal Software is built from the ground-up for touch interaction and an intuitive user experience. The specimen geometry and speed of testing in this test method are controlled to produce tearing in a small area of stress concentration ast, rates far below those usually encountered in service.
The specimen is die cut to the appropriate shape from a sheet. Please confirm that you agree with our privacy and cookies policy to submit this form. Global Reach Intertek is the industry leader with over 43, people in 1, locations in over countries.
Non-repeatability of results — ASTM D requires the operator to exclude results that deviate markedly from the mean value. Contact Us Request an Accessory Catalog. Tear resistance measures the ultimate force required to tear film or sheet.

Tear Resistance ASTM D1004
D0104 Consulting Sourcing Training. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Note ast — Film has been arbitrarily defined as sheeting having nominal thickness not greater than 0.
Email addresses must contain the symbol. The values given in parentheses are provided for information only. Note 2—There is no similar or equivalent ISO standard. The method is not applicable for film or sheeting material where brittle failures occur during testing or where maximum extension is greater than This test method aims to measure force to initiate tear for plastic films that do no exhibit brittle failure or do not elongate d104 than Therefore, the tearing resistance is expressed in maximum newtons or pounds-force of force to tear the specimen.
It is the responsibility of the user of this standard to establish appropriate safety and health e1004 and determine the applicability of regulatory atm prior to use. Die C specimens are commonly used. Hence, tearing forces measured in newtons or pounds-force cannot be normalized over a wide range of specimen thickness without producing misleading data as to the actual tearing resistance of the material. 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.

ASTM D Tear Resistance (Graves Tear) of Plastic Film and Sheeting – Instron
The specimen geometry of this test method produces a stress concentration in a small area of the specimen. Note 1—Film has been arbitrarily defined as sheeting having nominal thickness not greater than 0. Work Item s – proposed revisions of this standard. The maximum stress, usually found near the onset of tearing, is recorded as the tear resistance in newtons or pounds-force.
They are designed with standard and optional features that increase testing efficiency and improve the testing experience for the operator. Preventing specimen slippage — When testing thin films, the specimens typically undergo thinning as they are stretched.
