ASTM D1004, Standard Test Method for Tear Resistance (Graves Tear) of Plastic Film and Sheeting, is the test method for tear resistance.
ASTM D1004 Standard Test Method for Tear Resistance (Graves Tear) of Plastic Film and Sheeting
At a Glance
Document type: Test Method.
Edition: active, current edition D1004-21.
Property determined: tear resistance.
Values reported: sheeting at a very low rate of loading, 51 mm (2 in.
Scope
Determination of the tear resistance of flexible plastic film and sheeting at a very low rate of loading, 51 mm (2 in.)/min, designed to measure the force to initiate tearing.
Tearing resistance is expressed in maximum newtons (or pounds-force) of force to tear the specimen.
Best reliability for materials that do not fail in a brittle manner and do not elongate more than two hundred percent during testing.
What the Result Tells You
A test to ASTM D1004 returns sheeting at a very low rate of loading and 51 mm (2 in. Each value is reported against the specimen geometry and the conditions the method fixes, which is what makes results from two laboratories directly comparable.
Because the numbers depend on those fixed conditions, a result is only meaningful when the report names the standard, the edition and any options the method allows.
