ASTM D2582

Micom offers ASTM D2582 testing as part of its material testing and polymer testing services . This standard describes a method that can quantify the snagging resistance of a specimen through a puncture propagation of tear test. Furthermore, this test protocol may be employed jointly with another standard such as an accelerated aging test due to the specification of a material.

Tear resistance of a plastic film and thin sheeting—use and factors to consider:

The goal of ASTM D2582 is to assess the ability of a material to withstand a dynamic tearing through a puncture propagation of tear test. The latter consists of evaluating the tear length of a sample after the apparatus’s carriage has stopped its course. From there, it is possible to determine the dynamic tear resistance of a specimen by applying the appropriate formula. Furthermore, by comparing pre-puncture sample with nonperforated ones, it is possible to ascertain the contribution of the puncture towards the force calculated, because for some materials the perforation does not affect significantly the result.
The main factors that are to be considered when running this test are: the carriage employed, the drop height and the number of determinations of the tear length.

Typical Experimental parameters:

The number of samples required is two sets for each direction of tear. The size of the specimen has to be at least 200 mm (8.0 in) long in a rectangular shape. Table 1 lists the typical conditions of the test.
