ISO 6603-2 Puncture Impact Behavior of Plastics

EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of ISO 6603-2 testing. This standard has resulted in the need for more stringent acceptance criteria regarding the mechanical and chemical properties of plastics.

Because of some of the new structural uses of these materials, it is important to know how they will behave when subjected to dynamic conditions, i.e. impacts. Dynamic failures of materials differ from those found when tested at slower, more constant speeds. This is especially true for plastics, where many variables can affect the material. The way polymers are used to lie within a particular material form material; whether the resins used are filled or unfilled; adding color additives; All forming processes affect the strength and durability of not only the final material but also the end product. Testing according to ISO 6603-2 allows both the materials engineer and the design engineer to test materials for desired properties such as strength, ductility, toughness and energy absorption. .

For this test we used an Instron 22 Drop Tower with optional high energy system equipped with a 20 kN load cell, 9450 mm hemispherical tube attachment, DAS (Data Acquisition system) touch screen board and Bluehill Impact software. We also used our pneumatic clamping system, which can work at room temperature as well as below and above zero degrees, with adapter plates of 40 mm diameter designed according to this standard. The impact mass was 20 kg and the velocity was set to 4.4 m/s, the time interval for data acquisition was set to 30 milliseconds.

To minimize the negative effects of friction between the tube attachment and the sample, the standard requires a lubricant to be applied to its corresponding tip. The 9450 System can be equipped with an automatic lubrication device that guarantees automated and repeatable oil applications. The available energy used for the test should be such that the rate deceleration is not more than 20% from the start of the test to the end of the test. It has been noted that the rate deceleration is less than 20% when the available impact energy is at least three times greater than the energy at peak load.

The tests will be performed under a standard laboratory atmosphere of 23 ± 2 degrees C and 50% relative humidity. By varying the conditioning and testing temperature and testing in a controlled manner at any given impact rate, the temperature at which the material enters a ductile failure mode can be determined for most plastics.

If throughput and resource optimization is a concern, the Instron 9450 can also be used to test up to 30 samples completely unmanned, or up to 10 samples with limited user effort, reducing cycle time and nitrogen fluid consumption.

This test configuration is well suited for determining the performance properties of plastic materials under impact conditions. Plastics suppliers, components and customers alike can use test results to validate product performance. The use of environmental chamber allows both parties to understand how the material can perform in colder or hotter applications.
