Due to some of the new structural uses of these materials, it is essential to know how they will behave when subjected to 6603-2 conditions — i. Dynamic failures of materials are different then those found when testing at slower, steadier speeds.
Testing per ISO allows both the material engineer and the design engineer to test materials for desired properties such as strength, ductility, toughness and energy absorption. We also used our pneumatic clamping system with 40 mm diameter adapter plates designed in accordance to this standard.
Impact mass was 20 kg and the velocity was set at 4. ISO states that the specimens may be left unclamped.
ISO 6603-2 Puncture Impact Behavior of Rigid Plastics
However, it is noted that the test results obtained for clamped and unclamped specimens may be different due to the freedom of movement that the specimen has away from the impact point. The free movement of the edges may cause vibrations with higher amplitudes in the data. To minimize the adverse effects of friction that occurs between the tup insert and the specimen, the standard calls for the application of a lubricant, such as Vaseline, on the striker tip.
The test values obtained with the lubricated striker are lower than the unequivocal lower limits of the tested mechanical properties of the material.
By changing the conditioning and testing temperature, and testing in a controlled manner at any given impact velocity, the temperature at which the material transitions from a ductile to brittle failure mode can be established for most plastics. This test configuration is 6630-2 suited for determining the performance characteristics of plastic materials under impact conditions.
Both plastic suppliers and their customers may use test results to verify product performance.
Environmental chamber use allows both parties to get an understanding of how the material may perform in colder or warmer applications. Impact resistance is one of the most important properties for component designers to consider, as well as the most difficult to quantify.
Impact resistance is a critical measure of service life and more importantly these days, it involves the perplexing problem of product safety and liability. Subscribe to Instron News! Check this box to receive pertinent commercial email from Instron focusing on products, upcoming events, and more!
