Increased demand has resulted in the need for more demanding acceptance criteria with respect to the mechanical and chemical properties of plastics. Due to some of the new structural uses of these materials, it is essential to know how they will behave when subjected to dynamic conditions – i.e. impacts. Dynamic failures of materials are different then those found when testing at slower, steadier speeds. This is especially true of plastics where many variables can affect the material – the way the polymers are used to make a specific material form/lie in the material; whether the resins used are filled or unfilled; addition of color additives; forming processes all affect the strength and durability of not only the end material but the end product as well. Testing per ISO 6603-2 allows both the material engineer and the design engineer to test materials for desired properties such as strength, ductility, toughness and energy absorption.
