Reliable test results in plastics testing

Anyone who tests polymer materials or components must be able to rely on the measured results. Plastics exhibit complex mechanical properties that must be determined over a wide range of different loading and environmental conditions, as well as processing history.

ASTM, ISO and many national standards deriving thereof establish the methodology and the framework parameters without which good reproducibility of the properties among testing laboratories as well as suppliers and customers is not possible. In the characterization of molding materials, the ISO 10350 (single-point data), ISO 11403 (multipoint data) and ISO 17282 (design data) standards provide a useful framework that is further detailed by the individual standards in terms of specimen production and testing.

Testing Plastics with ZwickRoell

ZwickRoell operates in close partnership with the plastics industry. Our specialists are actively involved in national and international standards committees, including the occupation of various leading positions. This allows us to be at the source of important information and understand discussions and background information in detail, which is then integrated in the development of standard-compliant and reliable test equipment, ultimately benefiting our customers.

Overview of important standards in plastics testing

Thermoplastics and thermosetting molding materials
A key aspect of the characterization of molding materials is the inter-laboratory reproducibility of test results. Specimen production, specimen shapes, and test sequences are all specified in detail, with rigorous demands on both repeatability and traceability. In quality control, the basic standard of evaluation is the change in measured values over a period of time.

Intermediate products and finished parts
The objectives of testing specimens taken from finished parts or intermediate products differ significantly from those of molding materials testing. That is why there are two different objectives when testing intermediate products and finished parts: functional product characteristics, material properties

Thin sheeting and plastic films
Plastic films have become an integral part of daily life. We use them to package food, carry our groceries home from the store, and cover vegetables grown in greenhouses and fields. Film packaging is common in the medical engineering industry and often saves lives. A wide variety of films are also used in construction.

Testing hard and soft polymer foams
Flexible foam is used in vehicle seat cushions, furniture, mattresses as insulating material, and for acoustic damping. Hard foam is used for thermal and acoustic insulation, as a core material for composites, and also as a substrate material, for example in road construction.

Plastic Pipes
Pipe systems made of thermoplastic polymers or fiberglass reinforced plastics are mainly used for transporting water or gases. They are subject to stringent quality requirements. Due to the wide range of application areas and materials, there are numerous national and international standards used in the testing of plastic pipes. Both the material properties of the plastic and the performance characteristics of the finished pipe are tested. ZwickRoell testing machines are used to perform many of these tests.
