UL Thermoplastics Testing Center – Flexural Creep Test
Deflection is izo using either the die movement after correction to the self-deformation of the test arrangement or using a video measuring system. This corresponds to the load placed on many components made of plastic. If you need help with the purchase or have any queries please email enquiries standards.
Using this data, creep 8999-2 can be generated, which depict the long-term behavior of plastics. As is the case with all flexure tests, the specimen height must be measured carefully. Data for engineering-design purposes requires the use of extensometers to measure the gauge length of the specimen.
It applies only to a simple freely supportet beam loaded at mid-span ios test. The thermal history of the test specimen can also have profound effects on its creep behaviour see Annex A.
The test results are as follows: Please first log in with a verified email before subscribing to alerts. Determination of flexural properties. It is mounted behind the test axes to allow access to the system by the operator from the front.
Temperature and humidity are typically recorded throughout out the test. Specimen strain is recorded by a state-of-the-art measuring system. We recommend that you check the website of the publishers of the international document before making a purchase.
Monday to Friday – Add to Alert PDF. Standards Subsctiption may be the perfect solution. Subscription pricing is determined by: The materials covered range from simple polyolefins to high-performance thermoplastics.
It applies only to a simple freely supported beam loaded at mid-span three-point-loading test. It is intended to provide data for engineering-design and research and development purposes.
Flexure creep modulus Creep flexural strength Creep curves with logarithmic time axis Creep module iwo curves with logarithmic time axis Isochrone stress-strain curves.
The method is suitable for use with rigid and semi-rigid non-reinforced, filled and fibre-reinforced plastics materials in the form of rectangular bars moulded directly or cut from isk or moulded articles. In this way it is possible to achieve statistically verified test results.
Flexural creep by three-point loading Get the latest version of this product. This part of the standard specifies a method for determining the flexural creep of plastics in the form of standard test specimens under specified conditions such as those of pre-treatment, temperature and humidity. Although we endeavour to maintain an up-to-date catalogue, on occasion we may not have the latest version of a document, including where it has not yet been provided through an international feed. You can download and open this file to your own computer but DRM prevents opening this file on another computer, including a networked server.
The method is intended to provide data for engineering-design and research and development purposes. The test load is calculated according to the requirements and must be applied without 8999-2 and then held constant.
Flexural creep may vary significantly with differences in specimen preparation and dimensions and in 899- test environment.
