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 sheets or moulded articles. Proof sent to secretariat or FDIS ballot initiated: The method is intended to provide data for engineering-design and research and development purposes.
It is mounted behind the test axes to allow access to the system by the operator from the front. You may delete a document from your Alert Profile at any time. The specimen strain is determined optically by modern creep test systems that use 8899-2 high-precision video measurement system. NOTE The method may be unsuitable for certain fibre-reinforced materials due to differences in fibre orientation. Tensile creep modulus and the nominal tensile creep modulus Creep tensile strength Creep curves with logarithmic time axis Creep module time curves with logarithmic time axis Isochrone stress-strain curves Recovery strain curve.
Flexural creep may vary significantly with differences in specimen preparation and dimensions and in the test environment.
Your Alert Profile lists the documents that will be monitored. Isi corresponds to the load placed on many components made of plastic. A three-point flexure fixture, as described in ISO for flexure 89-2is used as the flexure test tool. You can download and open this file to your own computer but DRM prevents opening this file on another computer, including a networked server. During a creep test, specimens are subjected to a static load.
Proceed to Checkout Continue Shopping. The test load, which is specified prior to the start of the test is based on the polymer characteristics and the intended use, is applied without jolts. Flexural creep by three-point loading. This standard is also available to be included in Standards Subscriptions. Flexural creep by three-point loading Get the latest version of this product.
The method is suitable for use with rigid and semi-rigid non-reinforced, filled and fibre-reinforced plastics materials see ISO for definitions in the form of iiso test specimens moulded directly or machined from sheets or moulded articles. The electromechanical creep testing machine, KappaMultistationis equipped with a load cell and one drive per test axis.
Creep tests on plastics
The specimen strain is recorded over the course of the test, which often lasts 1, hours. Life cycle A standard is reviewed every 5 years 00 Preliminary. Flexure creep modulus Jso flexural strength Creep curves with logarithmic time axis Creep module time curves with logarithmic time axis Isochrone stress-strain curves. We have no amendments or corrections for this standard.
Subscription pricing is determined by: Final text received or FDIS registered for formal approval. If flexural-creep properties are to be used for engineering-design purposes, the plastics materials should be tested over a broad range of stresses, times and environmental conditions. The test load is calculated according to the requirements and must be 89-92 without jolts and then held constant.
It is important to us that you purchase the right document. Standards Subsctiption may be the perfect solution. For this reason kso is necessary to ensure that the ambient temperature remains constant throughout the test.
