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. 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. Standards Subsctiption may be the perfect solution.
A three-point flexure fixture, as isso in ISO for flexure testsis used as the flexure test tool.

This corresponds to the load placed on many components made of plastic. 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. Check iiso our FAQs.
The materials covered range from simple polyolefins to high-performance thermoplastics. 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. It is mounted behind the test axes to 899–2 access to the system by the operator from the front. Along with creep testing,they can be used for quasistatic test methods, for example, to perform a tensile test to ISO 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 suitable for use with rigid and semi-rigid non-reinforced, filled and fibre-reinforced plastics materials see ISO for definitions in the form of dumb-bell-shaped test specimens moulded directly or machined from sheets or moulded articles.
The testing machines are equipped with multiple test axes. As the voice of the U. The electromechanical creep testing machine, KappaMultistationis equipped with a load cell and one drive per test axis. Proceed to Checkout Continue Shopping. Please first verify your email before subscribing to alerts. The method may not be suitable for determining the flexural creep of rigid cellular plastics attention is drawn in this respect to ISOCellular 899-22, rigid — Flexural tests — Part 1: It applies only to a simple freely supported beam loaded at mid-span three-point-loading test.
Since this type of test runs over a long period of time, it is typical to 899-22 multiple specimens at once. The uso results are as follows: Flexure creep modulus Creep flexural strength Creep curves with logarithmic time axis Creep module time curves with logarithmic time axis Isochrone stress-strain curves. Experience the ease of intuitive and structured operation that reflects your lab processes.
Your Alert Profile lists the documents that will be monitored.
Flexural creep may vary significantly with differences in specimen preparation and dimensions and in the test environment. Add to Alert PDF. Standards Subscriptions from ANSI provides a money-saving, multi-user solution for accessing standards. Temperature and humidity are typically recorded throughout out the test. You may delete a document from your 89-2 Profile at any time. We recommend that you check the website of the publishers of the international document before making a purchase.
The specimen strain is recorded over the course of the test, which often lasts 1, hours.

The test axes are equipped with tensile specimen grips. As is kso case with all flexure tests, the specimen height must be measured carefully. The thermal history of the test specimen can also have profound effects on its creep behaviour see Annex A. This standard is not included in any packages. Flexural creep by three-point loading This document has been re-assessed by the committee, and judged to still be up to date.
Data for research or quality-control purposes may use the change in distance between the grips nominal extension. Specifies a method for determining the flexural creep of plastics in the form of standard test specimens under specified conditions such as those of pretreatment, temperature and humidity. Therefore this version remains current. International Classification for Standards ICS is an international classification system for technical 89-2.

It is important to us that you purchase the right document. The company has recently expanded its creep tensile testing capacity by investing in two Kappa Multistation creep testing systems by ZwickRoell. Follow these links to find other Standards similar to the one you are viewing.
The test load, which is specified prior to the start of the test is based on the polymer characteristics and the iiso use, is applied without jolts.
