Conditioning is an important part of the test.

Electromechanical Creep Testing Machines The Kappa creep testing machine is equipped with a central lead screw and is suitable for creep tests and advanced creep tests requiring maximum precision in force control.

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.


Specimen strain is recorded by a state-of-the-art measuring system. Data for engineering-design purposes requires the use of extensometers to measure the gauge length of the specimen.

Using this data, creep curves can be generated, which depict the long-term behavior of plastics. Since this type of test runs over a long period of time, it is typical to test multiple specimens at once.

We recommend that you check the website of the publishers of the international document before making a purchase.

They provide slip-free gripping of the specimen, typically specimen type 1A to ISO As the voice of the U. Proof sent to secretariat or FDIS ballot initiated: The testing 8899-2 are equipped with multiple test axes. During a creep test, specimens are subjected to a static load. X Our website uses cookies to ensure that we give you the best user experience. Flexural creep by three-point loading This document has been 899-22 by the committee, and judged to still be up to date.


Final text received or FDIS registered for formal approval. The thermal history of the test specimen can also have profound effects on its creep behaviour see Annex A. It is mounted behind the test axes to allow access to the system by the operator from the front. Isso standard ISO specimen has dimensions of 10 x 4 x 80 mm and is taken from the mid-section of the multi-purpose specimen. It is designed to cover every economic sector and virtually every activity of the humankind where technical standards may be used.

Therefore this version remains current. The test axes are equipped with tensile specimen grips. Check out our FAQs.

This corresponds to the load placed on many components made of plastic. Already Subscribed to this document. Creep tests are described in the following standards: You may delete a document from your Alert Profile at any time.

The isi may not be suitable for determining the flexural creep of rigid cellular plastics attention is drawn in this respect to ISOCellular plastics, rigid — Flexural tests — Part 1: If the document is revised or amended, you will sio notified by email. Experience the ease of intuitive and structured operation that reflects your lab processes.


The test results are as follows: Subscription 89-92 is determined by: We have no document history for this standard. 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. Consequently, when precise comparative results are required, these factors must be carefully controlled. This standard is not included in any packages.

It 8992 important to us that you purchase the right document. 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.

Determination of flexural properties.

Please first log in with a verified email before subscribing to alerts. 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. The electromechanical creep testing machine, KappaMultistationis equipped with a load cell and one drive per test axis.

Proceed to Checkout Continue Shopping. Temperature and humidity are typically recorded isso out the test. A three-point flexure fixture, as described in ISO for flexure testsis used as the flexure test tool.

For this reason it is necessary to ensure that the ambient temperature remains constant throughout the test. By continuing to browse our website, you are agreeing to the use of cookies.
