Proof sent to secretariat or FDIS ballot iiso In this way it is possible to achieve statistically verified test results. Tensile creep modulus and the nominal tensile creep modulus Creep tensile strength Creep curves with logarithmic time axis Creep module ido curves with logarithmic time axis Isochrone stress-strain curves Recovery strain curve.
Subscription pricing is determined by: If flexural-creep properties are to be used for engineering-design purposes, the plastics materials should be tested over a broad range of kso, times and environmental conditions.
Flexural creep by three-point loading Get the latest version of this product. Consequently, when precise comparative results are required, these factors must be carefully controlled. Flexure creep modulus Creep flexural strength Creep curves with logarithmic time axis Creep module time curves with logarithmic time ixo Isochrone stress-strain curves. The testing machines are equipped with multiple test axes. As is the case with all flexure tests, the specimen height must be measured carefully.
Check out our FAQs. The specimen strain is determined optically by modern creep test systems that use a high-precision video measurement system.
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. We recommend that you check the website of the publishers of the international document before making a purchase.
Temperature and humidity are typically recorded throughout out the test. The test results are as follows: The company has recently expanded its creep tensile testing capacity by investing in two Kappa Multistation creep testing systems by ZwickRoell. Conditioning is an important part of the test.
It is intended to provide data for engineering-design and research and development purposes. Determination of flexural properties.
We have no amendments or corrections for this standard.
Flexural creep may vary significantly with differences in specimen preparation and dimensions and in the test environment. It is mounted behind the test axes to allow access to the system by the operator from the front.
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. As the voice of the U. If the document is uso or amended, you will be notified by email.

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. It is designed to cover every economic sector and virtually every activity of the humankind where technical standards may be used. Flexural creep 89-92 three-point loading. It is important to us that you purchase the right document. This standard is also available to be included in Standards Subscriptions.
Standards Subsctiption may be the iiso solution.
Final text received or FDIS registered for formal approval. 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.
During a creep test, specimens are subjected to a static load.
