This standard is also available to be included in Standards Subscriptions. The test load is calculated according to the requirements and must be applied without jolts and then held constant. We recommend that you check the website of the publishers of the international document before making a purchase.
The method may not isoo suitable for determining the flexural creep of rigid cellular plastics attention is drawn in this respect to ISOCellular plastics, rigid — Flexural tests — Part 1: Consequently, when precise comparative results are required, these factors must be carefully controlled.
Subscription pricing is determined by: This standard is not included in any iiso. Since this type 8992- test runs over a long period of time, it is typical to test multiple specimens at once. The thermal history of the test specimen can also have profound effects on its creep behaviour see Annex A.
It is intended to provide data for engineering-design and research and development purposes. Please first verify your email before subscribing to alerts.
Monday to Friday – Data for engineering-design purposes requires the use of extensometers to measure the gauge length of the specimen. They provide slip-free gripping of the specimen, typically specimen type 1A to ISO The test results are as follows: Therefore this version remains current.
Proceed to Checkout Continue Shopping. The testing machines are equipped with multiple test axes. 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 company has recently expanded its creep tensile testing capacity by investing in two Kappa Multistation creep testing systems by ZwickRoell.
Your Alert Profile lists the documents that will be monitored. It is designed to cover every economic sector and virtually every activity of the humankind where technical standards may be used.
You may delete a document from your Alert Profile at any time. NOTE The method may be unsuitable for certain fibre-reinforced materials due to differences in fibre orientation. Ieo tests are described in the following standards: 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.
It is necessary to prevent thermal expansion due to temperature fluctuations, which overlap the creep strain. During a creep test, specimens are subjected to a static load. Temperature and humidity are typically recorded throughout out the test.
Creep tests on plastics
It applies only to a simple freely supported beam loaded at mid-span three-point-loading test. As the voice of the U. Using this data, creep curves can be generated, which depict the long-term behavior of plastics.

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.

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. International Classification for Standards ICS is an international classification system for technical standards. It is mounted behind the test axes to allow access to the ios by the operator from the front.
