Conditioning is an important part of the test. This standard is not included in any packages. Specimen strain is recorded by a state-of-the-art measuring system. Follow these links to find other Standards similar to the one you are viewing. The standard ISO specimen has dimensions of 10 x 4 x 80 mm and is taken from the mid-section of the multi-purpose specimen.

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. They provide slip-free gripping of the specimen, typically specimen type 1A to ISO Flexural creep by three-point loading This document has been re-assessed by the committee, and judged to still be up to date.

Temperature and humidity are typically recorded throughout out the test. It is mounted behind the test axes to allow access to the system by the operator from the front. The electromechanical creep testing machine, KappaMultistationis equipped with a load cell and one drive per test axis. As the voice of the U. 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.

It is 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. In this way it is possible to achieve statistically verified test results. The thermal history of the test specimen can also have profound effects on its creep behaviour see Annex A.

Subscription pricing is determined by: Along with creep 8992- can be used for quasistatic test methods, for example, to perform a tensile test to ISO You may delete a document from your Alert Profile at any time. It applies only to a simple freely supportet beam loaded at mid-span three-point-loading test. Proof sent to secretariat or FDIS ballot initiated: Determination of flexural properties.

The specimen strain is recorded over the course of the test, which often lasts 1, hours. It is intended to provide data for engineering-design and research and development purposes.

EVS-EN ISO – Estonian Centre for Standardisation

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. The method 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: The test load is calculated according to the requirements and must be applied without jolts and then held constant.

Please first verify your email before subscribing to alerts. The testing machines are equipped with multiple test axes. The method is intended to provide data for engineering-design and research and development purposes.

Using this data, creep curves can be generated, which depict the long-term behavior of plastics. Data for engineering-design purposes requires the use of extensometers to measure the gauge length of the specimen.

NOTE The method may be unsuitable for certain fibre-reinforced materials due to differences in fibre orientation. This corresponds to the load placed on many components made of plastic.

It applies only to a simple freely supported beam loaded at mid-span three-point-loading test.

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. Deflection is measured using either the die movement after correction to the self-deformation of the test arrangement or using a video measuring system.
