We have no amendments or corrections for this standard. In this way it is possible to achieve statistically verified test results.
Specimen strain is recorded by a state-of-the-art measuring system. The test results are as follows: 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 989-2 test axes.

Creep tests on plastics
This part of the standard specifies a isp 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.

Monday to Friday – Tensile creep modulus and the nominal tensile creep modulus Creep tensile io Creep curves with logarithmic time axis Creep module time curves with logarithmic time axis Isochrone stress-strain curves Recovery strain curve.
The specimen strain is recorded over the course of the test, which often lasts 1, hours. Data for engineering-design purposes requires the use of extensometers to measure the gauge length of the specimen. Along with creep testing,they can be used for quasistatic test methods, for example, to perform a tensile test to ISO Creep tests are described in the following standards: Deflection is measured using either the die movement after correction to the self-deformation of the test arrangement or using a video measuring system.
Therefore this version remains current. The specimen strain is determined optically by modern creep test systems that use a high-precision iao measurement system. It is designed ido cover every economic sector and virtually every activity of the humankind where technical standards may be used. We have no document history for this standard. Standards Subsctiption may be the perfect solution. The thermal history of the test specimen can also have profound effects on its creep behaviour see Annex A.
Conditioning is an important part of the test. Already Subscribed to this document.
Check out our FAQs. For this reason it is necessary to ensure that the ambient temperature remains constant throughout the test. NOTE The method may be unsuitable for certain fibre-reinforced materials due to differences in fibre orientation. The test load is calculated according to the requirements and must be applied without jolts and then held constant.
