You may delete a document from your Alert Profile at any time. 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.

Flexural creep by three-point loading. For this reason it is necessary to ensure that the ambient temperature remains constant throughout the test. Already Subscribed to this document. The company has lso expanded its creep tensile testing capacity by investing in two Kappa Multistation creep testing systems by ZwickRoell. A three-point flexure fixture, as described in ISO for flexure testsis used as the flexure test tool.

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. For tests above or below ambient temperature, precisely controlled temperature chambers are used.


If the document is revised or amended, you will be notified by email. This standard is also available to be included in Standards Subscriptions. Data for research or quality-control purposes may use the change in distance between the grips nominal extension. The method is intended to provide data for engineering-design and research and development purposes.

Creep tests on plastics

It applies only to a simple freely supportet beam loaded at mid-span three-point-loading test. This corresponds to the load placed on many components made of plastic.

The electromechanical creep testing machine, KappaMultistationisso equipped with a load cell and one drive per test axis. The materials covered range from isp polyolefins to high-performance thermoplastics. Standards Subscriptions from ANSI provides a money-saving, multi-user solution for accessing standards.

We have no document history for this standard. This standard is not included in any packages. Data for engineering-design purposes requires the use of extensometers to measure the gauge length of the specimen. International Classification for Standards ICS is an international classification system for technical standards. It is designed to cover every economic sector and virtually every 8999-2 of the humankind where technical standards may be used.

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.

The specimen strain is recorded over the course of the 899- which often lasts 1, hours. Please first verify your email before subscribing to alerts. Although we endeavour to maintain an up-to-date catalogue, on occasion we may not have the latest version of a document, including where it has not yet been provided through an international feed.

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: Flexural creep by three-point loading This document has been re-assessed by the committee, and judged to still be up to date. It applies only to a simple freely supported beam loaded at mid-span three-point-loading test. The standard ISO specimen has dimensions of 10 x 4 x iao mm and is taken from the 899–2 of the multi-purpose specimen.

The specimen strain is determined optically by modern creep test systems that use a high-precision video measurement system. Monday to Friday – This part of the 8999-2 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.

Using this data, creep curves can be generated, which depict the long-term behavior of plastics. The test axes are equipped with tensile specimen grips. Standards Subsctiption may be the perfect solution. Consequently, io precise comparative results are required, these factors must be carefully controlled.

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