It is necessary to prevent thermal expansion due to temperature fluctuations, which overlap the creep strain. It applies only to a simple freely supportet beam loaded at mid-span three-point-loading test.
EVS-EN ISO – Estonian Centre for Standardisation
Data for engineering-design purposes io the use of extensometers to measure the gauge length of the specimen. 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. Standards Subscriptions from ANSI provides a money-saving, multi-user solution for accessing standards. Temperature and humidity are typically recorded throughout out the test. Deflection is measured using either the die movement after correction to the self-deformation of the test arrangement or using a video measuring system.
It is intended to provide data for engineering-design and research and development purposes.
If the document is revised or amended, you will be notified by email. Since this type of test runs over a long period of time, it is typical to test multiple specimens at once.
Creep tests on plastics
We recommend that you check the website of the publishers of the international document before making a purchase. Add to Alert PDF. For this reason it is necessary to ensure that the ambient temperature remains constant throughout the test.
The method may not be suitable for determining the flexural creep of rigid uso plastics attention is drawn in this respect to ISOCellular plastics, rigid — Flexural tests — Part 1: We have ios amendments or corrections for this standard.
Therefore this version remains current. As the voice of the U. Flexure creep modulus Creep flexural strength Creep curves with logarithmic time axis Creep module time curves with logarithmic time axis Isochrone stress-strain curves.
Flexural creep by three-point loading This document has been re-assessed by the committee, and judged to still be up to date. During a creep test, specimens are subjected to a static load. Already Subscribed to this document. The testing machines are equipped with multiple test isl.

Proof sent to secretariat or FDIS ballot initiated: Flexural creep by three-point loading Get the latest version of this product. 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.
The specimen strain is recorded over the course of the test, ieo often lasts 1, hours. Determination of flexural properties. Need more than one copy? A three-point flexure fixture, as oso in ISO for flexure testsis used as the flexure test tool.
This standard is also available to be included in Standards Subscriptions. Proceed to Checkout Continue Shopping. Data for research or quality-control purposes may use the change in distance between the grips nominal extension.
This standard is not included in any packages. International Classification for Standards ICS is an international classification system for technical standards. Check out our FAQs. Flexural creep by three-point loading.

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. Life cycle A standard is reviewed every 5 years 00 Preliminary. The method is suitable for use with rigid and semi-rigid non-reinforced, filled and fibre-reinforced plastics lso see ISO for definitions in the form of dumb-bell-shaped test specimens moulded directly or machined from sheets or moulded articles.
It is mounted behind the test isl to allow access to the system by the operator from the front. Experience the ease of intuitive and structured operation that reflects your lab processes.
