Flexural creep by three-point loading. Proof sent to secretariat or FDIS ballot initiated: Conditioning is an important part of the test. This corresponds to the isk placed on many components made of plastic.
EVS-EN ISO 899-2:2004
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. They provide slip-free gripping of the specimen, typically specimen type 1A to ISO The testing machines are equipped with multiple test axes.
Add to Alert PDF. It is important to us that you purchase the right document. We have no document history for this standard. 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.
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: Along with creep testing,they can be used for quasistatic test methods, for example, to perform a tensile test to ISO Final text received or FDIS registered for formal approval.
The thermal history of the test specimen can also have profound effects on its creep behaviour see Annex A. Standards Subsctiption may be the perfect solution. 899- this version remains current. It is designed to cover every economic sector and virtually every activity of the humankind where technical standards may be used. 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 ixo been provided through an international feed.
Flexural creep by three-point loading This document has been re-assessed by the committee, and judged to still ios up to date.
The specimen strain is recorded over the course of the test, which often lasts 1, hours. Flexural creep may vary significantly with differences in specimen preparation and dimensions and in the test environment.
UL Thermoplastics Testing Center – Flexural Creep Test
The isp strain is determined optically by modern creep test systems that use a high-precision video measurement system. Proceed to Checkout Continue Shopping.
Flexural creep by three-point loading Get the latest version of this product. It applies only to a simple freely supportet beam loaded at mid-span three-point-loading test.
Creep tests on plastics
Ios tests above or below ambient temperature, precisely controlled temperature chambers are used. Data for research or quality-control purposes may use the change in distance between the grips nominal extension. 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 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.
Already Subscribed to this document. For this reason it is necessary to ensure that the ambient temperature remains constant throughout the test.
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.

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.
It is mounted behind the test axes to allow access to the system by the operator from the front. Life cycle A standard is reviewed every 5 years 00 Preliminary.
89-2 these links to find other Standards similar to the one you are viewing. Monday to Friday – 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.
Consequently, when precise comparative results are required, these factors must be carefully controlled. Flexure creep modulus Creep flexural strength Creep curves with logarithmic time axis Creep module time curves with logarithmic time axis Isochrone stress-strain 89-2.
Determination of flexural properties. Temperature and humidity are typically recorded throughout out the test.
International Classification for Standards ICS is an international classification system for technical standards.
Experience the ease of intuitive and structured operation that reflects your lab processes. As is the case with all flexure tests, the specimen height must be measured carefully.
