The testing machines are equipped with multiple test axes. 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 test axes are equipped with tensile specimen grips.
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. 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.
EVS-EN ISO 899-2:2004
Therefore this version remains current. Specimen strain is recorded by a state-of-the-art measuring system. Standards Subscriptions from ANSI provides a money-saving, multi-user solution for accessing standards. The test results are as follows: For tests above or below ambient temperature, precisely controlled temperature chambers are used.
Proof sent to secretariat or FDIS ballot initiated: International Classification for Standards ICS is an international classification system for technical standards. It is designed to cover every economic sector and virtually every activity of the humankind where technical standards may be used. Standards Subsctiption may be the perfect solution.

It is intended to provide data for engineering-design and research and development purposes. The method may not 899-2 suitable for determining the flexural creep of rigid cellular plastics attention is drawn in this respect to ISOCellular plastics, rigid — Flexural tests — Part 1: If you need help with the purchase or have any queries please email enquiries standards.

Flexural creep by three-point loading This document has been re-assessed by the committee, and judged to still be up to date. Flexural creep by three-point loading Get the latest version of this product. Using this data, creep curves can be generated, which depict the long-term behavior of plastics.
UL Thermoplastics Testing Center – Flexural Creep Test
The test load is calculated according to the requirements and must be applied without jolts and then held constant. The specimen strain is recorded over the course of the test, which often lasts 1, hours. It applies only to a 8999-2 freely supportet beam loaded at mid-span three-point-loading test.
The thermal history of the test specimen can also have profound effects on its creep behaviour see Annex Is. Proceed to Checkout Continue Shopping. Consequently, when precise comparative results are required, these factors must be carefully controlled.
As is the case with all flexure tests, the specimen height must be measured carefully. Determination of flexural properties.
NOTE The method may be unsuitable isl certain fibre-reinforced materials due to differences in fibre orientation. A three-point flexure fixture, as described in ISO for flexure testsis used as the flexure test tool. As the voice of the U. The materials covered range from simple polyolefins to high-performance thermoplastics. It is mounted behind the test axes to allow access to the system by the operator from the front.
Final text received or FDIS registered for formal approval. The specimen strain is determined optically by modern creep test systems that use a high-precision video measurement system. It is necessary to prevent thermal 899-2 due to temperature fluctuations, which overlap the creep strain. We have no document history for this standard.
Deflection is measured using either the die movement after correction to the self-deformation of the test arrangement or using a video measuring system. This part of the standard 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.
The company has recently expanded its creep tensile testing capacity by investing in two Kappa Multistation creep testing systems by ZwickRoell.
