Buy ISO (R) PLASTICS – DETERMINATION OF CREEP BEHAVIOUR – PART 2: FLEXURAL CREEP BY THREE-POINT LOADING from SAI.
We have no document history for this standard. This standard is also available to be included in Standards Subscriptions. 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: Therefore this version remains current. The testing machines are equipped with multiple test axes.
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. This corresponds to the load placed on many components made of plastic.
During a creep test, specimens are subjected to a static load. Flexural creep by three-point loading This document has been re-assessed by the committee, and judged to still be up to date. Final text received or FDIS registered for formal approval.
Flexural creep may vary significantly with differences in specimen preparation and dimensions and in the test environment. We recommend that you check the website of the publishers of the international document before making a purchase.
It is mounted behind the test axes to allow access to the system by the operator from the front. The specimen strain is determined optically by modern creep test systems that use a high-precision video measurement system. 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.

They provide slip-free gripping of the specimen, typically specimen type 1A to ISO 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.
Deflection is measured using either the die movement after correction to the self-deformation of the test arrangement or using a video measuring system. The test load is calculated according to the requirements and must be applied without jolts and then held constant.
It is intended to provide data for engineering-design and research and development purposes. Please first 899–2 in with a verified email before subscribing to alerts. It is important to us that you purchase the right document. The method is intended to provide data for engineering-design and research and development purposes.
The thermal history of the test specimen can also have profound effects on its creep behaviour see Annex A.
If you need help with the purchase or have any queries please email enquiries standards. The company has recently expanded its creep tensile testing capacity by investing in two Kappa Multistation creep testing systems by ZwickRoell.
