ISO 899-2: Plastics flexural creep by three-point loading

← Back to all standards

ISO 899-2 is the test method for the flexural creep of plastics using three-point loading. To match this to your program, talk with our team.

What ISO 899-2 Covers

It measures how a plastic slowly deflects under a constant bending load over time, characterizing long-term flexural performance.

How the Test Is Run

A bar specimen is held under a constant flexural load in a three-point arrangement, usually at controlled temperature, and its deflection is monitored over time to give the flexural creep behaviour.

Why It Matters

Flexural creep data supports long-term design of plastic parts loaded in bending; stable loading and accurate deflection measurement are required.
